如何在 Android 中将图像 URL 共享到 WhatsApp？

Question

我需要在我的应用程序中将图像分享给 WhatsApp。我有图片网址。为了分享到 WhatsApp，我使用以下代码。

String image_url = "http://images.cartradeexchange.com//img//800//vehicle//Honda_Brio_562672_5995_6_1438153637072.jpg";

URI uri = null;
try {
    uri = new URI(image_url.toString());
} catch (URISyntaxException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Log.e("uri=", "" + uri);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/jpg");

// Target whatsapp:
shareIntent.setPackage("com.whatsapp");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

try {
    startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(InventoryManageOnlineActivity.this,
            "Whatsapp have not been installed.",
            Toast.LENGTH_SHORT).show();
}

但它没有用。我收到以下错误。

为此，我在 Google 上进行了很多搜索，并按照以下 URL 进行操作

Android sharing image doesn't work.

但这对我没有用。请教我如何分享图片网址。

Answer 1

尝试改变这一行

sharingIntent.putExtra(android.content.Intent.EXTRA_STREAM, url);

这个

sharingIntent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.fromFile(image_url )); 
// Use direct image url instead of uri

让我知道它是否适合您。

查看这个答案

How to share an image on whats app which is set on an ImageView in android.

顺便说一句，我不明白你为什么要这样做image_url.toString()？它已经在字符串中了吗？

也试试这段代码。

String image_url = "http://images.cartradeexchange.com//img//800//vehicle//Honda_Brio_562672_5995_6_1438153637072.jpg";

        Intent shareIntent = new Intent();
        shareIntent.setType("image/*");
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        shareIntent.setAction(Intent.ACTION_SEND);
        //without the below line intent will show error
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT, image_url);
                // Target whatsapp:
        shareIntent.setPackage("com.whatsapp");
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

                try {
                    startActivity(shareIntent);
                } catch (android.content.ActivityNotFoundException ex) {
                    Toast.makeText(InventoryManageOnlineActivity.this,
                            "Whatsapp have not been installed.",
                            Toast.LENGTH_SHORT).show();
                }

Answer 3

通过使用它，您可以在 whatsapp 上发送文字和网址。

sendIntent.setPackage("com.whatsapp");

仅在 whatsapp 上使用分享消息，您可以在其中选择要分享的联系人。

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "http://images.cartradeexchange.com//img//800//vehicle//Honda_Brio_562672_5995_6_1438153637072.jpg");
 sendIntent.setType("text/plain");
 sendIntent.setPackage("com.whatsapp");
 startActivity(sendIntent);

在清单中添加互联网权限

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

使用下面的代码：-

   whatsapp.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent intent1 = c.getPackageManager().getLaunchIntentForPackage("com.whatsapp");
                    if(intent1!=null)
                    {
                        Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
                        whatsappIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        whatsappIntent.setType("image/*");
                        whatsappIntent.setPackage("com.whatsapp");
                        String url = Spacecraft.new_image_array.get(position);
                        new Download_GIF(url).execute();
                        Uri imageUri = Uri.parse("file:///storage/emulated/0/downloadedFile.gif");
                        whatsappIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
                        c.startActivity(whatsappIntent);
                    }

下载_GIF类。

public class Download_GIF extends AsyncTask<String, Void, String> {
    static String url_image=null;

    public Download_GIF(String url) {
        this.url_image = url;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(String... params) {

        String filepath = null;
        try {
            //set the download URL, a url that points to a file on the internet
            //this is the file to be downloaded
            URL url = new URL(url_image);
            //create the new connection
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            //set up some things on the connection
            urlConnection.setRequestMethod("GET");
            urlConnection.setDoOutput(true);
            //and connect!
            urlConnection.connect();
            //set the path where we want to save the file
            //in this case, going to save it on the root directory of the
            //sd card.
            File SDCardRoot = Environment.getExternalStorageDirectory();
            //create a new file, specifying the path, and the filename
            //which we want to save the file as.

            String filename = "downloadedFile.gif";   // you can download to any type of file ex:.jpeg (image) ,.txt(text file),.mp3 (audio file)
            Log.i("Local filename:", "" + filename);
            File file;
            file = new File(SDCardRoot, filename);
            if (file.createNewFile()) {
                file.createNewFile();
            }

            //this will be used to write the downloaded data into the file we created
            FileOutputStream fileOutput = new FileOutputStream(file);

            //this will be used in reading the data from the internet
            InputStream inputStream = urlConnection.getInputStream();

            //this is the total size of the file
            int totalSize = urlConnection.getContentLength();
            //variable to store total downloaded bytes
            int downloadedSize = 0;

            //create a buffer...
            byte[] buffer = new byte[1024];
            int bufferLength = 0; //used to store a temporary size of the buffer

            //now, read through the input buffer and write the contents to the file
            while ((bufferLength = inputStream.read(buffer)) > 0) {
                //add the data in the buffer to the file in the file output stream (the file on the sd card
                fileOutput.write(buffer, 0, bufferLength);
                //add up the size so we know how much is downloaded
                downloadedSize += bufferLength;
                //this is where you would do something to report the prgress, like this maybe
                Log.i("Progress:", "downloadedSize:" + downloadedSize + "totalSize:" + totalSize);

            }
            //close the output stream when done
            fileOutput.close();
            if (downloadedSize == totalSize) filepath = file.getPath();

            //catch some possible errors...
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            filepath = null;
            e.printStackTrace();
        }
        Log.i("filepath:", " " + filepath);

        return filepath;


    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
    }
}

首先您需要在 glide 中加载图片，然后您可以将其分享到任何地方。

从 glide 加载图像的代码（图像正在保存到存储中，您可以稍后将其删除）

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);
                    Log.i("quoteswahttodo", "is onresoursereddy" + path);
                    Uri screenshotUri = Uri.parse(path);
                    Log.i("quoteswahttodo", "is onresoursereddy" + screenshotUri);
                    intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
                    intent.setType("image/*");
                    startActivity(Intent.createChooser(intent, "Share image via..."));  // if you want to share with whatsapp only replace with below code 
                }
                @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);
               }
});

这里替换为 Whatsapp：

 sendd.setPackage("com.whatsapp");
 try {
         startActivity(sendd);
 } catch (Exception e) {
         Toast.makeText(FinishedDoing.this, "It seem like Whatsapp is not been installed", Toast.LENGTH_SHORT).show();
                e.printStackTrace();
 }
