1：然后在drawable 里面创建一个rootElement为animation-list的文件drawable_elec，

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"><item android:drawable="@mipmap/elec01" android:duration="200"/><item android:drawable="@mipmap/elec02" android:duration="200"/><item android:drawable="@mipmap/elec03" android:duration="200"/><item android:drawable="@mipmap/elec04" android:duration="200"/><item android:drawable="@mipmap/elec05" android:duration="200"/></animation-list>

2：布局里面：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <ImageView        android:layout_marginBottom="100dp"        android:layout_alignParentBottom="true"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/drawable_elec"        android:id="@+id/animationList"/>    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:onClick="animationList"        android:text="start/stop"/></RelativeLayout>

2：MainActivity 里面：

package tech.androidstudio.animationdemo;import android.graphics.drawable.AnimationDrawable;import android.graphics.drawable.Drawable;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.view.animation.TranslateAnimation;import android.widget.ImageView;import android.widget.TextView;public class MainActivity extends AppCompatActivity implements Animation.AnimationListener {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void animationList(View view) {        ImageView animationList = (ImageView) findViewById(R.id.animationList);        AnimationDrawable animationDrawable = (AnimationDrawable)animationList.getDrawable();        if(!animationDrawable.isRunning())            animationDrawable.start();        else            animationDrawable.stop();    }}
