Android - Picasso 未将 URL 图像加载到

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天气图标中iconUrl = "http://openweathermap.org/img/w/"+icon+".png";Picasso.get().load(iconUrl).into(Tab1Fragment.weatherIcon);这是我正在尝试加载的图像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。图像未加载，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 2

对于 picasso，您必须导入 lib，如果没有 picasso，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);

希望它会有所帮助
