设置为null后，如何将onItemClickListener重置为true？

我在列表视图中设置了onItemClickListener，其中包括视频，图像和文本。当用户在列表视图中点击视频时，它可以正常播放。现在，在playVideo（）方法内部，将listview设置为null，以便用户在播放时不应与视频进行交互。

我想重获/ RESE丁字裤的onitemClicklisterner到真正的视频结束播放后。我该如何实施，请协助。

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();
    }

}
