How to set image button backgroundimage for different state?

I want imagebutton with two states i) normal ii) touch(or click).

I have set normal image in the imagebutton background and I am trying to change image(pressed) from onclick method, but it doesn't change.

I want that if I pressed image button then image should change from normal to pressed until I press other button but it doesn't happen.

Can anyone suggest to me how can I do this with selector or at run time?

Here is my imagebuttonpanel code.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="horizontal"
  android:gravity="bottom"
  android:id="@+id/buttonpanel">
  <ImageButton android:id="@+id/buttonhome"
               android:layout_width="80dp"
               android:layout_height="36dp"
               android:focusable="true" 
               android:background="@drawable/homeselector">
               </ImageButton>
  <ImageButton android:id="@+id/buttonsearch"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/searchselector"
               android:focusable="true">
               </ImageButton>>
  <ImageButton android:id="@+id/buttonreg"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/registerselector"
               android:focusable="true">
               </ImageButton>>
  <ImageButton android:id="@+id/buttonlogin"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/loginselector"
               android:focusable="true">
               </ImageButton>
</LinearLayout>

and my selector xml is

<?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/homehover" 
        /> <item android:state_focused="true" android:drawable="@drawable/homehover" 
        /> <item android:drawable="@drawable/home" /> <item android:state_window_focused="true" 
        android:drawable="@drawable/homehover" /> -->
    <item android:state_enabled="false" android:drawable="@drawable/homehover" />
    <item android:state_pressed="true" android:state_enabled="true"
        android:drawable="@drawable/homehover" />
    <item android:state_focused="true" android:state_enabled="true"
        android:drawable="@drawable/homehover" />
    <item android:state_enabled="true" android:drawable="@drawable/home" />

</selector> 

And I have also tried to change image resource on ontouch and onclick event, but it does not help.

Solution 1:

Create an xml file in your drawable like this :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_enabled="false"
        android:drawable="@drawable/btn_sendemail_disable" />
    <item
        android:state_pressed="true"
        android:state_enabled="true"
        android:drawable="@drawable/btn_send_email_click" />
    <item
        android:state_focused="true"
        android:state_enabled="true"
        android:drawable="@drawable/btn_sendemail_roll" />
    <item
        android:state_enabled="true"
        android:drawable="@drawable/btn_sendemail" />
</selector>

And set images accordingly and then set this xml as background of your imageButton.

Solution 2:

Try this

btn.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        btn.setBackgroundResource(R.drawable.icon);
    }
});

Solution 3:

mhh. I got another solution which helped me, 'cause I just have two different sates:

• either the item is not clicked
• or it is clicked and so it will be highlighted

In my .xml I define the ImageButton like this:

 <ImageButton
    android:id="@+id/imageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/selector" />

The corresponding selector file looks like this:

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

    <item android:drawable="@drawable/ico_100_checked" android:state_selected="true"/>
    <item android:drawable="@drawable/ico_100_unchecked"/>

</selector>

And in my onCreate I call:

final ImageButton ib = (ImageButton) value.findViewById(R.id.imageButton);

    OnClickListener ocl =new OnClickListener() {
        @Override
        public void onClick(View button) {
            if (button.isSelected()){
                button.setSelected(false);
            } else {
                ib.setSelected(false);
                //put all the other buttons you might want to disable here...
                button.setSelected(true);
            }
        }
    };

ib.setOnClickListener(ocl);
//add ocl to all the other buttons

done. hope this helps. took me a while to figure out.
