Android逐帧动画的实现

一、代码实现：

private ImageView iv;private AnimationDrawable ad;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);iv = (ImageView) findViewById(R.id.iv);ad = new AnimationDrawable();ad.addFrame(getResources().getDrawable(R.drawable.pic1), 100);ad.addFrame(getResources().getDrawable(R.drawable.pic2), 100);ad.addFrame(getResources().getDrawable(R.drawable.pic3), 100);ad.addFrame(getResources().getDrawable(R.drawable.pic4), 100);ad.addFrame(getResources().getDrawable(R.drawable.pic5), 100);ad.setOneShot(false);//true则只运行一次，false可以循环iv.setBackgroundDrawable(ad);iv.setOnClickListener(new View.OnClickListener()//按钮点击的时候运行，再次点击停止{@Overridepublic void onClick(View v){if (ad.isRunning()){ad.stop();} else {ad.start();}}});}

第二种，配置文件的实现方式

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:drawable="@drawable/ic_launcher" android:duration="100"></item>    <item android:drawable="@drawable/newsdetails_titlebar_btn_next" android:duration="100"></item>    <item android:drawable="@drawable/newsdetails_titlebar_btn_next_selected" android:duration="100"></item>    <item android:drawable="@drawable/newsdetails_titlebar_btn_previous" android:duration="100"></item>    <item android:drawable="@drawable/newsdetails_titlebar_btn_previous_selected" android:duration="100"></item>    </animation-list>

代码调用部分：

private ImageView iv;private AnimationDrawable ad;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);iv = (ImageView) findViewById(R.id.iv);iv.setBackgroundResource(R.drawable.pic_anim);ad = (AnimationDrawable) iv.getBackground();iv.setOnClickListener(new View.OnClickListener(){@Overridepublic void onClick(View v){if (ad.isRunning()){ad.stop();} else {ad.start();}}});}
