Android实现帧动画

1.在res的drawable下新建一个布局animation.xml*文件

"><animation-list xmlns:android="http://schemas.android.com/apk/res/android"    android:oneshot="true">    <item        android:drawable="@drawable/image1"        android:duration="32" />    <item        android:drawable="@drawable/image2"        android:duration="32" />    <item        android:drawable="@drawable/image3"        android:duration="32" />    <item        android:drawable="@drawable/image4"        android:duration="32" />    <item        android:drawable="@drawable/image5"        android:duration="32" />    <item        android:drawable="@drawable/image6"        android:duration="32" />    <item        android:drawable="@drawable/image7"        android:duration="32" />    <item        android:drawable="@drawable/image8"        android:duration="32" />    <item        android:drawable="@drawable/image9"        android:duration="32" />    <item        android:drawable="@drawable/image10"        android:duration="32" />    <item        android:drawable="@drawable/image11"        android:duration="32" />    <item        android:drawable="@drawable/image12"        android:duration="32" />    <item        android:drawable="@drawable/image13"        android:duration="32" />    <item        android:drawable="@drawable/image14"        android:duration="32" />    <item        android:drawable="@drawable/image15"        android:duration="32" />    <item        android:drawable="@drawable/image16"        android:duration="32" />    <item        android:drawable="@drawable/image17"        android:duration="32" />    <item        android:drawable="@drawable/image18"        android:duration="32" />    <item        android:drawable="@drawable/image19"        android:duration="32" />    <item        android:drawable="@drawable/image20"        android:duration="32" />    <item        android:drawable="@drawable/image21"        android:duration="32" />    <item        android:drawable="@drawable/image22"        android:duration="32" />    <item        android:drawable="@drawable/image23"        android:duration="32" />    <item        android:drawable="@drawable/image24"        android:duration="32" />    <item        android:drawable="@drawable/image25"        android:duration="32" />    <item        android:drawable="@drawable/image26"        android:duration="32" />    <item        android:drawable="@drawable/image27"        android:duration="32" />    <item        android:drawable="@drawable/image28"        android:duration="32" />    <item        android:drawable="@drawable/image29"        android:duration="32" />    <item        android:drawable="@drawable/image30"        android:duration="32" />    <item        android:drawable="@drawable/image31"        android:duration="32" />    <item        android:drawable="@drawable/image32"        android:duration="32" />    <item        android:drawable="@drawable/image33"        android:duration="32" />    <item        android:drawable="@drawable/image34"        android:duration="32" />    <item        android:drawable="@drawable/image35"        android:duration="32" />    <item        android:drawable="@drawable/image36"        android:duration="32" />    <item        android:drawable="@drawable/image37"        android:duration="32" />    <item        android:drawable="@drawable/image38"        android:duration="32" />    <item        android:drawable="@drawable/image39"        android:duration="32" />    <item        android:drawable="@drawable/image40"        android:duration="32" />    <item        android:drawable="@drawable/image41"        android:duration="32" />    <item        android:drawable="@drawable/image42"        android:duration="32" />    <item        android:drawable="@drawable/image43"        android:duration="32" />    <item        android:drawable="@drawable/image44"        android:duration="32" />    <item        android:drawable="@drawable/image45"        android:duration="32" />    <item        android:drawable="@drawable/image46"        android:duration="32" />    <item        android:drawable="@drawable/image47"        android:duration="32" />    <item        android:drawable="@drawable/image48"        android:duration="32" />    <item        android:drawable="@drawable/image49"        android:duration="32" />    <item        android:drawable="@drawable/image50"        android:duration="32" />    <item        android:drawable="@drawable/image51"        android:duration="32" />    <item        android:drawable="@drawable/image52"        android:duration="32" />    <item        android:drawable="@drawable/image53"        android:duration="32" />    <item        android:drawable="@drawable/image54"        android:duration="32" />    <item        android:drawable="@drawable/image55"        android:duration="32" />    <item        android:drawable="@drawable/image56"        android:duration="32" />    <item        android:drawable="@drawable/image57"        android:duration="32" />    <item        android:drawable="@drawable/image58"        android:duration="32" />    <item        android:drawable="@drawable/image59"        android:duration="32" />    <item        android:drawable="@drawable/image60"        android:duration="32" /></animation-list>

android:oneshot=”true”当为true时表示只播放一次，为false时表示循环播放；

2.给ImageView设置帧动画的src

    <ImageView        android:id="@+id/ivLoading"        android:layout_width="300dp"        android:layout_height="300dp"        android:layout_centerInParent="true"        android:src="@drawable/animation"        android:visibility="gone" />

3.播放帧动画

    ivLoading.setImageResource(R.drawable.animation);    drawable = (AnimationDrawable) ivLoading.getDrawable();    drawable.start();

4.以上播放默认是没有监听的，所以我们这里提供一种自定义View，可以监听帧动画播完的监听

/** * 自定义可以播放动态图片的ImageView */public class AnimationImageView extends ImageView {    public AnimationImageView(Context context) {        super(context);    }    public AnimationImageView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public AnimationImageView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    public interface OnFrameAnimationListener{        /**         * 动画开始播放后调用         */        void onStart();        /**         * 动画结束播放后调用         */        void onEnd();    }    /**     * 不带动画监听的播放     * @param resId     */    public void loadAnimation(int resId){        setImageResource(resId);        AnimationDrawable anim = (AnimationDrawable)getDrawable();        anim.start();    }    /**     * 带动画监听的播放     * @param resId     * @param listener     */    public void loadAnimation(int resId, final OnFrameAnimationListener listener) {        setImageResource(resId);        AnimationDrawable anim = (AnimationDrawable)getDrawable();        anim.start();        if(listener != null){            // 调用回调函数onStart            listener.onStart();        }        // 计算动态图片所花费的事件        int durationTime = 0;        for (int i = 0; i < anim.getNumberOfFrames(); i++) {            durationTime += anim.getDuration(i);        }        // 动画结束后        new Handler().postDelayed(new Runnable() {            @Override            public void run() {                if(listener != null){                    // 调用回调函数onEnd                    listener.onEnd();                }            }        }, durationTime);    }}

5.代码中加载并设置监听

            // 加载带监听的帧动画            anim_view.loadAnimation(R.drawable.anim_defense,                    new OnFrameAnimationListener() {                        @Override                        public void onStart() {                            // 动画刚播放时                        }                        @Override                        public void onEnd() {                            // 动画结束播放时                        }                    });
