Demo:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
getWindow().getDecorView().setSystemUiVisibility(View.INVISIBLE);
}
else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
// this.requestWindowFeature(Window.f);// 去掉标题栏
// this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
// WindowManager.LayoutParams.FLAG_FULLSCREEN);// 去掉信息栏
Log.i("info", "portrait"); // 竖屏
}
Need:
<uses-sdk android:minSdkVersion="11" />

View类提供了setSystemUiVisibility和getSystemUiVisibility方法,这两个方法实现对状态栏的动态显示或隐藏的操作,以及获取状态栏当前可见性。
setSystemUiVisibility(int visibility)方法可传入的实参为:
1. View.SYSTEM_UI_FLAG_VISIBLE:显示状态栏,Activity不全屏显示(恢复到有状态的正常情况)。
2. View.INVISIBLE:隐藏状态栏,同时Activity会伸展全屏显示。
3. View.SYSTEM_UI_FLAG_FULLSCREEN:Activity全屏显示,且状态栏被隐藏覆盖掉。
4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN:Activity全屏显示,但状态栏不会被隐藏覆盖,状态栏依然可见,Activity顶端布局部分会被状态遮住。
5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION:效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
6. View.SYSTEM_UI_LAYOUT_FLAGS:效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION:隐藏虚拟按键(导航栏)。有些手机会用虚拟按键来代替物理按键。
8. View.SYSTEM_UI_FLAG_LOW_PROFILE:状态栏显示处于低能显示状态(low profile模式),状态栏上一些图标显示会被隐藏。
