Why does adding buttons to grid view causes text-view to change?

Why does adding buttons to grid view causes text-view to change? - java

My android activity workout view displays a grid view. Each object of grid view either displays the name of an exercise and two buttons or it displays a exercise set and two buttons.This is what it looks like when I don't add buttons to each set.
Once I enable buttons to each set by commenting out deleteBtn.setVisibility(View.GONE); the activity displays this. changing the 3rd to last object to display an exercise instead of a set. (Scrolled down)
getLocation(int i) determines if an grid object is going to be an Exercise or set. location[0] determines the exercise and location1 if == 0 refers to exercise and location1 > 0 refers to an exercise set.
private int[] getLocation(int i) {
db = new DatabaseHelper(context);
int temp[] = {-1, -1};
int count = -1;
for (int we = 0; we < WE_TABLE.size(); we++) {
for (int s = 0; s < db.getSetCountByWEID(WE_TABLE.get(we).getID()) + 1; s++) {
count++;
if (count == i) {
//Log.e("Test","WE: " + we+ " S: " + s + " For: " + i);
temp[0] = we;
temp[1] = s;
db.closeDB();
return temp;
}
}
}
db.closeDB();
return temp;
}
public View getView(int position, View convertView, ViewGroup parent) {
int temp_p = position;
TextView tv;
View view = convertView;
if (view == null) {
totalObj++;
Obj = totalObj;
int[] location = getLocation(Obj - 1);
db = new DatabaseHelper(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.activity_workout_view_gridview, null);
tv = new TextView(context);
tv.setLayoutParams(new GridView.LayoutParams(GridView.LayoutParams.FILL_PARENT, GridView.LayoutParams.WRAP_CONTENT));
Button deleteBtn = (Button) view.findViewById(R.id.delete_btn);
Button addBtn = (Button) view.findViewById(R.id.add_btn);
tv = (TextView) view.findViewById(R.id.list_item_string);
String Exercises = (Obj + " " + location[0] + "," + location[1]);
Log.e("Test", "Location: " + location[0] + " , " + location[1] + " Number " + Obj);
if (location[1] == -1) {
} else if (location[1] == 0) {
WorkoutExercise WE = WE_TABLE.get(location[0]);
Exercises = WE.getExerciseName();
// addBtn.setVisibility(View.GONE);
//deleteBtn.setVisibility(View.GONE);
} else {
S_TABLE = db.getSets(WE_TABLE.get(location[0]).getID() + "");
Exercises = S_TABLE.get(location[1] - 1).getWeight() + "lbs " + S_TABLE.get(location[1] - 1).getReps() + " Reps";
addBtn.setVisibility(View.GONE);
//deleteBtn.setVisibility(View.GONE);
}
deleteBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do something
}
});
addBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do something
}
});
tv.setText(Exercises);
db.closeDB();
}
return view;
}
And My XML for each row is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:paddingLeft="8dp"
android:textSize="18sp"
android:textStyle="bold" />
<Button
android:id="#+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="0dp"
android:text="Dele" />
<Button
android:id="#+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/delete_btn"
android:layout_centerVertical="true"
android:layout_marginRight="0dp"
android:text="Add" />
</RelativeLayout>

I lowered the height to match the text and It is working properly, thanks to talex

list view change item randomly

I have a listview that when I change the value of one item (count) with click on plus button, Everything is fine as long as the user do scroll down and show more items
And we see that on each page of the scroll has changed a value of item!!!

Remove notifyDataSetChanged from if-else conditions, May this will work
public void filter(String s, ImageView img) {
HashMap<String, Object> wp = new HashMap<>();
if (!s.equals("")) {
fdata.clear();
for (int i = 0 ;i<data.size();i++) {
wp = data.get(i);
if (wp.get("name").toString().toLowerCase().contains(s)) {
fdata.add(wp);
//notifyDataSetChanged();
}
}
}
else {
fdata = new ArrayList<>(selecteddata);
//notifyDataSetChanged();
}
notifyDataSetChanged();
}

you can use NestedScrollview outside the listview and stop the scrolling of listview by using this: smoothScrollBy(0, 0);

How to fix ArrayAdapter changing positions when listView scrolls?

