带 VideoView 的无缝视频循环，无滞后

Question

在这个应用程序中，我们希望在观看时没有任何延迟地显示连续视频。每个视频的 uri 存储在一个数组中，我们通过循环显示这些视频，但视频和其他视频之间的演示存在延迟。如何解决这个问题？

public class ShowActivity extends AppCompatActivity {

VideoView video;
ProgressDialog pd;
int currentPlayingIndex = 0;

@Override
protected void onCreate( Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_show);
    video=findViewById(R.id.videoView);
    pd=new ProgressDialog(ShowActivity.this);

    Bundle b=getIntent().getExtras();
    String[] arrayresulturi=b.getStringArray("uriresult");

    video=findViewById(R.id.videoView);
    Uri uri = Uri.parse(arrayresulturi[0]);
    video.setVideoURI(uri);
    video.start();

    video.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mp) {
            currentPlayingIndex++;
            if (arrayresulturi[currentPlayingIndex] != null) {
                mp.setLooping(true);
                Uri uri = Uri.parse(arrayresulturi[currentPlayingIndex]);
                video.setVideoURI(uri);
                video.start();

            }// end if()
            else {
                video.stopPlayback();
                Intent backIntent = new Intent(ShowActivity.this,MainActivity.class);
                startActivity(backIntent);
            }//end else
        }//end onCompletion
    });//end setOnCompletionListener()
}//end onCreate()

}//结束类
