如何在android中获取捕获图像的路径

Question

我正在开发一个Android应用程序.它具有捕获图像应显示在屏幕上的功能,我需要获取该图像路径,以便我可以将该图像发送到服务器.

我能够在屏幕上显示图像,但无法获得绝对图像路径.

我正在走路:

content://media/external/images/media/1220
content://media/external/images/media/1221

我怎样才能获得实际的图像路径？

这是我的代码:

mintent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
mintent.putExtra(MediaStore.EXTRA_OUTPUT,
                 MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
startActivityForResult(mintent, 1);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  if ((data != null && !data.toString().equalsIgnoreCase("Intent {  }"))
      || requestCode == 1)
    switch (requestCode) {
      case 1:
        try {
          // Uri imageFileUri = data.getData();
          // String path=getRealPathFromURI(this,imageFileUri);
          // Bitmap bitmap = (Bitmap) data.getExtras().get("data");

          String photoPath = null;
          Bitmap bitmap = (Bitmap) data.getExtras().get("data");
          Intent intent = new Intent(this, Media.class);
          intent.putExtra("BitmapImage", bitmap);

          Bundle b = mintent.getExtras();
          if (b != null && b.containsKey(MediaStore.EXTRA_OUTPUT)) { // large
            // image?
            String timeStamp = new SimpleDateFormat(
                "yyyyMMdd_HHmmss").format(new Date());
            // Shouldn't have to do this ... but
            photoPath = MediaStore.Images.Media.insertImage(
                        getContentResolver(), bitmap, "Img" + timeStamp
                        + ".jpeg", null);
          }
        }
    }
}

photoPath 值如上所示.

如何从此路径获取绝对图像路径.

这是一个有效的功能 -

String selectedImagePath = getPath(selectedImageUri);

private String getPath(Uri uri) {

    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(uri, projection, null, null,null);

    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();

    return cursor.getString(column_index);
}
