You can also perform zoom in\u00a0and zoom out\u00a0separately, for that you will have to create another file in anim folder, and don’t write the ‘android:startOffset’ property in this file else it will start the zoom out\u00a0after some delay.<\/li>\n<\/ul>\nCode:<\/p>\n

Points to Remember: For creating the zoom.xml file you will have to first create anim folder under res folder. At the time of creating zoom.xml file you can either select ‘scale’ or ‘set’ as Root Element. You can also perform zoom in\u00a0and zoom out\u00a0separately, for that you will have to create another file in anim folder, and don’t write the ‘android:startOffset’ property in this file else it will start the zoom out\u00a0after some delay.
