android - 如何从android中的画廊获取地址

Question

我编写这段代码，我的代码从图库中选择一张图片并从中获取数据，但我不知道如何从 Inputstrem 或数据中获取图像地址并存储它？

public void loadPic()
{
    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, 1);
}

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode==1)
    {
        try {
            Uri selectedImage=data.getData();
            InputStream inputStream = getContentResolver().openInputStream(selectedImage);
            listItems.add(inputStream.toString());
        } catch (FileNotFoundException e) {

            e.printStackTrace();
        }
    }
}

读取如下文件名，相应地使用它。

            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            File f = new File(picturePath);
            String imageName = f.getName();
