To implement a color filter using XML, you can use the following steps:

1. Define a color filter in your res/color folder. For example, create color_filter.xml with the following code:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#FFAABBCC" />
</selector>

1. In your layout file, add an ImageView and set its src attribute:

<ImageView
    android:id="@+id/my_image_view"
    android:src="@drawable/my_image" />

1. Apply the color filter to the ImageView using the android:tint attribute and reference the color filter defined in color_filter.xml:

<ImageView
    android:id="@+id/my_image_view"
    android:src="@drawable/my_image"
    android:tint="@color/color_filter" />

1. Run your app and the ImageView with the color filter should be displayed.

Note: You can also use the android:tintMode attribute to specify the blending mode for the color filter. The default is src_in which multiplies the source color with the tint color. Other modes include src_over, dst_over, multiply, and screen.
