android 逐帧动画

android 逐帧动画 研究了一下下，超简单。一步步按照我流程来弄！

创建一个android项目test.

一：在res创建一个anim文件夹，该文件夹下创建firefox_animation.xml文件

代码如下

<?xml version="1.0" encoding="utf-8"?>  

<animation-list       
    xmlns:android="http://schemas.android.com/apk/res/android"     
    android:oneshot="false">
 
		
		<item android:duration="300" android:drawable="@drawable/sound_2" /> 
		<item android:duration="300" android:drawable="@drawable/sound_3" /> 
		<item android:duration="300" android:drawable="@drawable/sound_4" /> 
		<item android:duration="300" android:drawable="@drawable/sound_5" /> 
		<item android:duration="300" android:drawable="@drawable/sound_6" /> 
		<item android:duration="300" android:drawable="@drawable/sound_7" /> 
		<item android:duration="300" android:drawable="@drawable/sound_8" /> 
		<item android:duration="300" android:drawable="@drawable/sound_9" /> 
		<item android:duration="300" android:drawable="@drawable/sound_10" /> 
		<item android:duration="300" android:drawable="@drawable/sound_11" /> 
		<item android:duration="300" android:drawable="@drawable/sound_12" /> 
		<item android:duration="300" android:drawable="@drawable/sound_13" /> 
		<item android:duration="300" android:drawable="@drawable/sound_14" /> 
		<item android:duration="300" android:drawable="@drawable/sound_15" /> 
		<item android:duration="300" android:drawable="@drawable/sound_16" /> 
		<item android:duration="300" android:drawable="@drawable/sound_17" /> 
		<item android:duration="300" android:drawable="@drawable/sound_18" /> 
		<item android:duration="300" android:drawable="@drawable/sound_19" /> 
		<item android:duration="300" android:drawable="@drawable/sound_20" /> 
		<item android:duration="300" android:drawable="@drawable/sound_21" /> 
		<item android:duration="300" android:drawable="@drawable/sound_22" /> 
		<item android:duration="300" android:drawable="@drawable/sound_23" /> 
		<item android:duration="300" android:drawable="@drawable/sound_24" /> 
		<item android:duration="300" android:drawable="@drawable/sound_25" />
		<item android:duration="300" android:drawable="@drawable/sound_26" />
		<item android:duration="300" android:drawable="@drawable/sound_27" />
		<item android:duration="300" android:drawable="@drawable/sound_28" />
		<item android:duration="300" android:drawable="@drawable/sound_29" />
		<item android:duration="300" android:drawable="@drawable/sound_30" />
		<item android:duration="300" android:drawable="@drawable/sound_31" />
		<item android:duration="300" android:drawable="@drawable/sound_32" />  
		              
</animation-list>

 二：在main.xml代码如下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="wrap_content" android:layout_height="wrap_content"
	android:orientation="vertical">



	<ImageView android:id="@+id/imageview1" android:layout_width="100px"
		android:layout_height="100px" android:src="@anim/firefox_animation">
	</ImageView>

	<Button android:id="@+id/start" android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:text="Start">
	</Button>

	<Button android:id="@+id/start_once" android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:text="Start_once">
	</Button>
</LinearLayout>

 三：在MianActivity中代码

package com.test;

import android.app.Activity;
import android.os.Bundle;

import android.graphics.drawable.AnimationDrawable;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class MainA extends Activity {
    private AnimationDrawable draw = null;
    private Button start = null;
    private Button startOnce = null;
    private boolean isoneshot = true;
    
    public void onCreate(Bundle bundle)
    {
     super.onCreate(bundle);
     this.setContentView(R.layout.main);
     ImageView view = (ImageView)findViewById(R.id.imageview1);
     draw = (AnimationDrawable)view.getDrawable();
     start = (Button)findViewById(R.id.start);
     start.setOnClickListener(new OnClickListener()
     {
      public void onClick(View v) {
       // TODO Auto-generated method stub
       startAnimation();
      }
     });
     startOnce = (Button)findViewById(R.id.start_once);
     startOnce.setOnClickListener(new OnClickListener()
     {

      public void onClick(View v) {
       // TODO Auto-generated method stub
       if(isoneshot)
       {
        startOnce.setText("startOnce");
       }
       else
       {
        startOnce.setText("Play Repace");
       }
       draw.setOneShot(isoneshot);
       isoneshot = !isoneshot;
      }
      
     });
    }
    
    private void startAnimation()
    {
     if(draw.isRunning())
     {
      draw.stop();
     }
     else
     {
      draw.stop();
      draw.start();
     }
    }
   }

 

完成！
