实现

在deawable 新建文件 frame_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@mipmap/d_0"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_1"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_2"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_3"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_4"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_5"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_6"
        android:duration="100" />
    <item
        android:drawable="@mipmap/d_7"
        android:duration="100" />
</animation-list>

使用

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_frame_anim);
        mImageView = (ImageView) findViewById(R.id.iv);
        mImageView.setImageResource(R.drawable.frame_anim);
        AnimationDrawable animationDrawable = (AnimationDrawable) mImageView.getDrawable();
        animationDrawable.setOneShot(false);  //循环
        animationDrawable.start();
    }

Java 代码实现

 private void initAnimationDrawable() {
        AnimationDrawable mAnimationDrawable = new AnimationDrawable();
        for (int i = 0; i < 8; i++) {
            int id = getResources().getIdentifier("d_" + i, "mipmap", getPackageName());
            Drawable drawable = getResources().getDrawable(id);
            mAnimationDrawable.addFrame(drawable, 100);
        }
        mImageView.setImageDrawable(mAnimationDrawable);
        mAnimationDrawable.setOneShot(false);
        mAnimationDrawable.start();
    }
