HiFrameAnimation
低内存消耗的序列帧库,只占用了一张序列帧图片的内存,异步绘制不占用UI线程资源,同时复用序列帧Bitmap,减少内存抖动,避免了频繁的GC,提高动画的流畅性。可用于直播大礼物的展示。
使用了inBitmap复用内存
为了节省内存,我在每一帧绘制前才从本地读取并且编码图片,绘制完成后就释放,但这样的话会频繁地进行IO操作,造成内存抖动。为了减少内存抖动,我使用了inBitmap来复用当前帧所占用内存,效果还是很不错,内存抖动明显减缓了。
怎么使用
1.添加帧动画视图布局
<org.limlee.hiframeanimationlib.FrameAnimationView
android:id="@+id/frame_animation"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
2.添加序列帧资源
List<FrameDrawable> frameDrawables = new ArrayList<>();
for (String framePath : frameList) {
FrameDrawable frameDrawable = new FrameDrawable(FRAME_NAME + "/" + framePath, 100);
frameDrawables.add(frameDrawable);
}
mFrameAnimationView.addFrameDrawable(frameDrawables);
3.播放帧动画
@Override
protected void onPostCreate(@Nullable Bundle savedInstanceState) {
....
mFrameAnimationView.setOneShot(false); //循环播放帧动画
mFrameAnimationView.setOnFrameListener(new FrameAnimationView.OnFrameListener() { //添加监听器
@Override
public void onFrameStart() {
Log.d(TAG, "帧动画播放开始!");
}
@Override
public void onFrameEnd() {
Log.d(TAG, "帧动画播放结束!");
}
});
mFrameAnimationView.start(); //开始播放
}
4.停止播放
@Override
protected void onDestroy() {
super.onDestroy();
mFrameAnimationView.stop(); //停止播放
mFrameAnimationView.setOnFrameListener(null); //移除监听器
}
最后,还可以使用属性动画来实现负责的大礼物动画
