Custom adapter for listview using pasrequery

Custom adapter for listview using pasrequery - java

I am trying to create a demo app where the users enter a search and destination, the data will be queried from parse.com and then the matching result will be displayed in the next screen's listview. I have followed a few tutorials but for sure haven't been able to grasp the concept concretely enough. When I enter a search query, the progress bar shows up and then the application goes back into the previous activity. I can't understand where exactly things are going wrong.
This is my mainactivity class.
public class CarpoolingActivitySearch extends ActionBarActivity {
ListView listView;
ArrayList<Travellers> travellers;
CarpoolingAdapter adapter;
protected ProgressDialog proDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_carpooling_activity_search);
final EditText mSrc = (EditText)findViewById(R.id.carpooling_source);
final EditText mDst = (EditText)findViewById(R.id.destination);
Button mSubmitButton = (Button)findViewById(R.id.carpooling_submit);
mSubmitButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String source = mSrc.getEditableText().toString();
String destination = mDst.getEditableText().toString();
listView = (ListView) findViewById(R.id.list);
ParseQuery<ParseObject> query = ParseQuery.getQuery("Carpooling");
query.whereEqualTo("Source", source); //assume you have a DonAcc column in your Country table
query.whereEqualTo("Destination", destination); //assume you have a DonAcc column in your Country table
startLoading();
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> parseObjects, ParseException e) {
if(e==null)
{
for(int i=0;i<parseObjects.size();i++)
{
Travellers travellers1 = new Travellers();
travellers1.setSource("Source");
travellers1.setDestination("Destination");
travellers.add(travellers1);
if(travellers.size() > 0)
{
adapter = new CarpoolingAdapter(getApplicationContext(),R.layout.activity_carpooling_activity_search,travellers);
listView.setAdapter(adapter);
} else {
AlertDialog.Builder popup = new AlertDialog.Builder(CarpoolingActivitySearch.this);
popup.setMessage("Seems our servers are busy. Try again in some time.");
popup.setPositiveButton("Back",null);
AlertDialog dialog = popup.create();
dialog.show();
}
}
stopLoading();
finish();
}
else {
stopLoading();
AlertDialog.Builder popup = new AlertDialog.Builder(CarpoolingActivitySearch.this);
popup.setMessage(e.getMessage());
popup.setPositiveButton("Back",null);
AlertDialog dialog = popup.create();
dialog.show();
}
}
});
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_carpooling_activity_search, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
protected void startLoading() {
proDialog = new ProgressDialog(this);
proDialog.setMessage("loading...");
proDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
proDialog.setCancelable(false);
proDialog.show();
}
protected void stopLoading() {
proDialog.dismiss();
proDialog = null;
}
}
I have created a custom adapter for this purpose.
public class CarpoolingAdapter extends ArrayAdapter<Travellers> {
ArrayList<Travellers> travellersArrayList;
LayoutInflater vi;
int Resource;
ViewHolder holder;
Context context;
public CarpoolingAdapter(Context context, int resource, ArrayList<Travellers> objects) {
super(context, resource, objects);
vi = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Resource = resource;
travellersArrayList = objects;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView== null) {
convertView = vi.inflate(Resource,null);
holder = new ViewHolder();
holder.mSource = (TextView)convertView.findViewById(R.id.textView);
holder.mDestination = (TextView)convertView.findViewById(R.id.textView2);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
holder.mSource.setText(travellersArrayList.get(position).getSource());
holder.mDestination.setText(travellersArrayList.get(position).getDestination());
return convertView;
}
static class ViewHolder {
public TextView mSource;
public TextView mDestination;
}
}
And the travellers class with a default constructor and getter/setter methods.
public class Travellers {
private String Source;
private String Destination;
public Travellers() {
}
public Travellers(String source, String destination) {
super();
Source = source;
Destination = destination;
}
public String getSource() {
return Source;
}
public void setSource(String source) {
Source = source;
}
public String getDestination() {
return Destination;
}
public void setDestination(String destination) {
Destination = destination;
}
}
The main layout file named activity_carpooling_activity_search.xml.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

What should I modify to make it work appropriately? I am not getting any errors as such.

