<?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/image_click" /> <item android:state_focused="true" android:drawable="@drawable/image_focused" /> <item android:drawable="@drawable/image_click" /> </selector>
“@drawable/BasicImage” is default image. “@drawable/onClickImage”is focused image. BasicImage and onClickImage exist at /res/drawable/, too. add source to /res/layout/main.xml (main view layout file)
<ImageView android:id="@+id/id" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/image_effect" android:onClick="main_OnClick" />
