android更改导航栏颜色

Question

我正在尝试更改工具栏的颜色，但我似乎无法找到合适的位置。以下是必要的文件和图片：

以下是样式，清单和java main。

Answer 1

您可以通过在样式

中添加此语句来实现

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

或主java中的这个

window.setNavigationBarColor(@ColorInt int color);

Answer 2

mDrawerLayout.setBackgroundResource(int);

如果您使用的是NavigationView，请选择提供此选项

 android:background="@color/color_navigation_list_background"
