I am using the lists of audio on my Recyclview and it is working correct means I am able to play the audio file on my Recyclview.
As i am using the Seekbar with my audio file on my Recyclview , the problem is generating that when i am scrolling the Recyclview the other items's of Recyclview Seekbar is changing (Seekbar i am using for the progress of the audio file play.)
What i want that other Seekbar item of Recyclview sholud not be change when i scroll the Recyclview
Please check my code for it ,Inside the onBindViewHolder for my Recyclview , i am using the following code, please check it once.
((MyAudioChat) holder).sbMyAudio.setTag(position);
((MyAudioChat) holder).imgPlayAudio.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
((MyAudioChat) holder).sbMyAudio.removeCallbacks(null);
((MyAudioChat) holder).sbMyAudio.setProgress(0);
if (mediaPlayer == null) {
mediaPlayer();
((MyAudioChat) holder).sbMyAudio.setMax(mediaPlayer.getDuration());
} else {
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer();
((MyAudioChat) holder).sbMyAudio.setMax(mediaPlayer.getDuration());
}
((MyAudioChat) holder).sbMyAudio.getTag();
((MyAudioChat) holder).sbMyAudio.setMax(mediaPlayer.getDuration()); // Set the Maximum range of the
((MyAudioChat) holder).sbMyAudio.setProgress(mediaPlayer.getCurrentPosition());// set current progress to song's
Runnable moveSeekBarThread = new Runnable() {
public void run() {
if (mediaPlayer.isPlaying()) {
int mediaPos_new = mediaPlayer.getCurrentPosition();
int mediaMax_new = mediaPlayer.getDuration();
((MyAudioChat) holder).sbMyAudio.setMax(mediaMax_new);
((MyAudioChat) holder).sbMyAudio.setProgress(mediaPos_new);
((MyAudioChat) holder).sbMyAudio.postDelayed(this, 100); //Looping the thread after 0.1 second
((MyAudioChat) holder).sbMyAudio.getTag();
}
}
};
((MyAudioChat) holder).sbMyAudio.removeCallbacks(moveSeekBarThread);
((MyAudioChat) holder).sbMyAudio.postDelayed(moveSeekBarThread, 100);
}
});
I have visited the following site on SO but did not get the relevant solution
1 .First Link
2. Second Link
Can we use the setTag() and getTag() to get rid of from this problem. I have used the setTag() on my above code. Please check it once.
Although, you have asked only about correct SeekBar updates, I am assuming (because you haven't shard complete source) that soon you will face following issues which are linked to the Adapter implementation:
MediaPlayer completes the playback of audio?MediaPlayer when activity is paused?View.OnClickListeners and Runnables are being allocated on every onBindViewHolder call. How do I minimize their unnecessary allocation?You can find complete working solution here - GitHub
Following source tries to fix all above issues. Certain data structures/classes are assumed based on your nomenclature.
public class MainActivity extends Activity {
private MediaPlayer mediaPlayer;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView rv = (RecyclerView) findViewById(R.id.rv);
rv.setLayoutManager(new LinearLayoutManager(this));
AudioChat audioChats[] = new AudioChat[128];
rv.setAdapter(new MyAdapter(Arrays.asList(audioChats)));
}
@Override

super.onPause();
if (null != mediaPlayer) {
mediaPlayer.release();
mediaPlayer = null;
}
}

seekBarUpdater = new SeekBarUpdater();

return new MyAudioChat(LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false));
}
@Override

if (position == currentPlayingPosition) {
seekBarUpdater.playingHolder = holder;
holder.sbMyAudio.post(seekBarUpdater);

holder.sbMyAudio.setProgress(0);
