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

1、连续动画（动画监听器实现）

Animation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate);//先旋转
            donghua_image.startAnimation(loadAnimation);
            final Animation loadAnimation_2 = AnimationUtils.loadAnimation(this, R.anim.scale);//后缩放
            
            //动画监听器
            loadAnimation.setAnimationListener(new AnimationListener() {
                
                @Override
                public void onAnimationStart(Animation arg0) {
                    // TODO Auto-generated method stub
                    
                }
                
                @Override
                public void onAnimationRepeat(Animation arg0) {
                    // TODO Auto-generated method stub
                    
                }
                //结束后的操作
                @Override
                public void onAnimationEnd(Animation arg0) {
                    // TODO Auto-generated method stub
                    donghua_image.startAnimation(loadAnimation_2);
                }
            });

效果图：

2、连续动画（配置文件实现）

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

对应的配置文件

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <alpha    //先20%透明到100%透明，持续三秒
        android:duration="3000"
        android:fromAlpha="0.2"
        android:toAlpha="1.0" />
    <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
        android:duration="3000"
        android:fromAlpha="1.0"
        android:startOffset="3000"
        android:toAlpha="0.2" />

</set>

效果图：

3、闪烁动画效果

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