Android 4.4 translucent Status and Navigation bars style on Android 5.0
提问by AxeEffect
On Android 4.4 KitKat you can set the Status and Navigation bars transparent with the android:windowTranslucentStatusand android:windowTranslucentNavigationtheme elements, and then below the bars the app window is extended and a gradient is added. However on Android 5.0 Lollipop this has been changed and now instead of the gradient a solid transparent color is added. Android 5.0 offers the new android:statusBarColorand android:navigationBarColorelements under the new Material theme, but when you try to set these elements to @android:color/transparentthe app window is not extended, and if you use android:windowTranslucentStatusand android:windowTranslucentNavigationthen android:statusBarColorand android:navigationBarColorare ignored.
在 Android 4.4 KitKat 上，您可以使用android:windowTranslucentStatus和android:windowTranslucentNavigation主题元素将状态栏和导航栏设置为透明，然后在栏下方扩展应用程序窗口并添加渐变。然而，在 Android 5.0 Lollipop 上，这已被更改，现在添加了纯透明颜色而不是渐变。Android 5.0在新的Material 主题下提供了new android:statusBarColorandandroid:navigationBarColor元素，但是当你尝试将这些元素设置到@android:color/transparentapp 窗口时是不会扩展的，如果你使用android:windowTranslucentStatusand android:windowTranslucentNavigationthen android:statusBarColorand 都会android:navigationBarColor被忽略。
Am I missing something described on http://developer.android.com/training/material/theme.html#StatusBar?
我是否遗漏了http://developer.android.com/training/material/theme.html#StatusBar 上描述的内容？

Set android:windowTranslucentStatusto falseand set android:statusBarColorto @android:color/transparent.
设置android:windowTranslucentStatus为false并设置android:statusBarColor为@android:color/transparent。
Then add code below:
然后在下面添加代码：
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
If you also want the navigation bar to be translucent, set android:navigationBarColorto @android:color/transparentand combine the flag View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATIONas well.
如果您还希望导航栏是半透明的，也可以设置android:navigationBarColor为@android:color/transparent并组合标志View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION。
I didn't experiment on the navigation bar but it will work.
我没有在导航栏上进行实验，但它会起作用。

To clarify @suckgamony's answerto this question:
澄清@suckgamony对这个问题的回答：
- Under Lollipop and above, setting
android:statusBarColororandroid:navigationBarColorto@android:color/transparentwill make the Status Baror Navigation Bar(respectively) completely transparent, unless: android:windowTranslucentStatusorandroid:windowTranslucentNavigationis set to true, in which case the Status Baror Navigation Bar(respectively) is set to the solid transparent color @AxeEffect describes (again, under Lollipop and above);android:statusBarColorandandroid:navigationBarColormay only be used with Android version 21 (Lollipop 5.0) or higher. As described in the referred to answer,android:windowTranslucentStatusorandroid:windowTranslucentNavigationwhen used with Kitkat provide transparent gradients rather than full transparency.
- 下棒棒糖和上面，设置
android:statusBarColor或android:navigationBarColor以@android:color/transparent将使状态栏或导航栏（分别）是完全透明的，除非： android:windowTranslucentStatus或android:windowTranslucentNavigation设置为 true，在这种情况下，状态栏或导航栏（分别）设置为@AxeEffect 描述的纯透明颜色（同样，在 Lollipop 及以上）；android:statusBarColor并且android:navigationBarColor只能与 Android 版本 21 (Lollipop 5.0) 或更高版本一起使用。如参考答案中所述，android:windowTranslucentStatus或android:windowTranslucentNavigation与 Kitkat 一起使用时提供透明渐变而不是完全透明。
