android 2D動畫實現

不管，先上

代碼：只有一個activity

MainActivity：代碼很簡單

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();        }    }}

代碼結構

在drawbale檔案夾下有個walkgirl.xml的檔案，這個檔案，實際上描述了切換圖片的一個幀率。其實2D動畫的實現也就是多個圖片的展示

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>

無語了，這部落格園怎麼上傳代碼。。
