我想将文件发送到服务器,我需要从uri获得真正的路径.

我的代码:

public String getPathFromURI(Context context, Uri contentUri) {
    if ( contentUri.toString().indexOf("file:///") > -1 ){
        return contentUri.getPath();
    }

    Cursor cursor = null;
    try { 
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }finally {
          if (cursor != null) {
              cursor.close();
          }
    }
}

和onActivityResult:

...
imageName = data.getData();
imagePath = getPathFromURI(getBaseContext(),imageName);

Picasso.with(getBaseContext()).load(imageName).into(imageView);
...

如何在ImageView中显示图像,但imagePath总是为空？:) 谢谢
