Question

我想在Android导航抽屉中设置自定义PNG图像。但默认情况下它显示为灰色。当我尝试设置自定义图像时，它会自动更改为灰色，但它会着色。

有人能建议我解决这个问题吗？

Answer 1

在菜单项中添加色调。

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:id="@+id/logout"
    android:iconTint="#464641"
    android:icon="@drawable/ic_exit_to_app_black_24dp"
    android:title="Logout"/>

activity_main.xml中

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
