如何通过代码检查android videoview是否支持文件? [英] How to check if file is supported by android videoview by code?

问题描述

我正在尝试通过Android videoview播放视频.这是我的代码:

I am trying to play video by Android videoview. Here is my code:

super.onCreate(savedInstanceState);
setContentView(R.layout.video);
VideoView videoView = (VideoView) findViewById(R.id.videoView);
videoView.setVideoURI(uri);
videoView.requestFocus();
videoView.start();

这可以正常工作，但是某些电话仍显示标题为无法播放视频"的对话框.

This works fine, however some phones still show dialog box with title "Cannot play video".

我的问题是如何禁用此通知窗口? 我的意思是，我可以在调用videoView.start()之前检查视频文件是否受支持吗?还是可以禁用或阻止调用系统弹出通知窗口?

My question is how to disable this notification window? I mean, can I check if the video file is supported or not before calling videoView.start()? Or can I disable or prevent calling the system popup notification window?

如果电话不支持，我想跳过视频，而没有通知窗口.

I would like to simply skip the video if not supported by the phone, without the notification window.

推荐答案

在启动VideoView之前，我使用setOnErrorListener来检查视频是否可以播放.

I used setOnErrorListener before you start the VideoView to check if video will play.

    // Restart if PROBLEM
    myVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {

        public boolean onError(MediaPlayer mp, int what, int extra) {
            // TODO Auto-generated method stub
            Intent intent = getIntent();
            overridePendingTransition(0, 0);
            intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

            finish();

            overridePendingTransition(0, 0);
            startActivity(intent);

            return true;
        }

    });
    myVideoView.start();