I still not used a ViewHolder class, (I know about the performance of the list view, and will implement it as soon as possible) but I already try overwrite those two methods on array adapter (getViewTypeCount() and getItemViewType) but continue not working.
At my standpoint my array adapter onle handle with ONE type of view, so theoretically I didn't have to overwrite those methods, but i dont know what is happening, just when I scroll my listView the positions get disorganized.
My ArrayAdapter:
private Context context;
private ArrayList<Task> taskArrayList;
public TasksAdapter(#NonNull Context c, #NonNull ArrayList<Task> objects) {
super(c, R.layout.task_row, objects);
this.context = c;
this.taskArrayList = objects;
}
#Override
public int getViewTypeCount() {
return taskArrayList.size();
}
#Override
public int getItemViewType(int position) {
return position;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(
Context.LAYOUT_INFLATER_SERVICE );
Task task = taskArrayList.get(position);
View view = inflater.inflate(R.layout.task_row, parent, false);
if(TaskActivity.getIsClicked() && TaskActivity.getPositionClicked()-1 == position){
view.setBackgroundResource(R.color.backgroundSelectedItem);
}
TextView timeTextView = view.findViewById(R.id.timeTextView);
TextView taskNameView = view.findViewById(R.id.taskNameText);
TextView dateTextView = view.findViewById(R.id.dateTextView);
FloatingActionButton fab = view.findViewById(R.id.myFabTask);
SimpleDateFormat sdf = new SimpleDateFormat("EEE, d MMM");
String dateString = sdf.format(task.getDate());
int hour = (int) task.getTime()/3600000;
int minutes = (int) (task.getTime() % 3600000) / 60000;
String stringHour = Integer.toString(hour);
String stringMinutes = Integer.toString(minutes);
if(stringHour.length() == 1){stringHour = "0"+stringHour;}
if(stringMinutes.length() == 1){stringMinutes = "0"+stringMinutes;}
String timeString = stringHour+":"+stringMinutes;
timeTextView.setText(timeString);
taskNameView.setText(task.getName());
dateTextView.setText(dateString);
return view;
}
My Main code where i call and use the adapter:
mTaskListView = findViewById(R.id.task_list_view);
refreshAdapter();
isClicked = false;
positionClicked = 0;
mTaskListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(positionClicked == (position+1) || positionClicked == 0){
if(!isClicked){
isClicked = true;
positionClicked = position+1;
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
changeLayoutVisibility(1);
Task task = adapter.getItem(position);
parent.getChildAt(position).setBackgroundColor(getResources().getColor(R.color.backgroundSelectedItem));
}else {
isClicked = false;
positionClicked = 0; mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
changeLayoutVisibility(0);
parent.getChildAt(position).setBackgroundColor(Color.WHITE);
}
}
}
});
Function on Main activity:
private void refreshAdapter() {
adapter = null;
//Get the array with tasks
adapter = new TasksAdapter(this, mDBAdapter.getAllTask());
//Set the list view
mTaskListView.setAdapter(adapter);
}

You said that your adapter only handle with ONE type of view but:
When #Override getViewTypeCount() you return the size of taskArrayList, so the system understand that you have taskArrayList.size() type of view. In your case, it should be 1.
List item In getItemViewType() method, the value return must is the identify of view type, not the item's position. In your case also, it should return 0 as default.
Hope it help!

I just solve it by changing:
parent.
getChildAt(position).
setBackgroundColor(getResources().getColor(R.color.backgroundSelectedItem));
By:
view.setBackgroundResource(R.color.backgroundSelectedItem);

