Question

我正在尝试从SD卡中拍摄照片，以防万一用户从谷歌照片中选择，但从图库或文件管理器等任何其他应用中选择时会出现curserindexoutofbound错误。这是一段代码。

OnActivity结果 ` { if（requestCode == PICK_IMAGE_REQUEST＆amp;＆amp; resultCode == Activity.RESULT_OK＆amp;＆amp; data！= null＆amp;＆amp; data.getData（）！= null） { Uri uri = null; String realPath = null;

        try
        {
            uri = data.getData();
            Log.e("uri",uri.toString());
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);

            imageView.setImageBitmap(bitmap);

            String imagePath = getRealPathFromURI(uri);

            File source = new File(imagePath);

            String destinationPath = Environment.getExternalStorageDirectory().toString() + "/IASFolders/"+Configuration.empcode+".jpg";



            File destination = new File(destinationPath);
            try
            {
                InputStream in = new FileInputStream(source.getAbsolutePath());
                OutputStream out = new FileOutputStream(destination.getAbsolutePath());

                byte[] buf = new byte[1024];
                int len;
                while ((len = in.read(buf)) > 0)
                {
                    out.write(buf, 0, len);
                }

                in.close();
                out.close();

            }
            catch (IOException e)
            {
                e.printStackTrace();
                Log.d("File Copy Exception", e.toString());
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

}

`{getRealPathFromURI function

private String getRealPathFromURI(Uri contentURI) {
    String result;
    Cursor cursor = getActivity().getContentResolver()
            .query(contentURI,new String[]{MediaStore.Images.Media.DATA},MediaStore.Images.Media.DISPLAY_NAME+"=?" ,new String[]{Configuration.empcode},null);

    /*
    * Cursor imageCursor=getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,new String[]{MediaStore.Images.Media.DATA},MediaStore.Images.Media.DISPLAY_NAME+"=?" ,new String[]{imageTitle},null);
                    imageCursor.moveToFirst();
                    String imageData=imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
                    Long imageSize=imageCursor.getLong(imageCursor.getColumnIndex(ImageColumns.SIZE));
                    Toast.makeText(getApplicationContext(), String.valueOf(imageSize), Toast.LENGTH_LONG).show();*/
    if (cursor == null)
    {
        result = contentURI.getPath();
    }
    else
    {
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
        result = cursor.getString(idx);
        cursor.close();
    }
    return result;
}

试试这个

   if (Build.VERSION.SDK_INT <= 19) {
