推荐答案

首先，声明进度对话框

private static ProgressDialog progressDialog;

那么，在的onCreate，呼吁runOnUiThread之前，启动对话框

Then, in onCreate, before calling runOnUiThread, start the dialog

progressDialog = ProgressDialog.show(this, "", "Loading...", true);

在的playVideo，设置在preparedListener，将关闭该对话框当视频是准备玩

In playVideo, set a OnPreparedListener that will dismiss the dialog when the video is ready to play

mVideoView.setOnPreparedListener(new OnPreparedListener() {

    public void onPrepared(MediaPlayer arg0) {
        progressDialog.dismiss();
        mVideoView.start();
    }
});
