share image with URL android share intent
提问by Amanni
I need to know if it is possible to share an image using only its url with a share intent. Here is my code.
我需要知道是否可以仅使用具有共享意图的 url 来共享图像。这是我的代码。
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.
到目前为止它不起作用，我还没有在网上找到任何有用的答案。我想使用共享意图而不下载图像来执行此操作。

You can share image using share intent, but you've to decode image to a localized Bitmap
您可以使用共享意图共享图像，但您必须将图像解码为本地化位图
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..."));
loadedImageis the loaded bitmap from http://eofdreams.com/data_images/dreams/face/face-03.jpg
loadedImage是从http://eofdreams.com/data_images/dreams/face/face-03.jpg加载的位图

See here HERE
在这里看到
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 :
然后将此添加到您的活动中：
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;
}

将 url 转换为字符串格式
Intent imageIntent = new Intent(Intent.ACTION_SEND);
Uri imageUri = Uri.parse("http://eofdreams.com/data_images/dreams/face/face-03.jpg");