Don't do following operations in getView().
//get and format the date
SimpleDateFormat sdf = new SimpleDateFormat("EEE, d MMM");
String dateString = sdf.format(task.getDate());
//convert the milliseconds to minute and hour
int hour = (int) task.getTime()/3600000;
int minutes = (int) (task.getTime() % 3600000) / 60000;
String stringHour = Integer.toString(hour);
String stringMinutes = Integer.toString(minutes);
if(stringHour.length() == 1){stringHour = "0"+stringHour;}
if(stringMinutes.length() == 1){stringMinutes = "0"+stringMinutes;}
String timeString = stringHour+":"+stringMinutes;
Create new Function which return type is String and call that function in timeTextView.setText.
Make function Like this:
private String getTimeStirng(Object date){
//get and format the date
SimpleDateFormat sdf = new SimpleDateFormat("EEE, d MMM");
String dateString = sdf.format(date);
//convert the milliseconds to minute and hour
int hour = (int) task.getTime()/3600000;
int minutes = (int) (date % 3600000) / 60000;
String stringHour = Integer.toString(hour);
String stringMinutes = Integer.toString(minutes);
if(stringHour.length() == 1){stringHour = "0"+stringHour;}
if(stringMinutes.length() == 1){stringMinutes = "0"+stringMinutes;}
String timeString = stringHour+":"+stringMinutes;
return timeString;
}
Call it like: timeTextView.setText(getTimeString(task.getDate()));
Thanks.
Happy Coding.

Speeding up big set of programmatically created buttons display

I have an activity which generates a scrollable list (let's say a column) of programmatically created buttons from a List which is the result of an sqlite table read and my problem is that as the List is growing (and so the number of buttons) the initial painting of the screen is becoming slow (at the moment is taking 3 seconds with 50 buttons to draw) so I'm looking for a solution to this.
At first I thought of using a thread (runnable, handler or whatever is best), let's say creating a new thread inside the For which iterates over the list but it's not working (or at least I'm not being able to make it to work) so my question is the next:
Starting from a List<> which is the most appropiate way to create a big set of scrollable buttons so users doesn't have such delay when accesing the screen.
Paginating could be an option, but I'd like to know about other possibilities first and leave that as a last resource.
Thanks, and below is my code.
public static void createButtons(LinearLayout llContainer,
List<TestType> TestTypes, List<Test> Tests,
int buttonFontSize) {
Context oContext = llContainer.getContext();
String strTheme = TMAppearance.getThemeFromPreferences(oContext);
testMe = ((ApplicationConfiguration)oContext.getApplicationContext());
int callerActivity = TestTypes!=null ? 2 : 1;
if (TestTypes!=null || Tests!=null) {
int lCols = strTheme.equals(testMe.theme_vivid) ? 1 : 2;
//int sourceElementIndex = 0;
int originListSize = calculateOriginalListSize(callerActivity, TestTypes, Tests);
int lRows = (int) Math.ceil((double)originListSize/lCols);
List<String> aStartColors = TMUtils_ThemeVivid.generateStartColorArray(lRows, oContext);
List<String> aEndColors = TMUtils_ThemeVivid.generateEndColorArray(lRows, oContext);
for (i = 0; i < lRows; i++) {
LinearLayout outerButtonLayout = generateOuterButtonLayout(oContext);
for (j = 0; j < lCols; j++) {
final Thread r = new Thread() {
public void run() {
LinearLayout innerButtonLayout = generateInnerButtonLayout(oContext);
outerButtonLayout.addView(innerButtonLayout, j);
if (sourceElementIndex<originListSize){
final TMButton oButton = new TMButton(oContext);
if (callerActivity==1) { //testMenu
setTestMenuButtonSettings(oButton, sourceElementIndex, Tests);
} else {
if (callerActivity==2) { //testTypeMenu
setTestTypeMenuButtonSettings(oButton, sourceElementIndex, TestTypes);
}
}
if (strTheme.equals(testMe.theme_vivid)){
oButton.fontSize = buttonFontSize;
oButton.gradientStartColor = aStartColors.get(i);
oButton.gradientEndColor = aEndColors.get(i);
}else{
if (strTheme.equals(testMe.theme_purple)){
oButton.gradientStartColor = testMe.btnStartColor_purple;
oButton.gradientEndColor = testMe.btnEndColor_purple;
}
}
configureButton(oButton, callerActivity);
oButton.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Context oContext = v.getContext();
TMButton oButton = (TMButton) v;
int callerActivity = Integer.valueOf(v.getTag().toString().split("#")[0]);
String sourceId = String.valueOf(v.getTag().toString().split("#")[1]);
if(event.getAction() == MotionEvent.ACTION_DOWN) { //pressed
setButtonPressed(oButton);
TMSound.playButtonSound(oContext);
} else if (event.getAction() == MotionEvent.ACTION_UP) { //released
setButtonReleased(oButton);
startTargetActivity(callerActivity, sourceId, oContext);
}
return true;
}
});
TMAppearance.doButtonAnimation(oContext, oButton, i);
innerButtonLayout.addView(oButton);
sourceElementIndex++;
}
}
};
r.run();
}
llContainer.addView(outerButtonLayout);
}
}
}

