如何从链接共享图像,即不用下载图像,只需使用按钮共享即可

首先您需要在glide中加载图像(因为您正在使用glide),然后您可以将其共享到任何地方,但图像将保存到存储中

从glide加载图像的代码(图像正在保存到存储器中,您可以稍后删除它)

       Glide.with(getApplicationContext())
                    .load(imagelink)   \\link of your image file (url)
                    .asBitmap().skipMemoryCache(true).diskCacheStrategy(DiskCacheStrategy.NONE)

                    .into(new SimpleTarget<Bitmap>(250, 250) {
                        @Override
                        public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {


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


                            Uri screenshotUri = Uri.parse(path);



                            intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
                            intent.setType("image/*");

                            startActivity(Intent.createChooser(intent, "Share image via..."));
                        }

                        @Override
                        public void onLoadFailed(Exception e, Drawable errorDrawable) {
                            Toast.makeText(getApplicationContext(), "Something went wrong", Toast.LENGTH_SHORT).show();


                            super.onLoadFailed(e, errorDrawable);
                        }

                        @Override
                        public void onLoadStarted(Drawable placeholder) {
                            Toast.makeText(getApplicationContext(), "Starting", Toast.LENGTH_SHORT).show();

                            super.onLoadStarted(placeholder);
                        }
});

实际上链接也是一个文本,所以你可以这样分享它:

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, yourUrlOfImage);
sendIntent.setType("text/plain");
startActivity(sendIntent);
