步奏三:敲代码

/**
    	 * 播放视频
    	 */
    	private void initVideView(){
    		//播放路径
    		loginVv.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.video));
    		//播放
    		loginVv.start();
    		//循环播放
    		loginVv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    			@Override
    			public void onCompletion(MediaPlayer mediaPlayer) {
    				loginVv.start();
    			}
    		});
    	}
    	@Override
    	protected void onRestart() {
    		//返回重新加载
    		initVideView();
    		super.onRestart();
    	}
    
    
    	@Override
    	protected void onStop() {
    		//防止锁屏或者弹出的时候，音乐在播放
    		loginVv.stopPlayback();
    		super.onStop();
    	}

运行看结果

### 视频做背景也不麻烦 ###

步奏1:  
重写视频view

import android.content.Context;
    import android.support.annotation.NonNull;
    import android.support.annotation.Nullable;
    import android.support.v4.view.ViewPager;
    import android.util.AttributeSet;
    import android.view.MotionEvent;
    
    /**
     * @author 红叶岭谷
     * 自定义ViewPager
     */
    public class LGvideoview extends VideoView {
    	public CustomVideoView(Context context) {
            super(context);
        }
    
        public CustomVideoView(Context context, AttributeSet attrs) {
            super(context, attrs);
        }
    
        public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
            super(context, attrs, defStyleAttr);
        }
    
        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
            //我们重新计算高度
            int width = getDefaultSize(0, widthMeasureSpec);
            int height = getDefaultSize(0, heightMeasureSpec);
            setMeasuredDimension(width, height);
        }
        @Override
        public void setOnPreparedListener(MediaPlayer.OnPreparedListener l) {
            super.setOnPreparedListener(l);
        }
    
        @Override
        public boolean onKeyDown(int keyCode, KeyEvent event) {
            return super.onKeyDown(keyCode, event);
        }
    }

步骤二:写xml文件

<com.changda.mst.lmts.viewfragment.viewadapter.LGvideoview
            android:id="@+id/login_vv"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

步奏三:写代码