First of all, you have posted a very long code blocks where indentation is not good enough to read you code.
So what I understood, as your ParseException e is null that means there is no exception. Inside that if block, after the for loop you are calling finish() which is causing your current activity instance to be destroyed thus going to previous activity.
I hope this helps you.

ViewPager inside Dialog not showing

I have a custom dialog that has a ViewPager inside of it, when the dialog shows the ViewPager is just blank, not progressing on swipe or when pressing the "Next" button I implemented. I tried slightly altering my code and it didn't work. I saw several posts like this, but none of their solutions worked. PS if some things don't make sense or have mismatched names then that's because I renamed/removed some of the files/variables to simplify.
SliderAdapter:
public class SliderAdapter extends PagerAdapter {
private Context context;
private LayoutInflater layoutInflater;
private ArrayList<String> text;
public SliderAdapter(Context context, ArrayList<String> text) {
this.context = context;
this.text = text;
}
public String[] txtH = {
"test1",
"test2",
"test3"
};
#Override
public int getCount() {
return txtH.length;
}
#Override
public boolean isViewFromObject(#NonNull View view, #NonNull Object object) {
return view == (ConstraintLayout) object;
}
#NonNull
#Override
public Object instantiateItem(#NonNull ViewGroup container, int position) {
layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.slide_layout_wr, container, false);
TextView txt1 = view.findViewById(R.id.txt11);
TextView txt2 = view.findViewById(R.id.txt22);
txt1.setText(txtH[position]);
txt2.setText(text.get(position));
container.addView(view);
return view;
}

The problem is that you didn't set the ViewPager adapter
public class DialogWeeklyReport extends AppCompatDialogFragment {
...
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
...
viewPager = view.findViewById(R.id.viewPager);
...
adapter = new SliderAdapter(getActivity(), text);

Here is my test

Set text inside fragment not working after revisiting fragment

I am developing an bus time table android app. I have three fragments.
Inside first fragment I have two radio buttons i.e. From Malegaon & To Malegaon. (Malegaon is name of place).
If I select From Malegaon radio button then I am setting text to sourceEditText as Malegaon. and If I select To Malegaon radio button then I am setting text to destinationEditText as Malegaon.
This condition is working fine, when I visit fragment first time, but if I revisit fragment then From Malegaon radio Button is already selected, sourceEditText is blank and destinationEditText has text as Malegaon.
Here is my snapshot and code for first fragment.
after selecting to Malegaon radio button.
I am just changing visibility of layout. (source edittext,destination edittext,search button is one layout)

} else if (position == 2) {

}
}
after revisiting OldStandFragment it look like this.
I checked with adding logs everywhere possible. And I found that after revisiting OldStandFragment, toOldMalegoanRadioButton.setOnClickListner() method is getting called.
Now I want to refresh fragment when I re-visit or any other way to solve this issue.

You have to use SharedPreferences to save state of checkbox, try this code
public class StackOne extends AppCompatActivity {
SharedPreferences prefs;
private RadioButton rButton1, rButton2;
private RadioGroup rg_ContainerOld;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.stack_one);
prefs = PreferenceManager.getDefaultSharedPreferences(StackOne.this);
rButton1 = (RadioButton) findViewById(R.id.fromOldMalegoanRadioButton);
rButton2 = (RadioButton) findViewById(R.id.toOldMalegoanRadioButton);
rg_ContainerOld = (RadioGroup) findViewById(R.id.rg_ContainerOld);
GetSelectedRadioButton();
int k = prefs.getInt("rb1", 0);
if (k == 1) {
rButton1.setChecked(true);
sourceEditTextFromMalegoanOld.setText("");
} else if (k == 2) {
rButton2.setChecked(true);
sourceEditTextToMalegoanOld.setText("");
}
}
private void GetSelectedRadioButton() {
rg_ContainerOld.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (group.getCheckedRadioButtonId()) {
case R.id.fromOldMalegoanRadioButton:
prefs.edit().putInt("rb1", 1).commit();
break;
case R.id.toOldMalegoanRadioButton:
prefs.edit().putInt("rb1", 2).commit();
break;
}
}
});
}
}

In your code you are dynamically setting checked state of radiobutton
fromOldMalegoanRadioButton.setChecked(true);
toOldMalegoanRadioButton.setChecked(false);
thats why your radiobutton's oncheckedchanged method will get call. And thats why code in it.