0X0nosugar is correct. A RecycleView will provide better performance, but many beginners have more difficulty implementing it and with only 50 buttons performance shouldn't really be an issue. And although I generally like to abide by the rule 'Use the best available solution' I think it is still appropriate to learn how to implement the ListView. So...
You will need to create a custom adapter:
public class MyListDataAdapter extends ArrayAdapter<MyListData> {
private static final String TAG = "MyListDataAdapter";
public MyListDataAdapter(Context context, ArrayList<MyListData> data) {
super(context, 0, data);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
final MyListData data = getItem(position);
if(convertView == null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.edit_list_item, parent, false);
}
// Add a TextView if you need one
final TextView tvName = (TextView) convertView.findViewById(R.id.tvName);
Button btnEditTicketHolder = (Button) convertView.findViewById(R.id.btnEdit);
btnEditTicketHolder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
long userId = data.getUserId();
String fName = data.getFirstName();
Intent intent = new Intent(getContext(), EditActivity.class);
intent.putExtra("userId", userId);
intent.putExtra("fName", fName);
getContext().startActivity(intent);
}
});
String name = data.getFirstName();
tvName.setText(name);
return convertView;
}
}
Now you need your MyListData class to hold the data:
public class MyListData {
// Add more as you need
private long userId;
private String firstName;
public MyListData(){
}
public void setFirstName(String name){ this.firstName = name; }
public void setUserId(long id){ this.userId = id; }
public String getFirstName(){ return this.firstName; }
public long getUserId(){ return this.userId; }
}
Your custom ListView layout could look something like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
>
<TextView
android:id="#+id/tvName"
android:text="With Whom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
>
<Button
android:id="#+id/btnEdit"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:paddingRight="10dp"
android:paddingLeft="10dp"
android:text="Edit"
android:backgroundTint="#color/colorAccent"
android:focusable="false"
/>
</LinearLayout>
</RelativeLayout>
In your Activity (eg. in the onCreate() method) where the ListView you will need to populate the data for the ListView. This should not be done on the UI Thread
ArrayList<MyListData> arrayListData = new ArrayList<MyListData>();
MyListDataAdapter adapter = new MyListDataAdapter(this, arrayListData);
for (MyListData g : result) {
adapter.add(g);
}
mLstMy.setAdapter(adapter);
Also in the activity where the ListView is to be maintained set up some onClick event handlers if you need them:
(I find that one of the small advantages of the ListView is that the onClick event is easier it implement than in the RecycleView)
mMyLst = (ListView) findViewById(lstMy);
mMyLst.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long l) {
MyListData data = (MyListData) parent.getItemAtPosition(position);
selectedName = data.getName();
Intent intent = new Intent(ShowListDataActivity.this, MainActivity.class);
startActivity(intent);
}
});
mMyLst.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
MyListData data = (MyistData) adapterView.getItemAtPosition(i);
selectedName = data.getFirstName();
selectedTicketPosition = i;
// removeValue is my own method for removing an entry from the
// list MyListData and then call adapter.notifyDataSetChanged();
removeValue(i);
return true;
}
});

how to add scrollview dynamically to dynamic table rows

I am new to android.I have table layout in XML and dynamically adding rows,i am trying to put dynamic rows into scrollview.please anyone help how to do.
Here my xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
<include layout="#layout/header"
android:id="#+id/header" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tv_message"
android:textSize="18sp"
android:textAlignment="center"
android:background="#deb8"
android:layout_below="#id/header"
android:textColor="#000000"
android:text="Please Confirm the Quote and check for Errors "/>
<ScrollView
android:id="#+id/ScrollView03"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_message" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_message"
android:id="#+id/table_orderfulfillment"
android:stretchColumns="*">
</TableLayout>
</ScrollView>
</Relative Layout>

