推荐答案

可以在styles.xml中使用

<item name="android:navigationBarColor">@color/theme_color</item>

或

window.setNavigationBarColor(@ColorInt int color)

http://developer.android.com/reference/android/view/Window.html#setNavigationBarColor(int)

请注意，该方法是在 Android Lollipop 中引入的，不适用于 API 版本 <21.

Note that the method was introduced in Android Lollipop and won't work on API version < 21.

第二种方法(适用于 KitKat)是在清单中将 windowTranslucentNavigation 设置为 true 并在导航栏下方放置一个彩色视图.

The second method (works on KitKat) is to set windowTranslucentNavigation to true in the manifest and place a colored view beneath the navigation bar.
