Question

Hi i want to set selector to image through code. I have a selector which diff images for diff image view state . There is a way to set selector through xml file but i want to set it on button click .

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

My Code is :-

img.setImageResource(R.layout.my_button);

Or there is any way to change image on focus/hover in android?

Please suggest me usable link or sample code.

Answer 1

This selector depends on view’s state.
For example set this view focused:

myView.requestFocusFromTouch();

and the first item with state_focused="true" will be used.

If you want to switch drawables programmaticaly then use Level List:
