AlertDialog Builder inside holder.itemView.setOnClickListener onBindViewHolder

I wish did fix the issue. I believe your problem is that you have not called show() on your AlertDialog.Builder instance. I don't see anything wrong with your Context argument.
This is the last line of the builder:
code :
}).setNegativeButton("No",null);
}).setNegativeButton("No",null)
.show();

onBindViewHolder(RecyclerView.ViewHolder holder, int position) - can't access holder's 'fun' - Kotlin to Java


By : Yugi

I hope this helps . I have 2 classes for RecyclerView - Adapter and ViewHolder. In Adapter class which is written in Kotlin I'm implementing onBindViewHolder(RecyclerView.ViewHolder holder, int position) method and I am able to access holder.bind() - fun - easly but when I try to remake this Kotlin file to Java file and access holder.bind() it is not possible. How can I access holder.bind() from Java file? , Replace
code :
if(itemRepo != null){
   holder.bind(itemRepo) // not possible
}
if (itemRepo != null && holder instanceof RepoViewHolder) {
   ((RepoViewHolder) holder).bind(itemRepo)
}

Access all holder views inside OnBindViewHolder in RecyclerView

I think the issue was by ths following , You cannot do that due to the way RecyclerView lazy load the child view. The child views are only created and rendered when they are visible on the screen, other views are cleared to save memory.
You can do these to have the same effect:
code :
<FrameLayout>
    <RecyclerView ... />

    <FrameLayout
        android:id="@+id/overlay_view" 
        ...
        android:clickable="true" />
</FrameLayout>

cardItem.setOnClickListener(view -> {
    // The mOverlayView will intercept all the touch event on RecyclerView
    mOverlayView.setVisibility(View.VISIBLE);
})

wish helps you There is no way you are calling notify datasetchanged on the adapted to let it know to update the list after you have deleted the code. I wouldn't want to put a code like this on recycler view adapter's onbindviewholder() function. Make function in your activity to delete the entry from db, once it is deleted call notifydatasetchanged on the adapter. Don't forget to call this on main thread when you return from a background thread for db. Make an interface and pass I'd of item to be deleted from the adapter to the activity and write the delete logic there.
Update:
code :
public interface MyInterface{
   public void foo(int deleteThisId);
}
public class MyActivity extends Activity implements MyInterface{

//Somewhere in on create where you init the adapter
    adapter = MyAdapter(this); // where this is the instance for the interface which will be used in adapter

    public void foo(int deleteThisId){
        //do stuff with deleteThisId
        //when finished with delete operation 
        adapter.notifyDatasetChanged();
    }
public MyAdapter extends RecyclerView.Adapter<>{
private MyInterface listener;

public MyAdapter(MyInterface listener){
    this.listener = listener;
}
}
listener.foo(idToBeDeleted);

Cannot open fragment when click on itemView on holder

I hope this helps you . I trying to use fragment instead of activity as much as possible, in my custom adapter PostAdapter I use holder.itemView.setOnClickListener method to pass and open DetailsFragment at the end, but when I click on any item on recyclerView it's not doing anything , Solved
The cause of the problem in this line
code :
fragmentTransaction.replace(R.id.nav_view,detailsFragment);
fragmentTransaction.replace(R.id.parentLayout,detailsFragment);

How do I implement the holder.itemView.setOnClickListener from the UserAdapter in a fragment?

will help you Generally in this case, just having a boolean in the constructor of the adapter will do the job. Let's say your isFragment boolean is used for this. So follow button visibility just set to GONE if isFragment is true and when clicking on "Go to user's profile" button just do this:
code :
if (isFragment)
    return
