I want to Increase and decrease value of qty on clicked.
i Used ImageView for decrease and Increase the value in middle i used TextView for showing the value.
this thing is completely work in the Activity but i want perform this operation in ListView.
Here the complete code and it is working on simple Activity.
qty.java
public class qty extends AppCompatActivity {
int minteger = 0;
ImageView decrease;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.raw_order);
decrease=(ImageView) findViewById(R.id.decrease);
decrease.setEnabled(false);
}
public void increaseInteger(View view) {
minteger = minteger + 1;
display(minteger);
}public void decreaseInteger(View view) {
minteger = minteger - 1;
display(minteger);
}
private void display(int number) {
TextView displayInteger = (TextView) findViewById(
R.id.integer_number);
displayInteger.setText("" + number);
}
}
raw_order.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/decrease"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:src="#drawable/minus"
android:layout_marginTop="05dp"
android:textColor="#000"
android:onClick="decreaseInteger"
/>
<TextView
android:id="#+id/integer_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:textStyle="bold"
android:layout_marginTop="16dp"
android:textSize="20dp" />
<ImageView
android:id="#+id/increase"
android:layout_marginTop="05dp"
android:layout_width="30dp"
android:onClick="increaseInteger"
android:layout_height="wrap_content"
android:src="#drawable/plus"
android:textColor="#000"/>
</LinearLayout>
And i want to perform this same thing in ListView

count++;
resultp.put(cout);
displayInteger.setText("" + count);
}
});
return convertView;
}
private class SparseIntarray {
public SparseIntarray(int size) {
}
}
}
you can use SparseIntArray to store the value count for each position
in the listAdapter class define an instance variable
SparseIntArray sia; // class variable
.. inside listAdapter constructor
sia = new SparseIntArray(data.size());
then in OnClick event
public void onItemClick(...) {
int count = sia.get(position)
// now increment or decrement as per your requirement
// coutn++; or count--; and save it
sia.put(position, count);
Edit 1:
set OnClick listeners to your increase decrease imageViews in the getView() method,
final displayInteger = (TextView) convertView.findViewById(R.id.integer_number);
increase.setOnClikcListener(new OnClickListener {
#Override
public void onClick(View view)
{
int count = sia.get(position);
count++;
sia.put(position, count);
displayInteger.setText("" + count);
});
you can do the same with your decrease view
Make an OnLickListener for the image view and call the methods,
For the list view you need to make an OnItemSelectedListener Or OnItemClickListener
First You Need To Give The ImageView an ID; Then Do It Like This
In On Create :::
ImageView img=(ImageView)findViewById(R.id.imageview);
img.setOnClickListener(imgclick);
Then In The Class Body ::::
OnClickListener imgclick=new OnClickListener() {
#Override
public void onClick(View view) {
//Call The Methods Like Increase Number Or Decrease
}
};

You are applying differente adapters to the same recyclerview, which means the last one that will be visible will be the last one.
You can see it here:
CustomAdapter adapterf = new CustomAdapter(this, items);
firstrecyclerView.setAdapter(adapterf);
final YoutubeVideoAdapter adapter = new YoutubeVideoAdapter(this, youtubeVideoArrayList);
firstrecyclerView.setAdapter(adapter);
If you notice, you are doing firstrecyclerView.setAdapter(adapterf) where you attach the CustomAdapter. Then, you do again firstrecyclerView.setAdapter(adapter) where you attach the YoutubeVideoAdapter. Only the last adapter will take place, since it overrides the previous one.
EDIT:
As I can understand, you want to render a view where you display an YoutubeThumbnail and a TextView underneath that thumbnail. In your CustomAdapter, you are using a list of itemModel. Consider adding an attribute to that itemModel that holds the Youtube video URL. If you do it this way, you can show the thumbnail and the TextView at the same time, you just need to modify your CustomAdapter to the same as your YoutubeVideoAdapter.
I.e:
Your ItemModel would look like this:
public class itemModel {
String name;
String youtubeUrl;
public itemoModel(String name, String youtubeUrl){
this.name = name;
this.youtubeUrl = youtubeUrl;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getYoutubeUrl(){
return this.youtubeUrl;
}
public void setYoutubeUrl(String youtubeUrl){
this.youtubeUrl = youtubeUrl;
}
}
And your CustomAdapter:
public class viewHolder extends RecyclerView.ViewHolder {
public TextView iconName;
public YouTubeThumbnailView thumbnail;
public viewHolder(View itemView) {
super(itemView);
this.iconName = itemView.findViewById(R.id.icon_name);
this.thumbnail = itemView.findViewById(R.id.video_thumbnail_image_view);
}
}
#Override
public void onBindViewHolder(viewHolder holder, int position) {
TextView iconName =holder.iconName;
holder.iconName.setText(items.get(position).getName());
YouTubeThumbnailView thumbnail = holder.thumbnail;
String youtubeUrl = items.get(position).getYoutubeUrl();
//Do what you need to do with the youtubeUrl
}
This way you just need to use one adapter and one recyclerView with the code you've already done here:
CustomAdapter adapterf = new CustomAdapter(this, items);
firstrecyclerView.setAdapter(adapterf);
Let me know if it helped you!
i have tried several methods to make my items clickable i have read about focus and added the lines in my XML file Relative layout. nothing seems to help. the click listener still doesn't seem to do anything for me.. please help!!!

