Resize video to fit the VideoView

2020-02-07 19:01发布

问题:

I'm positioning a VideoView with AbsoluteLayout (I need to display it on several places into the screen at specific positions).

public void showVideo(RectF bounds, final String videoUrl) {
    AbsoluteLayout.LayoutParams params = (AbsoluteLayout.LayoutParams) video.getLayoutParams();
    params.width = (int) bounds.width();
    params.height = (int) bounds.height();
    params.x = (int) bounds.left;
    params.y = (int) bounds.top;

    video.requestLayout();

    video.setVisibility(View.VISIBLE);
    video.setFocusable(true);
    video.setFocusableInTouchMode(true);
    video.requestFocus();

    File file = new File(videoUrl);
    video.setVideoPath(file.getAbsolutePath());
    video.start();
}

But the Video ins't getting resized to the bounds I specified.

Any tips?

回答1:

this is very close to what you are trying. if you are willing to subclass the videoview and override onMeasure here is the solution. you need to

MyVideoView extends VideoView

as for showing MediaController over VidowView

Declare

private MediaController controller = null;

OnCreate

controller = new MediaController(this);
controller.setMediaPlayer(mcEvents);
controller.setAnchorView(findViewById(R.id.wrapper));

Activity

@Override
public boolean onTouchEvent(MotionEvent event) {
    //the MediaController will hide after 3 seconds - tap the screen to make it appear again
    controller.show();
    return false;
}

Media Controller events

private MediaController.MediaPlayerControl mcEvents = new MediaController.MediaPlayerControl() {        
    public void start() {
        player.start();
    }

    public void seekTo(int pos) {
        player.seekTo(pos);         
    }

    public void pause() {
        player.pause();
    }

    public boolean isPlaying() {            
        return player.isPlaying();
    }

    public int getDuration() {          
        return player.getDuration();
    }

    public int getCurrentPosition() {           
        return player.getCurrentPosition();
    }

    public int getBufferPercentage() {          
        return pBuffer;
    }

    public boolean canSeekForward() {           
        return true;
    }

    public boolean canSeekBackward() {
        return true;
    }

    public boolean canPause() {
        return true;
    }
};

a sample layout file

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/wrapper"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<com.my.views.MyViedoView
    android:id="@+id/player"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
/>
</FrameLayout>

You can only change the layout file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <VideoView android:id="@+id/videoViewRelative"
         android:layout_alignParentTop="true"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_alignParentRight="true"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

After you change your LayoutParams I think you will need to call setLayoutParams so the layout can be updated with the new params. After the call to setLayoutParams you may have to call the method reqestLayout to invalidate the layout and trigger a redraw of the view.

You will need to create a new instance of the MediaController and use the method setMediaController on the VideoView object.
