Question

I am new to android development, can any one tell me how to rotate entire a button into 45 degrees along with text and button rect. I want to rotate permanently and i want on click listener on the same.

Answer 1

You need to use animations for that.

in your /res/anim/ you must create an xml file with this:

<?xml version="1.0" encoding="utf-8"?>
<rotate
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:fromDegrees="0"
  android:toDegrees="45"
  android:pivotX="50%"
  android:pivotY="50%"
  android:duration="0"
  android:startOffset="0"
/>

and the in your Activity:

RotateAnimation ranim = (RotateAnimation)AnimationUtils.loadAnimation(this, R.anim.YOUR_ANIM);
ranim.setFillAfter(true);
YourButton.setAnimation(ranim);

Apart from that it seems that there are some problems with diagonal rotations (a.k.a. 45 degrees) pre-honeycomb..