How do I use the swipe gesture to remove cards within a recycleview?

How do I use the swipe gesture to remove cards from my recycle-view in the same way that it is done in Google-now etc. So far I've created the cardview application but it's removing cards via a swipe gesture which I'm having problems with. I haven't found a single tutorial or question answered on this website which could help.
Any help would be very much appreciated. My code is below.
MyActivity
public class MyActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_my);
setContentView(R.layout.activity_my);
RecyclerView recList = (RecyclerView) findViewById(R.id.cardList);
recList.setHasFixedSize(true);
LinearLayoutManager llm = new LinearLayoutManager(this);

You can use below code (ItemTouchHelper.SimpleCallback from Android support V7) to remove the cards from RecyclerView using swipe gesture
ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
#Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
return false;
}
#Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
contacts.remove(viewHolder.getAdapterPosition());
ca.notifyItemRemoved(viewHolder.getAdapterPosition());
}
#Override
public void onMoved(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, int fromPos, RecyclerView.ViewHolder target, int toPos, int x, int y) {
super.onMoved(recyclerView, viewHolder, fromPos, target, toPos, x, y);
}
};
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback);
itemTouchHelper.attachToRecyclerView(recList);

Android - Confirmation Dialog for Delete button inside ListView row

I'm looking for a way to implement a dialog which asks for confirmation when clicking on the delete button of my ListView row. I tried to do it inside my custom ArrayAdapter, but as it is no Activity I don't know how to do it.
When I put the whole onClick-Listener inside the MainActivity, I have no clou how to find out which position the button was clicked so that I can remove it afterwards.
public class ServiceAdapter extends ArrayAdapter<Service> {
private final Singleton singleton = Singleton.getInstance();
private ArrayList<Service> services;
public ServiceAdapter(Context context, ArrayList<Service> services) {
super(context, 0, services);
this.services = services;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Service service = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(
R.layout.listview_row, parent, false);
}
// Lookup view for data population
TextView quantity = (TextView) convertView
.findViewById(R.id.QUANTITY_CELL);
TextView description = (TextView) convertView
.findViewById(R.id.DESCRIPTION_CELL);
Button delete = (Button) convertView.findViewById(R.id.BUTTON_DELETE);
// Populate the data into the template view using the data object
quantity.setText(String.valueOf(service.getQuantity()));
description.setText(service.getDescription());
// Set up the listener for the delete button.
final View view = convertView;
view.setTag(Integer.valueOf(position));
delete.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Integer index = (Integer) view.getTag();
services.remove(index.intValue());
notifyDataSetChanged();
}

Listview w/ custom adapter not loading title array only 0's with Navigation Drawer

Im looking for someone that can help me with my Navigation Drawer with a customer list adapter. Im having a issue with my Listview not populating the String arrays and my list header strings and instead loading some sort of resource id number.
Im new to listviews and just need someone that is more familiar to look over the below code to help me figure out why this is happening.

and instead loading some sort of resource id number.
What you see is what you should get based on your code. First of all, for the big number(21... which is a string id from your code), you get this because in your getView() method you use:
holder.textHolder.setText(String.valueOf(item.title));
item.title is the id of the string resource and you can't just pas it around expecting to get the actual string, you need to convert it before using. This could be done using:
holder.textHolder.setText(getContext().getResources().getString(item.title));
For the rows with the 0 text, that's happening because you don't setup the non header rows properly. You have the strings in an string array resource, dashboard_array, but when you build the adapter's items you use a for loop with:
int id_title = getResources().getIdentifier(item, "string", this.getPackageName());
This will not work because you're looking for a string resource by a name that only exists in a string array resource(so there's no R.string.item_name_here) which will return 0, which you later insert as the text like you did for the header. So you either break that string array resources in 7 individual strings and use your current code(with the getIdentifier() method) or you change the way you handle the text for non header rows(to not use item.title for normal rows).
As a side note, you're not properly implementing the two types of rows for the ListView. The idea is to implement the getViewTypeCOunt and getItempViewType() methods and then use them in the getView() method to inflate and set the proper row type. There're a lot of example out there on how to do this.
