1.animation-list

帧布局文件（顺序显示动画和倒序显示动画）(其中oneshot代表着是否只展示一遍，false会不停的循环播发动画)

在drawable中创建animation_list.xml文件

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="true">    <item android:drawable="@mipmap/ic_launcher1" android:duration="150"/>    <item android:drawable="@mipmap/ic_launcher2" android:duration="150"/>    <item android:drawable="@mipmap/ic_launcher3" android:duration="150"/>    <item android:drawable="@mipmap/ic_launcher4" android:duration="150"/>    <item android:drawable="@mipmap/ic_launcher5" android:duration="150"/></animation-list>

布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"    android:layout_height="match_parent"

    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    android:orientation="vertical"    >    <ImageView        android:id="@+id/imageView"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/animation_list"/>    <Button        android:id="@+id/btn_start"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="开始动画"/>    <Button        android:id="@+id/btn_end"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="停止动画"/></LinearLayout>

Activity:

public class Secondctivity extends AppCompatActivity implements View.OnClickListener {    private ImageView imageView;    private Button btn_stsart,btn_end;    private AnimationDrawable animationDrawable;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_secondctivity);        imageView = (ImageView) findViewById(R.id.imageView);        btn_stsart = (Button) findViewById(R.id.btn_start);        btn_end = (Button) findViewById(R.id.btn_end);        btn_stsart.setOnClickListener(this);        btn_end.setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.btn_start://开始动画                imageView.setImageResource(R.drawable.animation_list);                animationDrawable = (AnimationDrawable) imageView.getDrawable();                animationDrawable.start();                break;            case R.id.btn_end://结束动画                animationDrawable = (AnimationDrawable) imageView.getDrawable();                animationDrawable.stop();                break;        }    }}
