下面例子混合使用了逐帧动画和补间动画，还有一个缺点，就是画面闪烁，一直没有找到解决办法

上面点击ImageView,上面的人物就开始走路跟移动

定义动画文件

<?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/one" android:duration="10" />   <item android:drawable="@drawable/two" android:duration="10" />   <item android:drawable="@drawable/three" android:duration="10" />   <item android:drawable="@drawable/four" android:duration="10" />   <item android:drawable="@drawable/five" android:duration="10" />   <item android:drawable="@drawable/six" android:duration="10" />   <item android:drawable="@drawable/seven" android:duration="10" />   <item android:drawable="@drawable/eight" android:duration="10" />   <item android:drawable="@drawable/nine" android:duration="10" />   <item android:drawable="@drawable/ten" android:duration="10" />   <item android:drawable="@drawable/eleven" android:duration="10" />   <item android:drawable="@drawable/twelve" android:duration="10" />   <item android:drawable="@drawable/thirteen" android:duration="10" />   <item android:drawable="@drawable/fourteen" android:duration="10" />   <item android:drawable="@drawable/fifteen" android:duration="10" />   <item android:drawable="@drawable/sixteen" android:duration="10" />   <item android:drawable="@drawable/seventeen" android:duration="10" />   <item android:drawable="@drawable/eighteen" android:duration="10" />   <item android:drawable="@drawable/nineteen" android:duration="10" />   <item android:drawable="@drawable/twenty" android:duration="10" />   <item android:drawable="@drawable/twentyone" android:duration="10" />    <item android:drawable="@drawable/twentytwo" android:duration="10" />   <item android:drawable="@drawable/twentythree" android:duration="10" />   <item android:drawable="@drawable/twentyfour" android:duration="10" />   <item android:drawable="@drawable/twentyfive" android:duration="10" />   <item android:drawable="@drawable/twentysix" android:duration="10" />   <item android:drawable="@drawable/twentyseven" android:duration="10" />   <item android:drawable="@drawable/twentyeight" android:duration="10" />   <item android:drawable="@drawable/twentynine" android:duration="10" />   <item android:drawable="@drawable/thirty" android:duration="10" />   <item android:drawable="@drawable/thirtyone" android:duration="10" />   <item android:drawable="@drawable/thirtytwo" android:duration="10" />   <item android:drawable="@drawable/thirtythree" android:duration="10" />   <item android:drawable="@drawable/thirtyfour" android:duration="10" />   <item android:drawable="@drawable/thirtyfive" android:duration="10" />   <item android:drawable="@drawable/thirtysix" android:duration="10" /> </animation-list>

主界面引用动画

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/layout"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical"     android:background="#fff">    <ImageView android:id="@+id/walk" android:layout_width="150dp"         android:layout_height="150dp"         android:background ="@anim/walk" /> </LinearLayout>

主界面代码

package WangLi.Graphics.Walk;import java.util.Timer;import java.util.TimerTask;import android.app.Activity;import android.graphics.drawable.AnimationDrawable;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.view.View;import android.view.View.OnClickListener;import android.view.animation.Animation;import android.view.animation.Animation.AnimationListener;import android.view.animation.TranslateAnimation;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.LinearLayout.LayoutParams;public class Walk extends Activity { //记录行走人ImageView当前的位置 private float curX = 0; private float curY = 30; //记录行走人ImageView下一个位置的坐标　 float nextX = 0; float nextY = 0;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        //获取显示行走人的ImageView组件        final ImageView imageView = (ImageView)findViewById(R.id.walk);        final Handler handler = new Handler()        {         public void handleMessage(Message msg)         {          if(msg.what == 0x123)          {           //横向上一直向右走           if(nextX > 320)           {            curX = nextX = 0;           }           else           {            nextX += 8;           }                      //纵向上随机上下走           nextY = curY + (float)(Math.random() * 10 - 5);           //设置显示行走人的ImageView位置发生位移改变           TranslateAnimation anim = new TranslateAnimation(curX,             nextX,              curY,              nextY);                      curX = nextX;           curY = nextY;           anim.setDuration(200);           anim.setFillEnabled(true);           //开始位移动画           imageView.startAnimation(anim);          }         }        };        final AnimationDrawable walk = (AnimationDrawable)imageView.getBackground();        imageView.setOnClickListener(new OnClickListener()        {         public void onClick(View v)         {          //开始播放人行走的逐帧动画          walk.start();          //通过定制器控制每0.2秒运行一次TanslateAnimation动画          new Timer().schedule(new TimerTask()          {           public void run()           {            handler.sendEmptyMessage(0x123);           }          }, 0, 200);         }        });    }}