Okay i have tried to Populate Tablelayout dynamically through String Array
here is the code: scrollview is also added.
public class MainActivity extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
String[] row = { "ROW1", "ROW2", "Row3", "Row4", "Row 5", "Row 6",
"Row 7"
};
String[] column = { "COLUMN1", "COLUMN2", "COLUMN3", "COLUMN4",
"COLUMN5", "COLUMN6"
};
int rl=row.length;
int cl=column.length;
ScrollView sv = new ScrollView(this);
TableLayout tableLayout = createTableLayout(row, column,rl, cl);
HorizontalScrollView hsv = new HorizontalScrollView(this);
hsv.addView(tableLayout);
sv.addView(hsv);
setContentView(sv);
}
private TableLayout createTableLayout(String [] rv, String [] cv,int rowCount, int columnCount)
{
// 1) Create a tableLayout and its params
TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();
TableLayout tableLayout = new TableLayout(this);
tableLayout.setBackgroundColor(Color.BLACK);
// 2) create tableRow params
TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();
tableRowParams.setMargins(1, 1, 1, 1);
tableRowParams.weight = 1;
for (int i = 0; i < rowCount; i++)
{
// 3) create tableRow
TableRow tableRow = new TableRow(this);
tableRow.setBackgroundColor(Color.BLACK);
for (int j= 0; j < columnCount; j++)
{
// 4) create textView
TextView textView = new TextView(this);
// textView.setText(String.valueOf(j));
textView.setBackgroundColor(Color.WHITE);
textView.setGravity(Gravity.CENTER);
String s1 = Integer.toString(i);
String s2 = Integer.toString(j);
String s3 = s1 + s2;
int id = Integer.parseInt(s3);
Log.d("TAG", "-___>"+id);
if (i ==0 && j==0)
{
textView.setText("0==0");
}
else if(i==0)
{
Log.d("TAAG", "set Column Headers");
textView.setText(cv[j-1]);
}
else if( j==0)
{
Log.d("TAAG", "Set Row Headers");
textView.setText(rv[i-1]);
}
else
{
textView.setText(""+id);
// check id=23
if(id==23)
{
textView.setText("ID=23");
}
}
// 5) add textView to tableRow
tableRow.addView(textView, tableRowParams);
}
// 6) add tableRow to tableLayout
tableLayout.addView(tableRow, tableLayoutParams);
}
return tableLayout;
}
}
output:

I'm using this code to load more data on scroll.!
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrollStateChanged(RecyclerView recyclerView,
int newState) {
super.onScrollStateChanged(recyclerView, newState);
// If scroll state is touch scroll then set userScrolled
// true
if (newState == AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {
userScrolled = true;
}
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx,
int dy) {
super.onScrolled(recyclerView, dx, dy);
// Here get the child count, item count and visibleitems
// from layout manager
visibleItemCount = mLayoutManager.getChildCount();
totalItemCount = mLayoutManager.getItemCount();
pastVisiblesItems = mLayoutManager
.findFirstVisibleItemPosition();
// Now check if userScrolled is true and also check if
// the item is end then update recycler view and set
// userScrolled to false
if (userScrolled
&& (visibleItemCount + pastVisiblesItems) == totalItemCount) {

