沉浸式状态栏

声明：这不是Google官方说的Immersive Full-Screen Mode，而是大家习惯说的Translucent screen。
onCreate方法里添加如下代码：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR| WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE); getWindow().setStatusBarColor(Color.TRANSPARENT); } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); }
注意 ：此时要将apptheme设置成
<style name="AppBaseTheme" parent="android:Theme.Material.Light">
