Question

我需要知道是否可以仅使用具有共享意图的网址来共享图像。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);

到目前为止，它无法正常工作，我在网上找不到任何有用的答案。我想使用共享意图并且不下载图像来执行此操作。

您可以使用共享意图共享图片，但您已将图片解码为本地化的位图

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..."));

loadedImage是来自http://eofdreams.com/data_images/dreams/face/face-03.jpg

的加载位图

请参阅此处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
                }

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;
}

Answer 3

将网址转换为字符串格式

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

Answer 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"));
