android 如何去掉状态栏和标题栏

修改对应的Activity，添加以下代码：

final Window win = getWindow();

 win.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

 WindowManager.LayoutParams.FLAG_FULLSCREEN); //remove statusbar

 requestWindowFeature(Window.FEATURE_NO_TITLE);

 requestWindowFeature(Window.FEATURE_PROGRESS); //remove titlebar

注意：必须添加在setContentView()方法之前，否则将提示错误。
