 requestWindowFeature(Window.FEATURE_NO_TITLE);   //设置activity 显示没有标题
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,//全屏显示
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        width = this.getWindowManager().getDefaultDisplay().getWidth(); //得到宽高
  height = this.getWindowManager().getDefaultDisplay().getHeight();
隐藏状态栏代码：     getWindow().setFlags(WindowManager.LayoutParams.TYPE_STATUS_BAR,                                    WindowManager.LayoutParams.TYPE_STATUS_BAR);requestWindowFeature(Window.FEATURE_NO_TITLE);   
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,    
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
