如何加载与毕加索位图而不使用ImageView的？ [英] How to load a Bitmap with Picasso without using an ImageView?

问题描述

使用的ImageView ，我可以使用下面的code下载图像回调

With ImageView, I can use the following code to download image with callback

Picasso.with(activity).load(url).into(imageView, new Callback()
{
    @Override
    public void onSuccess() 
    {
        // do something
    }

    @Override
    public void onError() { }
);

或者简单地从这个 Picasso.with（活动）.load位图（URL）获得（）; 。反正是有增加的回调只是下载的图片？如果可能的话，请提供样品code，干杯！

Or simply get the Bitmap from this Picasso.with(activity).load(url).get();. Is there anyway to add callback for just download the image? If possible please provide sample code, Cheers!

推荐答案

您可以创建 目标，然后办理位图里面的目标回调方法。

You can create a Target and then handle the Bitmap inside the Targets callback methods.

这是如何：

// make sure to set Target as strong reference
private Target loadtarget;

public void loadBitmap(String url) {

    if (loadtarget == null) loadtarget = new Target() {
        @Override
        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
            // do something with the Bitmap
            handleLoadedBitmap(bitmap);
        }

        @Override
        public void onBitmapFailed() {

        }
    };

    Picasso.with(this).load(url).into(loadtarget);
}

public void handleLoadedBitmap(Bitmap b) {
    // do something here
}
