Android button select and press drawable

Question

I'm trying to make a button with state press and select, I already did the same with tabs and it works but I don't know why here does not work. I have done it like this:

button_sel.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"         android:shape="rectangle">     <gradient android:startColor="@color/azulado"                android:endColor="@color/azulBrillante"               android:angle="270" />      <corners android:radius="@dimen/corner_radius" />      <stroke android:width="2px"               android:color="@color/blanco" />  </shape> 

button_unsel.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"         android:shape="rectangle">     <gradient android:startColor="@color/botonesD"                android:endColor="@color/botones"               android:angle="270" />     <corners android:radius="@dimen/corner_radius" />     <stroke android:width="2px"              android:color="@color/blanco" /> </shape> 

And the selector, button.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:drawable="@drawable/button_sel"             android:state_selected="true"            android:state_pressed="true"/> <item android:drawable="@drawable/button_unsel"        android:state_selected="false"        android:state_pressed="false"/> </selector> 

And here I call the drawable as a background:

 <style name="button">     <item name="android:background">@drawable/button</item>     <item name="android:textSize">@dimen/text_size</item>     <item name="android:padding">@dimen/padding_button</item>     <item name="android:textColor">@color/blanco</item>  </style> 

Thank you!!!!

The first item in your selector is only used, when the button is pressed AND selected. If you want to use button_sel when your button is pressed OR selected, you should do something like this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:drawable="@drawable/button_sel" android:state_selected="true" />     <item android:drawable="@drawable/button_sel" android:state_pressed="true" />     <item android:drawable="@drawable/button_unsel" /> </selector> 

The items are evaluated from top to bottom, the last one is the default. Though I am not sure if state_selected makes sense for buttons.
