I would like to change the background color of my ImageButton on pressed event.
Here is what i am done :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="@color/rose_normal" />
<solid
android:state_pressed="true"
android:color="@color/rose_fonce" />
<stroke
android:width="1sp"
android:color="@color/rose_fonce" />
</shape>
My button is well in "rose_normal" color, but never in "rose_fonce" color on press.
Where is the problem ?
EDIT : PROBLEM SOLVED :
Create one xml file called background_rounded_button.xml :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/rounded_button_rose_fonce" android:state_selected="true"></item>
<item android:drawable="@drawable/rounded_button_rose_fonce" android:state_pressed="true"></item>
<item android:drawable="@drawable/rounded_button_rose_normal"></item>
</selector>
rounded_button_rose_fonce.xml :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="@color/rose_fonce" />
<stroke
android:width="1sp"
android:color="@color/rose_fonce" />
</shape>
rounded_button_rose_normal.xml :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="@color/rose_normal" />
<stroke
android:width="1sp"
android:color="@color/rose_fonce" />
</shape>
And finally, apply background for the button :
<ImageButton
android:id="@+id/all_annonce_button_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="10dp"
android:layout_marginRight="10dp"
android:background="@drawable/background_rounded_button.xml"
android:padding="16dp"
android:src="@drawable/ic_action_search" />
The problem is that you are not using a selector, but a shape.
Try this code (button_selector.xml, put it in your drawable folder):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/rose_fonce" android:state_selected="true"></item>
<item android:drawable="@color/rose_fonce" android:state_pressed="true"></item>
<item android:drawable="@color/rose_normal"></item>
</selector>
When setting this selector as the background of a Button, it will have the "rose_normal" color in normal state, and the "rose_fonce" color when pressed or selected.
Example:
<Button
android:background="@drawable/button_selector" />
