1、需要在drawable文件夹下添加一组图片，并且写一个my_animation.xml的文件(内容如下)，其中false代表循环播放，duration代表帧的时间间隔

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="false">    <item android:drawable="@drawable/aa" android:duration="60"/>    <item android:drawable="@drawable/bb" android:duration="60"/>    <item android:drawable="@drawable/cc" android:duration="60"/>    <item android:drawable="@drawable/dd" android:duration="60"/>    <item android:drawable="@drawable/ee" android:duration="60"/>    <item android:drawable="@drawable/ff" android:duration="60"/>    <item android:drawable="@drawable/gg" android:duration="60"/>    <item android:drawable="@drawable/hh" android:duration="60"/></animation-list>

2、activity代码

package com.example.administrator.myanimation;import android.graphics.drawable.AnimationDrawable;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;import android.widget.ImageView;/** * Created by Administrator on 2015/11/20. */public class FrameAnimationActivity extends AppCompatActivity {    private Button mButtonStart;    private Button mButtonStop;    private ImageView mImageView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_frame);        mButtonStart = (Button) findViewById(R.id.button_start);        mButtonStop = (Button) findViewById(R.id.button_stop);        mImageView = (ImageView) findViewById(R.id.imageview);        final AnimationDrawable anim = (AnimationDrawable) mImageView.getBackground();        mButtonStart.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                anim.start();            }        });        mButtonStop.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                anim.stop();            }        });    }}

3、布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <Button        android:id="@+id/button_start"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="开始"/>    <Button        android:id="@+id/button_stop"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="结束"/>    <ImageView        android:id="@+id/imageview"        android:layout_width="70dp"        android:layout_height="100dp"        android:background="@drawable/my_animation"/></LinearLayout>
