Change the tint of drawable in xml selector

问题

I have a button with the background defined in xml. I would like to tint the button based on the current state it is in - ie - pressed, focussed, normal.

Here is my xml file below. Also, my colored_tint_dark, and colored_tint are both translucent colors that I am trying to draw over the drawable image that I call from the resources folder. Here is the problem. When the UI first loads, the image has the appropriate tint on it, but after pressed, the pressed state doesn't show any tint, then the normal state won't show any tint.

<?xml version="1.0" encoding="utf-8"?>

<item android:state_pressed="true" android:drawable="@drawable/rounded_grayscale_pinstripe_button">
    <shape>
        <gradient
            android:endColor="@color/colored_tint"
            android:startColor="@color/colored_tint"
            android:angle="270" />
        <stroke
            android:width="0dp"
            android:color="@color/colored_tint" />
        <corners
            android:radius="0dp" />
        <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
    </shape>
</item>

<item android:state_focused="true" android:drawable="@drawable/rounded_grayscale_pinstripe_button">
    <shape>
        <gradient
            android:endColor="@color/colored_tint"
            android:startColor="@color/colored_tint"
            android:angle="270" />
        <stroke
            android:width="0dp"
            android:color="@color/colored_tint" />
        <corners
            android:radius="0dp" />
        <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
    </shape>
</item>

<item android:drawable="@drawable/rounded_grayscale_pinstripe_button">        
    <shape>
        <gradient
            android:endColor="@color/colored_tint_dark"
            android:startColor="@color/colored_tint_dark"
            android:angle="270" />
        <stroke
            android:width="0dp"
            android:color="@color/colored_tint_dark" />
        <corners
            android:radius="0dp" />
        <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
    </shape>
</item>

I know that there are solutions to this in java, but I am specifically looking for a solution in xml. Thanks.

Create a selector tint_menu_item.xml :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/white" android:state_pressed="true" />
    <item android:color="@color/white" android:state_activated="true" />
    <item android:color="@color/green" />
</selector>

(In my example, image is white when selected, and green when not selected)

Then in your xml, you can add tint attribute to ImageView:

<ImageView
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:tint="@color/tint_menu_item"
    android:src="@drawable/ic_menu_home" />

You can also use this selector on a TextView using textColor attibute:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="@color/tint_menu_item" />
