Wie kann ich Gif-Bilder mit anderen Apps teilen?

Question

Ich verwende Glide, um GIF-Bilder in einen RecyclerView zu laden.

Glide.with(context).load(imageUrl.trim()) 
       .asGif() 
       .placeholder(R.drawable.coming) 
       .error(R.drawable.error) 
       .diskCacheStrategy(DiskCacheStrategy.SOURCE) 
       .into(holder.gif_image); 

Answer 1

, wenn Ihr GIF-Bild auf Web

whatsapp.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Intent whatsappIntent = new Intent(Intent.ACTION_SEND); 
        whatsappIntent.setFlags(FLAG_ACTIVITY_NEW_TASK); 
        whatsappIntent.setType("image/*"); 
        whatsappIntent.setPackage("com.whatsapp"); 
        new Download_GIF(image).execute(); 
        Uri imageUri = Uri.parse("file:///storage/emulated/0/downloadedFile.gif"); 
        whatsappIntent.putExtra(Intent.EXTRA_STREAM, imageUri); 
        try { 
         startActivity(whatsappIntent); 
        } catch (android.content.ActivityNotFoundException ex) { 
         try { 
          Intent intent = new Intent(Intent.ACTION_VIEW); 
          intent.setData(Uri.parse("market://details?id=com.whatsapp")); 
          startActivity(intent); 
         } catch (Exception e) { 
          Intent intent = new Intent(Intent.ACTION_VIEW); 
          intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.whatsapp")); 
          intent.setFlags(FLAG_ACTIVITY_NEW_TASK); 
          startActivity(intent); 
         } 
        } 
       } 
      }); 

hier whatsapp Image ist

       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();

     return filepath; 


    } 

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

Sie können keine Gifs zwischen Android Apps teilen, weil es kein Protokoll dafür gibt. sorry Freund.

vielleicht, wenn Sie zwischen Apps teilen möchten für Sie gebaut, können Sie das Bild und ein Flag (Header oder einen anderen Parameter) zu serialisieren, um zu wissen, dass es ein gif ist.
