自定义videoview实现全屏播放

最近的项目中需要横屏播放视频的功能，本来是想通过设置videoview宽高的方式来实现，不过后来发现效果不佳，遂决定自定义一个videoview来解决这个问题。

代码如下：

自定义view:

package com.sac.widget;

import android.R.integer;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class MyVideoView extends VideoView {

    public MyVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        // TODO Auto-generated constructor stub
    }

    public MyVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public MyVideoView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }
    @Override
    protected void onMeasure(int widthMeasureSpec,int heightMeasureSpec){
        int width = getDefaultSize(0, widthMeasureSpec);
        int height = getDefaultSize(0, heightMeasureSpec);
        setMeasuredDimension(height, width);
    }

}

 if(getRequestedOrientation()!=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE){
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
     }
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);

        width = dm.widthPixels;
        height = dm.heightPixels;
        Log.v("width", width+"");
        Log.v("height", height+"");

        LayoutParams lp = videoView.getLayoutParams();
        lp.width = height;
        lp.height = width;

        videoView.setLayoutParams(lp);

这样就大功告成了
