如何从SD卡中使用毕加索库中加载图像 [英] How to load image from SD card using Picasso library
问题描述
我需要加载从SD卡的图像到GridView中。 为了提高效率,我使用的毕加索库
Picasso.with(活动).load(images.get(位置).getDataPath())
.resize(96,96).centerCrop()成(viewHolder.image)。
我用下面的code的适配器。不幸的是中号无法看到任何图片 所以请任何一个可以帮助。
注意 而且还任何人都可以提出任何有效的图像加载库从SD卡装载图像。
要求 我不滚动时每次加载图像。如果已经装上滚动不要加载图像
要加载你需要将其转换为一个URI第一文件
开放的URI = Uri.fromFile(新文件(images.get(位置).getDataPath()));
Picasso.with(活性).load(URI)
.resize(96,96).centerCrop()成(viewHolder.image)。
要求我不滚动时每次加载图像。如果它 已经装上滚动不要加载图像
- 在毕加索是非常适合这种

To load the file you need to convert it to a uri first
Uri uri = Uri.fromFile(new File(images.get(position).getDataPath()));
Picasso.with(activity).load(uri)
.resize(96, 96).centerCrop().into(viewHolder.image);

- Picasso is excellent for this
