The only image for all button states for Android?

I have an image for my button. In order to make use of it I have to have 1 additional image for each state: 1. disabled 2. selected 3. pressed etc..

in iOS all those additional states are handled automatically and deferred from original image provided.

Is it possible to accomplish this for Android?

This answer refers to how you can handle button states in Android You can create a button layout file separately in put that in res > layout folder

For Instance:

if the layout file name is btn.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="@drawable/btn_pressed" />   
  <item android:drawable="@drawable/btn_normal"/> 

</selector>

You can set BackgroundResource of a Button

yourButton.setBackgroundResource(R.layout.btn);

EDIT

In addition you can refer to this link which is more closer to answer your question

As far as I know you need to handle this states in a new resource file called cursor: e.g:

<selector xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/edittext_selector" android:layout_height="fill_parent"
    android:layout_width="fill_parent">
    <!-- Image display in background in select state -->
    <item
       android:state_pressed="true"
       android:drawable="@drawable/edittextback1">
    </item>

    <!-- Image display in background in select state -->
    <item
        android:state_enabled="true"
        android:state_focused="true"
        android:drawable="@drawable/edittextback2">
    </item>

    <!-- Default state -->
    <!--<item android:state_enabled="true"-->
        <!--android:drawable="@drawable/your_ninepath_image">-->
    <!--</item>-->
</selector>

No, It is NOT. You need to have all states's images with you to define the selector

You can define button_selector.xml

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


    <!-- Selected state -->
    <item android:drawable="@drawable/button_bg_selected" android:state_selected="true"></item>

    <!-- Pressed  state -->
    <item android:drawable="@drawable/button_bg_pressed" android:state_pressed="true"></item>

     <!-- Disabled   state -->
    <item android:drawable="@drawable/button_bg_disabled" android:state_enabled="false"></item>

    <!-- Normal state -->
    <item android:drawable="@drawable/button_bg_normal"></item>



</selector>

Then simply assign this selector as a background of a button 

<Button
     android:id="@+id/button1"
     android:background="@drawable/button_selector"
     android:layout_width="200dp"
     android:layout_height="126dp"
     android:text="Hello" />

Refer : Button Selector

Hope it will help you ツ

You will have to use selector for android.

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

 android:background="@drawable/selector_button" />

just have a look of this link.

For selected and pressed you can use an xml file with root for button's background but for disabled I guess you need to handle it in java code. I'm not sure about disabled state.
