android - DialogFragment 中的 VideoView

Question

我刚刚创建了一个自定义的 DialogFragment，里面有一个 VideoView，但我遇到了一些问题。

• 视频正在播放，但是不知为何，视频的顶部有一层黑色的透明层。当然，我尝试从我的应用程序中的其他地方播放相同的视频，这不是对话窗口，但它显示正确。很奇怪...

• 此外，对话框窗口的顶部和左侧边框消失了 - 如果移除 VideoView，它们也不会消失。

有什么想法吗？提前致谢!

Controller

public class VideoPlayerFragment extends DialogFragment
{
    String json_string;

    // Constructor
    public static VideoPlayerFragment newInstance(String json_string_arg)
    {
        VideoPlayerFragment fragment = new VideoPlayerFragment();

        Bundle arguments = new Bundle();
        arguments.putString("json_string", json_string_arg);
        fragment.setArguments(arguments);

        return fragment;
    }


    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Set style
        setStyle(DialogFragment.STYLE_NO_TITLE, 0);
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.video_player, container, false);

        return view;
    }


    @Override
    public void onActivityCreated(Bundle savedInstanceState)
    {
         super.onActivityCreated(savedInstanceState);

         // Set video holder
         VideoView video_view = (VideoView) getView().findViewById(R.id.video_view);

         // Set URL
         Uri video = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.test);
         video_view.setVideoURI(video);

         // Start video
         video_view.start();
    }
}

     public class VideoPlayerFragment extends DialogFragment
        {
            String json_string;

            // Constructor
            public static VideoPlayerFragment newInstance(String json_string_arg)
            {
                VideoPlayerFragment fragment = new VideoPlayerFragment();

                Bundle arguments = new Bundle();
                arguments.putString("json_string", json_string_arg);
                fragment.setArguments(arguments);

                return fragment;
            }

        @Override
            public Dialog onCreateDialog(Bundle savedInstanceState) {
                Dialog dialog = new Dialog(getActivity());
                dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
                dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
                dialog.getWindow().setSoftInputMode(
                        WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN|WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
                dialog.setCancelable(true);
                View parent= getActivity().getLayoutInflater().inflate(R.layout.video_player, null);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
dialog.setContentView(parent, layoutParams);
                return dialog;
            }
         @Override
            public void onActivityCreated(Bundle savedInstanceState)
            {
                 super.onActivityCreated(savedInstanceState);

                 // Set video holder
                 VideoView video_view = (VideoView) getView().findViewById(R.id.video_view);

                 // Set URL
                 Uri video = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.test);
                 video_view.setVideoURI(video);

                 // Start video
                 video_view.start();
            }

friend 试试上面的代码。不要创建 View ，而是尝试创建没有对话框标题的 onCreateDialog ....