}
}

I created same before like this
You can use the HashMap map = new HashMap<>(); for what item user click. I assume that you use two button click are available in adapter class if not then add it.
Step 1 First Declare the HashMap map = new HashMap<>(); in adapter.
Step 2 Then put value in HashMap map.put("key","value"); This code put in both plus and minus button click event.
Step 3 Call ShowHashMapValue(); method below to the map.put("key","value"); for see the HashMap values check logcat for that.
Compare this adapter code for understand easily if any problem just comment below.
ListAdapter.java
public class ListAdapter extends BaseAdapter {
public ArrayList<Integer> quantity = new ArrayList<Integer>();
public ArrayList<Integer> price = new ArrayList<Integer>();
private String[] listViewItems, prices, static_price;
TypedArray images;
View row = null;
static String get_price, get_quntity;
int g_quntity, g_price, g_minus;
private Context context;
CustomButtonListener customButtonListener;
static HashMap<String, String> map = new HashMap<>();
public ListAdapter(Context context, String[] listViewItems, TypedArray images, String[] prices) {
this.context = context;
this.listViewItems = listViewItems;
this.images = images;
this.prices = prices;
for (int i = 0; i < listViewItems.length; i++) {
quantity.add(0);
}
}
public void setCustomButtonListener(CustomButtonListener customButtonListner) {
this.customButtonListener = customButtonListner;
}
#Override
public int getCount() {
return listViewItems.length;
}
#Override
public String getItem(int position) {
return listViewItems[position];
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ListViewHolder listViewHolder;
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = layoutInflater.inflate(R.layout.activity_custom_listview, parent, false);
listViewHolder = new ListViewHolder();
listViewHolder.tvProductName = (TextView) row.findViewById(R.id.tvProductName);
listViewHolder.ivProduct = (ImageView) row.findViewById(R.id.ivproduct);
listViewHolder.tvPrices = (TextView) row.findViewById(R.id.tvProductPrice);
listViewHolder.btnPlus = (ImageButton) row.findViewById(R.id.ib_addnew);
listViewHolder.edTextQuantity = (EditText) row.findViewById(R.id.editTextQuantity);
listViewHolder.btnMinus = (ImageButton) row.findViewById(R.id.ib_remove);
static_price = context.getResources().getStringArray(R.array.Price);
row.setTag(listViewHolder);
} else {
row = convertView;
listViewHolder = (ListViewHolder) convertView.getTag();
}
listViewHolder.ivProduct.setImageResource(images.getResourceId(position, -1));
listViewHolder.edTextQuantity.setText(quantity.get(position) + "");
listViewHolder.tvProductName.setText(listViewItems[position]);
listViewHolder.tvPrices.setText(prices[position]);
listViewHolder.btnPlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (customButtonListener != null) {
customButtonListener.onButtonClickListener(position, listViewHolder.edTextQuantity, 1);
quantity.set(position, quantity.get(position) + 1);
//price.set(position, price.get(position) + 1);
row.getTag(position);
get_price = listViewHolder.tvPrices.getText().toString();
g_price = Integer.valueOf(static_price[position]);
get_quntity = listViewHolder.edTextQuantity.getText().toString();
g_quntity = Integer.valueOf(get_quntity);
map.put("" + listViewHolder.tvProductName.getText().toString(), " " + listViewHolder.edTextQuantity.getText().toString());
// Log.d("A ", "" + a);
// Toast.makeText(context, "A" + a, Toast.LENGTH_LONG).show();
// Log.d("Position ", "" + position);
// System.out.println(+position + " Values " + map.values());
listViewHolder.tvPrices.getTag();
listViewHolder.tvPrices.setText("" + g_price * g_quntity);
ShowHashMapValue();
}
}
});
listViewHolder.btnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (customButtonListener != null) {
customButtonListener.onButtonClickListener(position, listViewHolder.edTextQuantity, -1);
if (quantity.get(position) > 0)
quantity.set(position, quantity.get(position) - 1);
get_price = listViewHolder.tvPrices.getText().toString();
g_minus = Integer.valueOf(get_price);
g_price = Integer.valueOf(static_price[position]);
int minus = g_minus - g_price;
if (minus >= g_price) {
listViewHolder.tvPrices.setText("" + minus);
}
map.put("" + listViewHolder.tvProductName.getText().toString(), " " + listViewHolder.edTextQuantity.getText().toString());
ShowHashMapValue();
}
}
});
return row;
}
private void ShowHashMapValue() {
/**
* get the Set Of keys from HashMap
*/
Set setOfKeys = map.keySet();
/**
* get the Iterator instance from Set
*/
Iterator iterator = setOfKeys.iterator();
/**
* Loop the iterator until we reach the last element of the HashMap
*/
while (iterator.hasNext()) {
/**
* next() method returns the next key from Iterator instance.
* return type of next() method is Object so we need to do DownCasting to String
*/
String key = (String) iterator.next();
/**
* once we know the 'key', we can get the value from the HashMap
* by calling get() method
*/
String value = map.get(key);
System.out.println("Key: " + key + ", Value: " + value);
}
}
}

So so here is logic. You need to declare a boolean in PSP. by default set it to false.
Now when + button will be triggered you need to set that boolean check to true
then in your set price create this logic.
public String getPrice() {
if(check==true){
price++;
}
else{
price--;
}
return price;
}
If i correctly understand you then this surely will help you. Good Luck!
