Question

我想弄清楚这里是不对的，我正在为用户构建一个表单，以便能够上传个人资料图片。当点击按钮它会带你到Android画廊（想让用户在那里拍照）但是一旦选择了一张图片，应用程序崩溃不确定为什么，但我认为错误是指向与getRealPathFromURI（currImageURI）下面的方法我试过寻找不同的解决方案，但它们似乎对如何做到这一点有相同的反应......就像这样How to get the Full file path from URI http://monstercoda.wordpress.com/2012/04/15/android-image-upload-tutorial-part-i/

代码：

@Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            if(resultCode == RESULT_OK) {
                if(requestCode == 1) {
                              Uri currImageURI = data.getData();
                    Log.d("The path","Current image path is ---->" + getRealPathFromURI(currImageURI));
                    TextView tv_path = (TextView) findViewById(R.id.path);
                    tv_path.setText(getRealPathFromURI(currImageURI));

                }
            }
        }

        public String getRealPathFromURI(Uri contentUri) {
            String res = null;
            String[] proj={MediaStore.Images.Media.DATA};
            Cursor cursor = getContentResolver().query(contentUri,proj, null, null, null);
            if(cursor.moveToFirst()) {
                int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                res = cursor.getString(column_index);
            }
            cursor.close();
            return res;
        }

错误：

Answer 1

是，问题在getRealPathFromURI inside the onActivityResult，

错误是，

Caused by: java.lang.IllegalArgumentException: Unknown column requested: _data
com.fslio.wardrobe.getRealPathFromURI(wardrobe.java:80)
com.fslio.wardrobe.onActivityResult(wardrobe.java:67)

调试代码，在选择图像时，数据会出现问题。
