android 2D动画实现

不管，先上截图

代码：只有一个activity

MainActivity：代码很简单

package com.animation.test;

import zhuojin.lession15.animation.frame.R;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class MainActivity extends Activity {

    ImageView img1=null;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        img1=(ImageView)findViewById(R.id.img1);
    }
    AnimationDrawable   anim=new AnimationDrawable();
    
    public  void startBtn(View v)
    {
      for(int i=0;i<8;i++)
      {
          anim.addFrame(this.getResources().getDrawable(R.drawable.walk1+i), 100);
      }
        anim.setOneShot(false);
        img1.setBackgroundDrawable(anim);
        if(anim.isRunning())
        {
            anim.stop();
        }else
        {
            anim.stop();
            anim.start();
        }
    }
}

代码结构

在drawbale文件夹下有个walkgirl.xml的文件，这个文件，实际上描述了切换图片的一个帧率。其实2D动画的实现也就是多个图片的展示

walkgirl.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="true" >
    <item android:drawable="@drawable/walk1" android:duration="50" />
    <item android:drawable="@drawable/walk2" android:duration="50" />
    <item android:drawable="@drawable/walk3" android:duration="50" />
    <item android:drawable="@drawable/walk4" android:duration="50" />
    <item android:drawable="@drawable/walk5" android:duration="50" />
    <item android:drawable="@drawable/walk6" android:duration="50" />
    <item android:drawable="@drawable/walk7" android:duration="50" />
    <item android:drawable="@drawable/walk8" android:duration="50" />
</animation-list>

无语了，这博客园怎么上传代码。。
