android set selector for textView

resource:

selector_text_white_gray.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item  android:state_pressed="true" android:color="@color/gray_color_2"></item>
    <item  android:state_pressed="false" android:color="@color/white"></item>

</selector>

Set properties for textView

 <TextView
            android:id="@+id/tv_right"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:focusable="true"
            android:clickable="true"
            android:textSize="@dimen/font_size2"
            android:textColor="@drawable/selector_text_white_gray" />

That'll be fine
