Android中VideoView视频的全屏和半屏的切换

private boolean fullscreen=false;if(!fullscreen){//设置RelativeLayout的全屏模式
       RelativeLayout.LayoutParams layoutParams=
              new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
           mVideoView01.setLayoutParams(layoutParams);

           fullscreen = true;//改变全屏/窗口的标记
       }else{//设置RelativeLayout的窗口模式
          RelativeLayout.LayoutParams lp=new  RelativeLayout.LayoutParams(320,240);
          lp.addRule(RelativeLayout.CENTER_IN_PARENT);
            mVideoView01.setLayoutParams(lp);
            fullscreen = false;//改变全屏/窗口的标记

    }

 

 

　　　在oncreate方法之前调用

  //去掉头信息
        requestWindowFeature(Window.FEATURE_NO_TITLE);
         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                    WindowManager.LayoutParams.FLAG_FULLSCREEN)

//判断手机屏幕的方向
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        width=dm.widthPixels;
        heigh=dm.heightPixels;
        if(width/heigh>0)
        {
            //横屏
            path = bundle.getString("widthurl");

        }
        if(width/heigh==0)
        {
            //竖屏
            path = bundle.getString("heighturl");

        }

第二种方法

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

public class MyVideoView extends VideoView {

    public MyVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public MyVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyVideoView(Context context) {
        super(context);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // TODO Auto-generated method stub

        int width = getDefaultSize(0, widthMeasureSpec);
        int height = getDefaultSize(0, heightMeasureSpec);
        setMeasuredDimension(width, height);
    }

}

</FrameLayout>
------------全屏的设置
if(!fullscreen){//设置RelativeLayout的全屏模式
       RelativeLayout.LayoutParams layoutParams=
              new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
           layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
           mVideoView01.setLayoutParams(layoutParams);

           fullscreen = true;//改变全屏/窗口的标记
       }else{//设置RelativeLayout的窗口模式
          RelativeLayout.LayoutParams lp=new  RelativeLayout.LayoutParams(320,240);
          lp.addRule(RelativeLayout.CENTER_IN_PARENT);
            mVideoView01.setLayoutParams(lp);
            fullscreen = false;//改变全屏/窗口的标记
       }
