Question

我有3个视频。取决于videoLong我使用videoView播放所选视频。

我有两个问题：

第一次播放视频时，它有效。视频会在正确的时间停止，并使用finish()。但是在doInBackground之后的任何时间都没有检查其他if语句。

我的onPostExecute永远不会被调用。

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (videoLong == 0) {
    videoView
            .setVideoURI(Uri
                    .parse("http://pv...70ab1aae7633.mp4"));
    videoView.seekTo(60000 * 10);// 10 mins
    videoView.start();
    new myAsync().execute();
} else if (videoLong == 1) {

    videoView
            .setVideoURI(Uri
                    .parse("http://pv....mp4"));
    videoView.seekTo(60000 * 10);// 10 mins
    videoView.start();
    new myAsync().execute();
} else if (videoLong == 2) {
    videoView
            .setVideoURI(Uri
                    .parse("http://pv....mp4"));
    videoView.seekTo(60000 * 10);// 10 mins

    new myAsync().execute();
    videoView.start();
}
}

private class myAsync extends AsyncTask<Void, Integer, Void> {

int duration = 0;
int current = 0;

protected void onPreExecute() {
    super.onPreExecute();
    System.out.println("on pre execute");
    // alertDialog = new AlertDialog.Builder(PlayVideoActivity.this);
}

@Override
protected Void doInBackground(Void... params) {

    videoView
            .setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

                public void onPrepared(MediaPlayer mp) {
                    duration = videoView.getDuration();

                }
            });

    videoView
            .setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                public void onCompletion(MediaPlayer mp) {
                    // Do whatever u need to do here
                    System.out.println("video complete");
                    finish();
                }
            });

    do {
        current = videoView.getCurrentPosition();
        // System.out.println("duration - " + duration + " current- " +
        // current);

        try {

            publishProgress((int) (current * 100 / duration));

            // System.out.println("time: " + current);
            if (current >= 610100 && videoLong == 0) {
                System.out.println("video 1 done");
                videoView.stopPlayback();

                videoView = null;
            }
            if (current >= 610200 && videoLong == 1) {
                System.out.println("video 2 done");
                videoView.stopPlayback();
                finish();
            }
            if (current >= 610200 && videoLong == 2) {
                System.out.println("video 3 done");
                videoView.stopPlayback();
                finish();
            }
            if (mProgressBar.getProgress() >= 100) {
                // System.out.println("error100");
            }

        } catch (Exception e) {
            // e.printStackTrace();
        }
    } while (mProgressBar.getProgress() <= 100);

    return null;
}

@Override
protected void onProgressUpdate(Integer... values) {
    super.onProgressUpdate(values);
    // System.out.println("values: " + values[0]);
    mProgressBar.setProgress(values[0]);
}

@Override
protected void onPostExecute(Void result) {
    System.out.println("on POST execute");


}

}

@Override
 public void onBackPressed() {
if (videoView != null)
    videoView.stopPlayback();
videoView = null;
System.out.println("back button pressed. stop playback");
super.onBackPressed();
}

感谢您的期待！

android - videoView只执行一次AsyncTask / onPostExecute永远不会被调用
