Selector for button error "Valid XML document must have a root tag"

Question

I have three image for Button, using png format.

I have made a Selector as below:

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

<!-- pressed -->
<item android:state_pressed="true" android:drawable="@drawable/press_pdgmap" />

<!-- hover -->
<item android:state_focused="true" android:drawable="@drawable/hover_pdgmap2" />

<!-- default -->
<item android:drawable="@drawable/hover_pdgmap" />

</selector>

But red tag appear in line pressed, hover, and default, it says

Top level element is not completed, Valid XML document must have a root tag

note: I'm using Android Studio

You forgot to put <selector> node as parent. [Check this][1] [1]: stackoverflow.com/questions/14023886/android-button-selector — Tabrej Khan

Then you should have mentioned that to begin with. Have you tried cleaning and rebuilding your project since making that change? — codeMagic

Top level element should be selector and XML file should be placed in the res/drawable/ directory. Example:

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

I have moved selector to top like example, and xml file already placed in res/drawable folder, but still got red tag @Vadim

If your xml is the same as in example and placed in the right folder then everything should work. Try to run gradle clean task. Maybe file name or xml contains illegal characters?

@Ade06 also I have tried to copy your xml to Android Studio project (with my drawables) and it's working fine. XML in your example is valid selector.
