Question

基本上我要做的是允许用户拍照，然后在他们保存图片后，他们可以打开图库（在应用程序内）并查看图片。但是图片没有显示在画廊中。这是我迄今为止所拥有的。这是拍摄和保存照片时目录的样子：

/storage/sdcard0/Android/data/'my app'/files/ArcFlash/study1/Transformer/trans1/trans1_time_date.png

在图片意图之后，我有onActivityResult（我压缩图片）：

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == 1)
    {
        if(resultCode == RESULT_OK)
        {
            SharedPreferences sharedPrefs = getSharedPreferences("userPrefs", Context.MODE_PRIVATE);
            String path = sharedPrefs.getString("path", null);

            filesToScan.add(path);//ex: /storage/sdcard0/Android/data/'my app'/files/.... 

            Bitmap capturedImage;

            if(path != null)
            {
                capturedImage = BitmapFactory.decodeFile(path);

                //Bitmap bitmap = Bitmap.createScaledBitmap(capturedImage, 60, 60, true);
                File newPic = new File(path);

                FileOutputStream fos = null;
                try {
                    fos = new FileOutputStream(newPic);
                    capturedImage.compress(Bitmap.CompressFormat.JPEG, 70, fos);
                    fos.flush();
                    fos.close();

                    String test = "file://"+ context.getExternalFilesDir(null).toString() + "/ArcFlash/";

                    for(int i = 0; i < filesToScan.size(); ++i)
                    {
                        File pic = new File(filesToScan.get(i));
                        Uri uri = Uri.fromFile(pic);
                        sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, uri));
                    }
                }
                catch(Exception ex)
                {
                    handler.Log(ex.getMessage(), "onActivityResult()", context);
                    Log.i("customException", "error compressing image: " + ex.getMessage());
                }
            }
        }
    }
}

我的filesToScan是ArrayList<String>

sendBroadCast（Intent.ACTION_MEDIA_MOUNTED）不起作用
