I want to detect each item in my RecylerView after it is displayed to the user.
Basically, I am trying to play a sound on each item after it is loaded on the screen.
But I am not able to detect whenever each item is loaded on the screen! Is there any method I have to call to detect each item rendered
E.g 1st RecyclerView item displayed -> play sound
2st RecyclerView item displayed -> play sound...
My Adapter class looks like this -
public class AdapterListAnimation extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<Multiples> items = new ArrayList<>();
private Context ctx;
private OnItemClickListener mOnItemClickListener;
private int animation_type = 0;
.........
.........
I am calling this initComponent()
method from onCreated()
method. Can you give advice on what should I do to achieve my goal as described above?
private void initComponent() {
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
items = DataGenerator.getPeopleData(this,of,value);
setAdapter();
/* MediaPlayer mp=MediaPlayer.create(this, R.raw.sword);
if (mp.isPlaying()) {
mp.stop();
mp.release();
mp = MediaPlayer.create(this, R.raw.sword);
} mp.start();*/
}
private void setAdapter() {
// Set data and list adapter
mAdapter = new AdapterListAnimation(this, items, animation_type);
recyclerView.setAdapter(mAdapter);
// on item list clicked
mAdapter.setOnItemClickListener(new AdapterListAnimation.OnItemClickListener() {
@Override
public void onItemClick(View view, com.math.multiplication.model.Multiples obj, int position) {
Snackbar.make(parent_view, "Item " + obj.first + " clicked", Snackbar.LENGTH_SHORT).show();
}
});
}
you need to override onViewAttachedToWindow
and onViewDetachedFromWindow
. but for detecting holer type you need getItemViewType()
just like that:
public class PostAdapter extends RecyclerView.Adapter {
@Override
public int getItemViewType(int position) {
switch (types.get(position)){
case 1:
return 1;
case 2:
return 2;
default:
return position;
}
}
@Override
public void onViewAttachedToWindow(@NonNull RecyclerView.ViewHolder holder) {
super.onViewAttachedToWindow(holder);
if (holder.getItemViewType() == 1){
//play song
}
}
@Override
public void onViewDetachedFromWindow(@NonNull RecyclerView.ViewHolder holder) {
super.onViewDetachedFromWindow(holder);
if (holder.getItemViewType() == 1){
//pause song
}
}
