如何以编程方式通过 whatsapp android 共享图像和文本

你可以这样试一试

  public static void shareOnWhatsapp(Context context, String str) {
    Uri parse = Uri.parse(str);
    Intent intent = new Intent();
    intent.setAction("android.intent.action.SEND");
    intent.setPackage("com.whatsapp");
    String stringBuilder = context.getResources().getString(R.string.play_more_app) +
            context.getPackageName();
    intent.putExtra("android.intent.extra.TEXT", stringBuilder);
    intent.putExtra("android.intent.extra.STREAM", parse);
    intent.setType("image/*");
    intent.addFlags(1);
    try {
        context.startActivity(intent);
    } catch (Exception unused) {
        setToast(context, context.getResources().getString(R.string.whatsapp_not_installed));
    }
}

我用这个功能分享了它工作的图像，我希望它也能为你工作.

Edit个

1. 添加此依赖项以将URL转换为位图

       implementation 'com.github.bumptech.glide:glide:4.14.2'
   

2. 使用此函数获取要共享的图像URI

       private Uri getImageURI(Bitmap image) {
       File imagesFolder = new File(getCacheDir(), "images");
       Uri uri = null;
       try {
           imagesFolder.mkdirs();
           File file = new File(imagesFolder, "shared_image.png");
   
           FileOutputStream stream = new FileOutputStream(file);
           image.compress(Bitmap.CompressFormat.PNG, 90, stream);
           stream.flush();
           stream.close();
           uri = FileProvider.getUriForFile(this, getPackageName() + ".provider", file);
   
       } catch (IOException e) {
           Log.d("TAG", "IOException while trying to write file for sharing: " + e.getMessage());
       }
       return uri;
   }
   

3. 使用此功能在WhatsApp上共享图像

       public static void shareOnWhatsapp(Context context, Uri uri) {
       Intent intent = new Intent();
       intent.setAction("android.intent.action.SEND");
       intent.setPackage("com.whatsapp");
       String stringBuilder = "Your String Or Message" +
               context.getPackageName();
       intent.putExtra("android.intent.extra.TEXT", stringBuilder);
       intent.putExtra("android.intent.extra.STREAM", uri);
       intent.setType("image/*");
       intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
       try {
           context.startActivity(intent);
       } catch (Exception unused) {
           Toast.makeText(context, "whatsapp not installed", Toast.LENGTH_SHORT).show();
       }
   }
   

4. 像这样使用

           findViewById(R.id.btnShare).setOnClickListener(v -> {
           Glide.with(this).asBitmap().load( /*Your URL*/ "https://drinkprime.in/images/smart_water_purifier.jpg").into(new CustomTarget<Bitmap>() {
               @Override
               public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                   Bitmap bitmap = resource;
                   shareOnWhatsapp(MainActivity.this, getImageURI(bitmap));
               }
   
               @Override
               public void onLoadCleared(@Nullable Drawable placeholder) {
               }
           });
       });
   

它现在完全起作用了
