在Android 4.4奇巧，您可以设置状态栏和导航栏透明与安卓windowTranslucentStatus 和安卓windowTranslucentNavigation 主题元素，然后下面条的应用程序窗口，延长和梯度增加。然而在Android 5.0棒棒糖这已被改变，而不是现在梯度实心透明颜色被添加。安卓5.0提供了新的安卓statusBarColor 和安卓：在新材料主题navigationBarColor 元素，但是当你尝试设置这些元素 @android：彩色/透明应用程序窗口没有延长，而如果使用安卓windowTranslucentStatus 和安卓windowTranslucentNavigation 然后安卓statusBarColor 和安卓navigationBarColor 被忽略。

On Android 4.4 KitKat you can set the Status and Navigation bars transparent with the android:windowTranslucentStatus and android:windowTranslucentNavigation theme 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:statusBarColor and android:navigationBarColor elements under the new Material theme, but when you try to set these elements to @android:color/transparent the app window is not extended, and if you use android:windowTranslucentStatus and android:windowTranslucentNavigation then android:statusBarColor and android:navigationBarColor are ignored.

推荐答案

让安卓windowTranslucentStatus 的假的并置机器人：statusBarColor 为 @android：彩色/透明

然后添加code：

getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

如果你也想导航条是半透明的，集安卓navigationBarColor 到 @android：彩色/透明并结合标志 View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 和

If you also want navigation bar to be translucent, set android:navigationBarColor to @android:color/transparent and combine the flag View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION as well.

我没有尝试在导航栏上，但它的工作。

I didn't experimented on navigation bar but it will work.
