Change navigation bar color, Android
提问by Marco Gagino
How can I change the color/transparency of the Navigation Bar from black to a generic color in pre-Lollipop devices (e.g. the color of the status bar or of the action bar)?
如何在 Lollipop 之前的设备中将导航栏的颜色/透明度从黑色更改为通用颜色（例如状态栏或操作栏的颜色）？
Can I do it using AppCompat or is it only possible for SDK 21?
我可以使用 AppCompat 来完成还是仅适用于 SDK 21？

You can set the attribute navigationBarColorin an AppCompat theme, or android:navigationBarColorin a native v21 theme.
您可以navigationBarColor在 AppCompat 主题或android:navigationBarColor原生 v21 主题中设置该属性。
<style name="AppTheme" parent="@style/Theme.AppCompat.Light">
...
<item name="navigationBarColor">#123456</item>
</style>

Note that this does not work on Pre-Lollipop devices, since this feature needs to be supported by the system, which is not the case on Android 4.4 or older.
请注意，这不适用于 Pre-Lollipop 设备，因为此功能需要系统支持，而在 Android 4.4 或更早版本上则不是这种情况。

Another programmatically way:
另一种编程方式：
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(getResources().getColor(R.color.DarkOrange));
window.setNavigationBarColor(getResources().getColor(R.color.red));
Further, to change your status bar color, add the following line:
此外，要更改状态栏颜色，请添加以下行：
window.setStatusBarColor(getResources().getColor(R.color.green));
