前面讲了三大动画的视图动画，现在就来简单介绍一下帧动画。

现在先来看一下效果：

一.使用xml布局的形式

1.在drawable目录下新建一个xml

<?xml version="1.0" encoding="utf-8"?><animation-list xmlns:android="http://schemas.android.com/apk/res/android">    <item        android:drawable="@drawable/icon1"        android:duration="300"></item>    <item        android:drawable="@drawable/icon2"        android:duration="300"></item>    <item        android:drawable="@drawable/icon3"        android:duration="300"></item>    <item        android:drawable="@drawable/icon4"        android:duration="300"></item>    <item        android:drawable="@drawable/icon5"        android:duration="300"></item>    <item        android:drawable="@drawable/icon6"        android:duration="300"></item></animation-list>

2.布局xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <ImageView        android:id="@+id/main3_image"        android:src="@drawable/icon1"        android:layout_gravity="center"        android:layout_width="wrap_content"        android:layout_height="wrap_content" /></LinearLayout>

3.Java代码

public class Main3Activity extends AppCompatActivity{    private ImageView image;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main3);        initView();    }    private void initView() {        image= (ImageView) findViewById(R.id.main3_image);        image.setImageResource(R.drawable.my_frame_animation);        AnimationDrawable animationDrawable= (AnimationDrawable) image.getDrawable();        animationDrawable.start();    }}

二.使用代码的形式

public class Main3Activity extends AppCompatActivity{    private ImageView image;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main3);        initView();    }    private void initView() {        AnimationDrawable animationDrawable=new AnimationDrawable();        Drawable drawable=getResources().getDrawable(R.drawable.icon1);        Drawable drawable2=getResources().getDrawable(R.drawable.icon2);        Drawable drawable3=getResources().getDrawable(R.drawable.icon3);        Drawable drawable4=getResources().getDrawable(R.drawable.icon4);        Drawable drawable5=getResources().getDrawable(R.drawable.icon5);        Drawable drawable6=getResources().getDrawable(R.drawable.icon6);        //添加图片        animationDrawable.addFrame(drawable,300);        animationDrawable.addFrame(drawable2,300);        animationDrawable.addFrame(drawable3,300);        animationDrawable.addFrame(drawable4,300);        animationDrawable.addFrame(drawable5,300);        animationDrawable.addFrame(drawable6,300);        animationDrawable.setOneShot(false);        image.setImageDrawable(animationDrawable);        animationDrawable.start();    }}
