- 去除安卓系统顶部状态栏：
requestWindowFeature一定要在setContentView之前调用：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
}
- 去除app标题栏
在activity的样式里加入：
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
