视频播放火力四射

Question

我已经使用Fire base数据库存储了视频链接，总共有3个链接。并可以连续播放视频，而无需触摸代码，前提是您可以演示如何连续播放歌曲。对不起，代码也可能会出错。

private FirebaseDatabase firebaseDatabase;
private DatabaseReference song1;
private DatabaseReference song2;
private DatabaseReference song3;
private VideoView videoView;



protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
  firebaseDatabase = FirebaseDatabase.getInstance();
  song1 = firebaseDatabase.getReference().child("Song").child("1");
  song2 = firebaseDatabase.getReference().child("Song").child("2");
  song3 = firebaseDatabase.getReference().child("Song").child("3");
  videoView = findViewById(R.id.videoView);
  total = firebaseDatabase.getReference().child("Song");
------------------------------------------------------------------------

  total.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            List<Uri> list = new ArrayList<>();
            for (DataSnapshot child : dataSnapshot.getChildren()) {
                list.add(child.getValue(Uri.class));
                Uri uri=Uri.parse(dataSnapshot.getValue().toString());
               videoView.setVideoURI(uri);
               videoView.requestFocus();
               videoView.start();
            }



}

Answer 1

videoView.setOnPreparedListener(new OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mplayer) {
        mplayer.setLooping(true);
    }
});

您可以创建一个方法并将不同的URL传递给它。

playVideo(String uri) {

    videoView.setVideoURI(uri);
    videoView.requestFocus();
    videoView.start();
}

并在调用playVideo方法时检查以下情况-

if (videoView.isPlaying()) {

}
else {
     playVideo(uri);
}
