  • 安卓开发_浅谈Android动画（二）

    在学习了四个基本动画之后，现在要学习一些更有用的效果

    先给出所有的动画xml

 4     <alpha
 5         android:duration="3000"

12         android:toAlpha="0.2" />
13 
14 </set>
    continue_anim.xml //连续动画

    1、连续动画（动画监听器实现）

     1 Animation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate);//先旋转
 2             donghua_image.startAnimation(loadAnimation);
 3             final Animation loadAnimation_2 = AnimationUtils.loadAnimation(this, R.anim.scale);//后缩放
 4             
 5             //动画监听器
 6             loadAnimation.setAnimationListener(new AnimationListener() {
 7                 
 8                 @Override
 9                 public void onAnimationStart(Animation arg0) {
10                     // TODO Auto-generated method stub
11                     
12                 }
13                 
14                 @Override
15                 public void onAnimationRepeat(Animation arg0) {
16                     // TODO Auto-generated method stub
17                     
18                 }
19                 //结束后的操作
20                 @Override
21                 public void onAnimationEnd(Animation arg0) {
22                     // TODO Auto-generated method stub
23                     donghua_image.startAnimation(loadAnimation_2);
24                 }
25             });

    效果图：

    2、连续动画（配置文件实现）

    1 loadAnimation = AnimationUtils.loadAnimation(this, R.anim.continue_anim);
2             donghua_image.startAnimation(loadAnimation);

    对应的配置文件

     1 <?xml version="1.0" encoding="utf-8"?>
 2 <set xmlns:android="http://schemas.android.com/apk/res/android" >
 3 
 4     <alpha    //先20%透明到100%透明，持续三秒
 5         android:duration="3000"
 6         android:fromAlpha="0.2"
 7         android:toAlpha="1.0" />
 8     <alpha     //后100%透明到20%透明，持续三秒，从3秒后开始实现，即第一个动画实现完成后再实现
 9         android:duration="3000"
10         android:fromAlpha="1.0"
11         android:startOffset="3000"
12         android:toAlpha="0.2" />
13 
14 </set>

    效果图：

    3、闪烁动画效果

    1 　　　　　　//循环播放透明度动画实现闪烁效果
2             //JAVA代码实现
3             AlphaAnimation alpha = new AlphaAnimation(0.1f, 1.0f);
4             alpha.setDuration(100);//每次0.1秒内执行完动画
5             alpha.setRepeatCount(10); //执行10次动画
6             //重复方式。倒序Animation.REVERSE，正序Animation.START
7             alpha.setRepeatMode(Animation.REVERSE);
8             donghua_image.startAnimation(alpha);

    效果图：

    4、activity切换动画

    使用overridePendingTransition方法
    参数：第二个activity进入动画
    第一个activity退出动画

    在startActivity(intent);之后使用

    效果图：
