I created a button in the layout . In the Drawable folder I created a XML file named btn01_state . The btn01_state.xml is assigned to the button i created through " android:background=@drawable/btn01_state " Now, the button has a default image img1.when i click on the button , the image1 changes to img2, and once i release the clicked mouse button, the image2 again changed to img1 again. what i want to do is,to change the image of the button with evey click. for an example, initially btn01 has img01 if btn01 is pressed==> set img of btn01 to img02 and keep img02 till the btn01 is pressed again
