Two ways to implement animation effect

Note: This example is AlphaAnimation effect. As for other effects, just change the object.

1. .java file code control to add and start animation

//添加动画效果		AlphaAnimation animation = new AlphaAnimation(0.3f, 1.0f);		//设置次效果的持续时间		animation.setDuration(2000);		//设置动画的监听事件		animation.setAnimationListener(new AnimationListener() {			@Override			public void onAnimationStart(Animation animation) {				//动画开始监听事件				//do something...			}			@Override			public void onAnimationRepeat(Animation animation) {							}			@Override			public void onAnimationEnd(Animation animation) {				//动画结束监听事件				//do something...			}		});		//开始动画		view.startAnimation(animation);

2. .xml file code to load xml and start animation

alpha_out.xml Fade out effect

<?xml version="1.0" encoding="utf-8"?><!-- android:duration="@android:integer/config_mediumAnimTime" --><set xmlns:android="http://schemas.android.com/apk/res/android" ><alpha android:fromAlpha="1.0" android:toAlpha="0" android:duration="500"/> <!-- 透明度控制动画效果 alpha        浮点型值：        fromAlpha 属性为动画起始时透明度        toAlpha   属性为动画结束时透明度        说明:         0.0表示完全透明        1.0表示完全不透明                     以上值取0.0-1.0之间的float数据类型的数字                长整型值：        duration  属性为动画持续时间        说明:                          时间以毫秒为单位--></set>

Code loading xml:

Attributes:

private Animation anim;	private AnimationListener animLis;

Copy after login

Loading:

//初始化动画监听事件AnimationListener		animLis = new AnimationListener() {						@Override			public void onAnimationStart(Animation arg0) {				//动画开始监听事件				//do something...			}						@Override			public void onAnimationRepeat(Animation arg0) {			}						@Override			public void onAnimationEnd(Animation arg0) {				//动画结束监听事件				//do something...				tv.setVisibility(View.GONE);			}		};		//加载xml		anim = AnimationUtils.loadAnimation(this, R.anim.alpha_out);		//设置监听事件		anim.setAnimationListener(animLis);		//开始动画		tv.startAnimation(anim);
