问题描述

我正在使用Glide"将图像从服务器加载到 ImageView.我想知道是否可以从图像视图本身中提取该 URI.

I'm using 'Glide' to load image from a server to an ImageView. I would like to know if it's possible to extract that URI from the imageview itself.

ImageView contentImage = (ImageView) findViewById(R.id.contentImage);

........

Glide.with(getApplicationContext()).load(contentImageUrl)
.crossFade()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(contentImage);  

我的目标是在 Imageview 中分享图像.如何使用 Glide 获取 imageview 上的 URI?

My aim is to share the image in Imageview. How to get URI on imageview with Glide?

Uri uri = ??????????????

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Share Image"));

推荐答案

获取 Uri 将你的 Glide 实现更改为:

to get Uri change ur Glide implementation to:

Bitmap bitmap;

 Glide.with(getApplicationContext())
                .load(contentImageUrl)
                .asBitmap()
                .into(new SimpleTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                        // you can do something with loaded bitmap here
                        contentImage.setImageBitmap(resource);
                        bitmap= resource;
                    }
                });

现在调用方法；​​

    //get URI from bitmap
   Uri uri = getImageUri(getApplicationContext(),bitmap);

在getImageUri函数中:

public Uri getImageUri(Context inContext, Bitmap inImage) {
  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
  String path = MediaStore.Images.Media.insertImage(MainActivity.this.getContentResolver(), inImage, UUID.randomUUID().toString() + ".png", "drawing");
  return Uri.parse(path);
} 

您需要在清单中添加权限:

You need to add permission in manifest:

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

还有运行时权限:Api>=23

Also for runtime permission: Api>=23

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
