Android-Picasso无法将URL图像加载到片段ImageView中

Question

我的毕加索版本是：implementation 'com.squareup.picasso:picasso:2.71828'

我正在尝试将以下图像加载到我的ImageView weatherIcon

iconUrl = "http://openweathermap.org/img/w/"+icon+".png";
Picasso.get().load(iconUrl).into(Tab1Fragment.weatherIcon);

这是我要加载的图像

上面图片的URL

http://openweathermap.org/img/w/04n.png

我的Tab1Fragment代码

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.tab1_fragment, container, false);

    weatherIcon = (ImageView) rootView.findViewById(R.id.imageView);

    return rootView;

}

但是，没有运气。图像不会加载，而且有趣的是，毕加索语句停止了所有后续语句，例如TextViews中的SetText等。

Answer 1

使用

    iconUrl ="http://openweathermap.org/img/w/04n.png"
    Picasso.with(context).load(iconUrl).placeholder(R.drawable.user_image)// Place 
        holder image from drawable folder
       .error(R.drawable.user_image).resize(110, 110).centerCrop()
       .into(weatherIcon);

Answer 2

对于毕加索，您必须导入lib，而无需毕加索，您可以直接使用url填充imageview

URL url = new URL("give_url_here");
Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
imageView.setImageBitmap(bmp);

希望这会有所帮助
