【AndroidStudio问题记录】libheif三方库解析hdr图片，切换过程有卡顿_基于libheif

解决：使用多线程延迟加载avif图片，推荐使用HandlerThread来开启线程

代码参考如下：

    private HandlerThread mImageLoadThread;
 
    private Handler mImageLoadHandler;
 
    private void init(){
        mImageLoadThread = new HandlerThread(TAG + "-ImageLoadThread");
        mImageLoadThread.start();
        mImageLoadHandler = new ImageLoadHandler(mImageLoadThread.getLooper());
        mImageLoadHandler.sendEmptyMessage(MSG_LOAD_HDR_IMAGE);
    }
 
	private void loadBitmap() {...}
 
	private class ImageLoadHandler extends Handler {
        ImageLoadHandler(Looper looper) {
            super(looper);
        }
 
        @Override
        public void handleMessage(Message msg) {
            Log.i(TAG, "handleMessage msg.what = " + msg.what);
            if (msg.what == MSG_LOAD_HDR_IMAGE) {
                loadBitmap();
            }
        }
    }
