how to rotate an image back and forth in android without using animation
<p>i want to create a car dashboard on android.Actually i am created already this application.But that is based on animation and it is working nicely.Now here i want to add two button(up and down).when i am clicking up the hand have to move 10 degree up.Again click up button means the hand have to move 10 degree up from the current position, and when i am clicking down means it have to come down by 10 degree. i cant do this by a single button in animation.in animation i want to create more button and each button i want to create different animation. This is very complex. please somebody help me to do this.Here i am adding my code</p>
