王学岗属性动画上(十)——使用xml文件配置多个动画(2)

一：布局文件，布局文件只有一个<ImageVIew/> 略去不提

二：看动画xml文件

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

    <objectAnimator  android:duration="5000" android:propertyName="scaleX" android:valueFrom="0.0" android:valueto="1.0" android:valueType="floatType" />
    <objectAnimator  android:duration="5000" android:propertyName="scaleY" android:valueFrom="0.0" android:valueto="1.0" android:valueType="floatType" />

</set>

MainActivity

package com.example.seven;

import android.animation.Animator;
import android.animation.AnimatorInflater;
import android.animation.AnimatorSet;
import android.animation.ObjectAnimator;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
@SuppressLint("NewApi")
public class MainActivity extends Activity {

    private ImageView iv_zhangxin;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv_zhangxin = (ImageView) findViewById(R.id.iv_zhangxin);
        MyClick mc = new MyClick();
        iv_zhangxin.setonClickListener(mc);
    }

    private class MyClick implements OnClickListener {
        @Override
        public void onClick(View v) {
            //AnimatorInflater：动画加载器，功能类似布局加载器
     Animator animator= AnimatorInflater.loadAnimator(MainActivity.this,R.animator.animator_set_x_y);
      animator.setDuration(5000);
      animator.setTarget(iv_zhangxin);
      animator.start();
        }

    }
}

十和十一大体相差不多，只有动画的xml文件有所改变
