android animation through button
<p>I am creating a dash board application. This is what it looks like:<br>
<img src="http://i.stack.imgur.com/sX7co.png" alt="enter image description here"> </p>

<p>Now I will explain to you how it is working. When I am clicking the "UP" button the red hand moves up and stay in the 30. The "DOWN" button is used for down the hand from 30 to 0. The BUTTON5 is used for moving the hand from 0 (starting position) to 5. When I am clicking BUTTON10 it means it will move from 5 to 10. BUTTON-5 is used for down the hand from 10 to 5 and BUTTON0 is used for down the hand from 5 to 0.</p>

<p>This is my code:</p>

import android.graphics.Bitmap;

<p>Now I want to add a button "+" instead of button5 and button10 (for increment) and "-" for the button-5 and 0. How can I do the increment by a single button. I don't know how to do this. Here for rotating I am using animation. This is the xml code for rotation. Anybody know how to do this means just tell me.</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false"&gt;
    &lt;rotate android:toYScale="0.0" 
        android:pivotX="50%" 
        android:pivotY="50%" 
        android:duration="3599" 
        android:fromDegrees="0" 
        android:toDegrees="205"&gt;
     &lt;/rotate&gt;
&lt;/set&gt;
</code></pre>
