Android沉浸式状态栏实现

(1)沉浸式
在Activity或FragmentActivity中放入下面的代码
不需要在xml或sytyle中实现 android:fitsSystemWindows="true"代码

@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus && Build.VERSION.SDK_INT >= 19) {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}

(2)非沉浸式
不需要android:fitsSystemWindows="true"代码
不需要android:clipToPadding="true"
/**
* 状态栏透明
*/
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = getWindow();
window.setFlags(
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
