Button properties changes doesn't save after screen rotate

Question

I have a button which when pressed gets bigger and changes text color, but when the screen rotates, the button loses the new properties (size and text color). How can I make it save? Here's the code for the button

public void changeColor(View view) {
    Button button2 = (Button) findViewById(R.id.button2);
    button2.setTextColor(Color.CYAN);
    button2.setTextSize(50);
}

in the button XML I have given it ID, and onClick

In your manifest.xml write

android:configChanges="keyboardHidden|orientation"

Example

<activity
      android:name=".MainAct"
      android:configChanges="keyboardHidden|orientation" >
</activity>

awesome thanks, though I don't even knew about this thing. Is this the standart way to set things not change when rotate? – Sartheris Stormhammer Apr 27 '13 at 12:48
but why keyboardhidden? most android phones are without keyboards, shouldn't it be something like screenorientation? – Sartheris Stormhammer Apr 27 '13 at 12:54

you can read this doc http://developer.android.com/guide/topics/manifest/activity-element.html and you can vote up too – Ronak Mehta Apr 27 '13 at 13:21

After the screen rotation your app is started again new. So you can for example ignore screen rotation (How to make an application ignore screen orientation change?) or store your values after buton pressing in shared preferences and call them after screen rotation
