share image with URL android share intent

问题:

I need to know if it is possible to share an image using only its url with a share intent. Here is my code.

Intent imageIntent = new Intent(Intent.ACTION_SEND);
Uri imageUri = Uri.parse("http://eofdreams.com/data_images/dreams/face/face-03.jpg");
imageIntent.setType("image/*");
imageIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(imageIntent);

So far its not working and I haven't found any helpful answers online. I would like to do this using the share intent and without downloading the image.

You can share image using share intent, but you've to decode image to a localized Bitmap

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
String path = Images.Media.insertImage(getContentResolver(), loadedImage, "", null);
Uri screenshotUri = Uri.parse(path);

intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));

loadedImage is the loaded bitmap from http://eofdreams.com/data_images/dreams/face/face-03.jpg

See here HERE

final ImageView imgview= (ImageView)findViewById(R.id.feedImage1);

                Uri bmpUri = getLocalBitmapUri(imgview);
                if (bmpUri != null) {
                    // Construct a ShareIntent with link to image
                    Intent shareIntent = new Intent();
                    shareIntent.setAction(Intent.ACTION_SEND);
                    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
                    shareIntent.setType("image/*");
                    // Launch sharing dialog for image
                    startActivity(Intent.createChooser(shareIntent, "Share Image"));    
                } else {
                    // ...sharing failed, handle error
                }

then add this to your activity :

public Uri getLocalBitmapUri(ImageView imageView) {
    // Extract Bitmap from ImageView drawable
    Drawable drawable = imageView.getDrawable();
    Bitmap bmp = null;
    if (drawable instanceof BitmapDrawable){
       bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    } else {
       return null;
    }
    // Store image to default external storage directory
    Uri bmpUri = null;
    try {
        File file =  new File(Environment.getExternalStoragePublicDirectory(  
            Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
        file.getParentFile().mkdirs();
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();
        bmpUri = Uri.fromFile(file);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}

convert url to string format

Intent imageIntent = new Intent(Intent.ACTION_SEND);
Uri imageUri = Uri.parse("http://eofdreams.com/data_images/dreams/face/face-03.jpg");
imageIntent.setType("image/*");
imageIntent.putExtra(Intent.EXTRA_STREAM, String.valueOf(imageUri));
startActivity(imageIntent);

回答4:

Intent intent = new Intent(Intent.ACTION_SEND);

intent.setType("text/plain");

intent.putExtra(Intent.EXTRA_TEXT,"http://eofdreams.com/data_images/dreams/face/face-03.jpg"); 

startActivity(Intent.createChooser(intent, "Share Image"));
