如何setListner停止动画并向MainActivity Android发送回调

public interface AnimationListener {
    void onAnimationStopped();
}

public class MainActivity extends AppCompatActivity implements AnimationListener {
    // ...

    @Override
    public void onAnimationStopped() {
        // 处理动画停止后的逻辑
    }
}

public class AnimationClass {
    private AnimationListener listener;

    public void setAnimationListener(AnimationListener listener) {
        this.listener = listener;
    }
}

if (listener != null) {
    listener.onAnimationStopped();
}
