android 沉浸式状态栏

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}

或

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}

SetContentView 之前调用

或者

设置主题

<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<!-- API 19 theme customizations can go here. -->
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>

二者都要布局设置否则布局可能位移

layout.setFitsSystemWindows(true);
layout.setClipToPadding(true);
