        Uri mVideoURI = data.getData();

Answer 1

您必须让 videoview 从添加videoview.start();. 代码：

public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (resultCode != RESULT_OK) return;

    if (requestCode == PICK_FROM_GALLERY) {
        Uri mVideoURI = data.getData();  
        videoView.setVideoURI(mVideoURI);
        videoview.start();   //edited
    }

}
