一个头像加载的类，用于异步获取资源，自定义View定义后加载

代码如下




public class HeadPositionView {

    private static final String TAG = "HeadPositionView";

    private View view;
    //头像地址
    private String ulr;

    private Context context;

    private AvatarLoadCompleteCallback avatarLoadCompleteCallback;

    public HeadPositionView(String ulr, Context context, AvatarLoadCompleteCallback avatarLoadCompleteCallback) {
        this.ulr = ulr;
        this.context = context;
        this.avatarLoadCompleteCallback = avatarLoadCompleteCallback;
        initView();
    }

    private void initView() {
        if (view == null) {
            view = View.inflate(context, R.layout.view_baidu_location, null);
        }
        LogUtil.d(TAG, "head url " + ulr);
        CircleImageView headView = view.findViewById(R.id.iv_head_baidu);
        RequestOptions options = new RequestOptions()
                .error(R.drawable.default_custom_default);
        Glide.with(context)
                .load(ulr)
                .apply(options)
                .into(new SimpleTarget<Drawable>() {
                    @Override
                    public void onResourceReady(Drawable resource, Transition<? super Drawable> transition) {
                        headView.setImageDrawable(resource);
                        avatarLoadCompleteCallback.getView(view);
                    }
                });
    }

    //Glide加载头像是异步调用，完成加载后，再生成bitMap在百度地图上绘制
    public interface AvatarLoadCompleteCallback{
        void getView(View view);
    }

}