that is because yout did not start the activity
list1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long Id) {
Intent intent = new Intent(AdminList.this, LaunchActivity.class);

}
});
I have a RecyclerView that gets inflated in a Fragment. The problem is, when the items count gets more than views height, every item that is in the view will get a width of highest content (I mean all will get wrap content of highest width). In the image it's more specific, also after scrolling those views that will get refreshed will have a correct width (match parent). I already have tried those code suggestions on other questions but still problem exists. here is my code:
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.complex_item, parent, false);
return new ViewHolder(itemView);
}
The xml layout for items:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="wrap_content"
android:layout_margin="5dp"
android:id="#+id/baseBg"
android:orientation="vertical">
<LinearLayout
android:id="#+id/expand_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/list_item_background"
android:foreground="?selectableItemBackground"
android:gravity="center|right"
android:orientation="vertical"
android:padding="10dp">
<TextView
android:id="#+id/textViewTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:textColor="#color/colorPage5"
android:textSize="20sp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
Code snippet that does the fragment replace:
mainPageFrameLayout.removeAllViews();
FragmentTransaction ft =
getSupportFragmentManager().beginTransaction();
ft.replace(R.id.mainPageFrameLayout, new MojtamaFragment(id, "3"));
ft.commit();
And the mainPageFrameLayout:
<FrameLayout
android:id="#+id/mainPageFrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:animateLayoutChanges="true"
android:background="#color/colorPage5" />
The adapter and the onCreateView:
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.recycler_view_fragment, container, false);
final RecyclerView recyclerView = rootView.findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
...
//(this part items is getting generated by a Http Request)
...
recyclerView.setAdapter(new SimpleAdapter(recyclerView, id, title, getActivity(), complexID,MojtamaFragment.this));
return rootView;
}
Images:
Edit: Image explanation: as you can see in image 1 when items numbers gets more than views height items width gets wrap_content instead of match_parent (Image 2 is the correct one that it should be) in image 3 as you can see after i did scroll, items that get's re-instantiated gets correct width. I hope you get the point.

After so much editing and experiencing i found a part of code from my xml layout (the one that FrameLayout is in it and fragment gets replaced by it) has something to do with error:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.ahrabi.ojekavir.CityActivity"
tools:showIn="#layout/activity_city">
after removing app:layout_behavior and changing ContraintLayout to some Linear or RelativeLayout problem now is gone.
I don't know why this part raises such problem, but it has definitely a reason.

You just need a context, so:
Toast.makeText(rootView.getContext(), "Like is done.",
Toast.LENGTH_LONG).show();
But you need to make rootView final first:
public static ViewHolder create(final RelativeLayout rootView){...

And here is row_book.xml which is what the list objects should look like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="75dp">
<ImageView
android:id="#+id/img_thumbnail"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="25dp"
android:layout_centerVertical="true"
android:scaleType="centerInside"/>
<TextView
android:id="#+id/text_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/img_thumbnail"
android:layout_alignTop="#+id/img_thumbnail"
android:layout_marginLeft="25dp"/>
<TextView
android:id="#+id/text_author"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/text_title"
android:layout_alignLeft="#+id/text_title"/>
</RelativeLayout>
Thank you. I hope we can figure out why the list is not updating.
In DetailActivity.Java you need to declare variable like this
TextView myTextView;
Then inside the onCreate method you need to add this
String bookTitle = this.getIntent().getExtras().getString("bookTitle");
Still inside onCreate method you need to check if there is valid bookTitle
if (bookTitle.length() > 0) {
myTextView = (TextView) findViewById(R.id.text_title);
myTextView.setText(String.valueOf(bookTitle));
}
In activity_detail.xml the only thing that was missing on your xml file is
'android:text="#string/textview"' at the top
Change this to look something like below. Have it in mind that you will need to edit layout position to suits your app.
<TextView
android:text="#string/textview"
android:id="#+id/text_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="25dp"/>
The book title should now show up. Follow the same procedure to display the author name. I hope this helps.
