Question

我使用自定义视频视图。但问题是我可以在我的应用程序中听到收音机但没有显示任何内容，只是黑屏。

所以我试着看日志，我得到了像

这样的错误

当我尝试连接该网站时，我可以获得.avi文件。它运作良好。

但我不知道我错过了什么..

我附上了我的.java和.xml来源。

.java来源

public class ExerciseFragment
    extends Fragment {
private String uri = null;
public MyVideoView videoView;
private WebService ws = new WebService();
private CustomMediaController localCustomMediaController = null;

public void onConfigurationChanged(Configuration paramConfiguration) {
    super.onConfigurationChanged(paramConfiguration);
    if (paramConfiguration.orientation == 2) {
        this.videoView.isFull = true;
    }
    while (paramConfiguration.orientation != 1) {
        return;
    }
    this.videoView.isFull = false;
}

public void onCreate(Bundle paramBundle) {
    super.onCreate(paramBundle);
    paramBundle = getArguments();
    if (paramBundle != null) {
        this.uri = paramBundle.getString("uri");
    }
}

@Nullable
public View onCreateView(LayoutInflater paramLayoutInflater, ViewGroup paramViewGroup, Bundle paramBundle) {
    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
    View view = paramLayoutInflater.inflate(R.layout.fragment_correct_exercise, paramViewGroup, false);

    return view;
}

private VideoView mVideoView;

public void onStart() {
    super.onStart();

    if (!User.logout) {
        this.ws.callSearchDialog(getActivity(), "조회중입니다.");
        this.videoView = ((MyVideoView) getActivity().findViewById(R.id.videoView));
        localCustomMediaController = new CustomMediaController(getActivity());
    }
    try {
        this.videoView.setVideoPath(this.uri);
        this.videoView.bringToFront();
        this.videoView.setMediaController(localCustomMediaController);
        this.videoView.requestFocus();
        this.videoView.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer paramAnonymousMediaPlayer) {
                ExerciseFragment.this.videoView.seekTo(2);
                ExerciseFragment.this.ws.removeSearchDialog();
            }
        });
    } catch (Exception localException) {
        localException.printStackTrace();
        this.ws.removeSearchDialog();
    }
    ExerciseFragment.this.ws.removeSearchDialog();

}

public void onStop() {
    super.onStop();
}

class CustomMediaController extends MediaController {
    ImageButton mCCBtn;
    Context mContext;

    public CustomMediaController(Context context) {
        super(context);
        this.mContext = context;
    }

    private View makeCCView() {
        this.mCCBtn = new ImageButton(this.mContext);
        this.mCCBtn.setImageResource(R.drawable.icon_fullscreen_24);
        this.mCCBtn.setBackgroundColor(0);
        this.mCCBtn.setOnClickListener(new OnClickListener() {
            public void onClick(View paramAnonymousView) {
                paramAnonymousView = ExerciseFragment.this.videoView;
                if (ExerciseFragment.this.videoView.isFull) { // isFull =
                    ExerciseFragment.this.videoView.isFull = false;
                } else {
                    ExerciseFragment.this.videoView.isFull = true;
                }
                ExerciseFragment.this.videoView.requestLayout();
            }
        });
        return this.mCCBtn;
    }

    public void setAnchorView(View paramView) {
        super.setAnchorView(paramView);
        FrameLayout.LayoutParams frameParams = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        frameParams.gravity = Gravity.RIGHT | Gravity.TOP;
        addView(makeCCView(), frameParams);
    }
}

和.xml源

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rl_exercise"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<MyVideoView
    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true" />

更新

这是MyVideoView.java

public class MyVideoView  extends VideoView
{
  public boolean isFull = false;

  public MyVideoView(Context paramContext, AttributeSet paramAttributeSet)
  {
    super(paramContext, paramAttributeSet);
  }

  public void onMeasure(int paramInt1, int paramInt2)
  {
    if (this.isFull)
    {
      ((WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
      setMeasuredDimension(paramInt1, paramInt2);
      return;
    }
    setMeasuredDimension(BaseActivity.displayWidth, BaseActivity.displayHeight/2);
  }
}

是的，请有人帮助我。感谢

Android Videoview，我的应用程序中缺少什么？
