Store中可繪製的圖像到你的內部存儲，並選擇圖片。這種方式可以幫助你。

try{ 

     Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.shareforma); 
     String extStorageDirectory = Environment.getExternalStorageDirectory().toString(); 
     File file = new File(extStorageDirectory, "forma.PNG"); 
     FileOutputStream outStream = new FileOutputStream(file); 
     bm.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
     outStream.flush(); 
     outStream.close(); 
    } 
    catch (IOException e) { 
     e.printStackTrace(); 
    } 
    String msgText = "Sample Message"; 

    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); 
    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
    shareIntent.setType("image/*"); 

    //set your message 
    shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, msgText); 

    String imagePath = Environment.getExternalStorageDirectory() + File.separator + "image_name.jpg"; 

    File imageFileToShare = new File(imagePath); 

    Uri uri = Uri.fromFile(imageFileToShare); 

    shareIntent.putExtra(Intent.EXTRA_STREAM, uri); 

    startActivity(Intent.createChooser(shareIntent, msgText));
