How to reset back onItemClickListener to true after been set to null?

I have set onItemClickListener in my list view,items including videos, images and text. When user tap on the video in list view it plays fine. Now inside the method of playVideo() I set the listview to null so as the user should not interact with the video while playing.

I want to regain/reset back the onitemClicklisterner to true after the video finishes to play. How do I implement this, Kindly assist.

    private void playVideo() {
listOfMessages.setOnItemClickListener(null);
videoText.setVideoURI(Uri.parse(chattVideo));
frameText.setVisibility(View.VISIBLE);
imageVideo.setVisibility(View.INVISIBLE);
videoText.setVisibility(View.VISIBLE);
btnText.setVisibility(View.GONE);
try {
videoText.setMediaController(mediaControllerText);
mediaControllerText.show();
videoText.seekTo(1);
videoText.pause();
videoText.stopPlayback();
videoText.seekTo(1);
videoText.resume();
progressBarMessage.setVisibility(View.GONE);
videoText.start();
videoText.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
mp.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
progressBarMessage.setVisibility(View.GONE);
mp.start();
}
});
}
});
videoText.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
listOfMessages.setOnItemClickListener(this);// if I do like this android studio complains it cannot be applied inside MediaPlayer.OnCompletionListener
btnText.setVisibility(View.VISIBLE);
}
});
videoText.setOnErrorListener(new MediaPlayer.OnErrorListener() {
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
FancyToast.makeText(getContext(),"Something went wrong!",FancyToast.LENGTH_LONG,
FancyToast.ERROR,R.drawable.wheel,false).show();
return false;
}
});
} catch (Exception e) {
PBar.setVisibility(View.GONE);
FancyToast.makeText(getContext(),e.getMessage(),
FancyToast.LENGTH_LONG,FancyToast.WARNING,R.drawable.wheel,false).show();
}
}

You can create a method as below to do required stuff

Here is pseudo code

private void setListener(boolean isPlaying){
if(isPlaying){
your_listview.setOnItemClickListener(null);
}
else{
your_listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//YOUR CODE
}
});
}
}

Now,simply call setListener(true) when video plays or else
setListener(false)

I would use a boolean that you can set to true/false when the video is playing and depending on it's state the onClickListener can react differently.

Edit:

Or use button.setClickable(false); (has to be used after .setOnClickListener().

Or button.setEnabled(false); (this one can even be used before .setOnClickListener().

These two methods have the advantage that button animations get disabled too and they might work better if you have multiple clickable objects stacked on top of each other.
They are in the View class and can be called on a ListView too (but i didn't try that "live").

boolean isPlaying = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(isPlaying){
//do stuff
} else {
//do someting else
}
}
});
}
