如何从库图像选择器中检索图像 android

Question

请问如何从这个库中检索图像？

https://github.com/akshay2211/PixImagePicker

我不知道如何从该库中检索图像。我想在我的主 activity 上展示。我一直在尝试从指南中添加此代码

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == Activity.RESULT_OK && requestCode == RequestCode) {
                ArrayList<String> returnValue = data.getStringArrayListExtra(Pix.IMAGE_RESULTS);
        }
    }

这是我使用 glide

检索图像的源代码

 for (int i = 0; i < returnValue.size(); i++) {
            String path = returnValue.get(i);
            StringBuilder builder = new StringBuilder(path);
            builder.deleteCharAt(0);
            File file = new File(builder.toString());
            Uri imageUri = Uri.fromFile(file);

            Glide.with(this)
                    .load(imageUri)
                    .onlyRetrieveFromCache(true)
                    .into(imageView);

            System.out.println("value : " + returnValue.get(i));
            //LoadImageFromWebOperations(returnValue.get(i));
        }

而且我总是会遇到这样的错误

W/Glide: Load failed for file:///storage/emulated/0/DCIM/Camera/IMG_20191116_110843.jpg with size [1080x1542]
    class com.bumptech.glide.load.engine.GlideException: Failed to load resource

Answer 1

从源代码来看，它包含一个图像网址列表：资料来源：https://github.com/akshay2211/PixImagePicker/blob/master/pix/src/main/java/com/fxn/pix/Pix.java

ArrayList<String> list = new ArrayList<>(); 
for (Img i : selectionList) 
{ list.add(i.getUrl()); // Log.e("Pix images", "img " + i.getUrl());
 } 
Intent resultIntent = new Intent(); resultIntent.putStringArrayListExtra(IMAGE_RESULTS, list);

所以您需要遍历 url 列表并加载相应的图像。

以下是一种这样的方法：

public static Drawable LoadImageFromWebOperations(String url) {
    try {
        InputStream is = (InputStream) new URL(url).getContent();
        Drawable d = Drawable.createFromStream(is, "src name");
        return d;
    } catch (Exception e) {
        return null;
    }

}

Answer 2

   for (int i = 0; i < returnValue.size(); i++) {
        String path = returnValue.get(i);

        System.out.println ( "path: " + path);

        Glide.with(this)
                .load(path)
                .onlyRetrieveFromCache(true)
                .into(imageView);

        break; // load only one image in the imageview
     }

请说出path的值。

   .onlyRetrieveFromCache(true)

不知道对不对

在你需要的清单中

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

并且您应该添加代码以在运行时要求用户确认该权限。

returnValue.size() 的值是多少？
