自定义View 全屏显示的问题

Question

只要Activity为全屏，让自定义的view的长宽是当前分辩率就好了，

Answer 1

在onCreate里面调用下面这两个函数：
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);然后把ListView的width、height设置为fill_parent

Answer 2

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//隐藏标题栏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);//隐藏状态栏
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
screenWidth = metrics.widthPixels;//获取屏幕宽高
screenHeight = metrics.heightPixels;
setContentView(R.layout.main);
}
这样就全屏了
