Changing TextView background color on click

I have a TextView whose background I would like to change when clicked on. I've tried following the many examples of this I've found on this site and others, but I can't seem to get it working properly.

I'm completely new to android development, so it's quite possible that I'm missing something obvious, so please bear with me. I'm also trying to do this through XML as opposed to Java.

Main.xml (contained within a table layout)

<TextView
            android:id="@+id/character_option1"
            android:text="Option1" 
            android:textColor="@color/text_off"
            android:background="@drawable/selectors"
            android:clickable="true"
            android:padding="5dp" />

selectors.xml (in res/drawable)

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

colors.xml (in res/values)

<drawable name="option_on">#EBEBEB</drawable>
<drawable name="option_off">#CC0000</drawable>

I've also tried android:color="@color/option_off" in selectors.xml with color name="option_off" in res/values. And I tried simply putting android:color="#CC0000" right into selectors.xml. None of it worked.

I'm not sure it's receiving any information from the selector in general. I set the default color to red #CC0000 just to check, but the background color is still the style's default white.

To change View background color on click

in res/drawable/my_onclick_background.xml: 

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

then in res/values/colors.xml:

<?xml version="1.0" encoding="utf-8"?><resources>
<color name="colorPrimary">#008577</color>
<color name="colorPrimaryDark">#00574B</color>
<color name="colorAccent">#D81B60</color>

Put in your View's xml 

android:background="@drawable/my_onclick_background"

And you are done.

When specifying a drawable for a background

android:background="@drawable/selectors"

the item selectors in selectors.xml requires you to have the drawable attribute set.

You're setting the color attribute which won't work.

Instead change color to drawable.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true"
        android:drawable="@drawable/option_on">
    </item>
    <item
        android:drawable="@drawable/option_off" >
    </item>
</selector>

Here's a reference. Refer to the item tag section.

android:drawable
   Drawable resource. Required. Reference to a drawable resource.
