Animation of Android Development

1. Transparent Animation---alphaanimation

A. Dynamic Java code implements the transparency effect of button buttons

1Rootview.findviewbyid (r.id.btnanimation). Setonclicklistener (NewOnclicklistener () {2                 3 @Override4      Public voidOnClick (View v) {5     //TODO auto-generated Method Stub6Alphaanimation aa=NewAlphaanimation (0, 1);7Aa.setduration (1000);8 v.startanimation (AA);9 Ten         } One});

B. Implementing transparent animations with XML property settings

To create a new Android XML fils, on the new page, Resource type selected for tween animation,root element is selected as Alpha.

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <Alphaxmlns:android= "Http://schemas.android.com/apk/res/android"3 Android:fromalpha= "0"4 Android:toalpha= "1"5 android:duration= "+" >6 </Alpha>

Java code

1Rootview.findviewbyid (r.id.btnanimation). Setonclicklistener (NewOnclicklistener () {2                 3 @Override4                  Public voidOnClick (View v) {5                     //TODO auto-generated Method Stub6 v.setanimation (Animationutils.loadanimation (Getactivity (), R.ANIM.AA));7                 }8});
