Question

目前正在试用Google的Places API，同时尝试将Place推送到我的Firebase数据库。下面的代码尝试这样做，但在调用它时会出错。

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            Place place = PlacePicker.getPlace(this, data);
            String toastMsg = String.format("Place: %s", place.getName());
            Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();

            String userUid = FirebaseAuth.getInstance().getCurrentUser().getUid();
            DatabaseReference userRef = database.getReference("users/" + userUid);

            userRef.setValue(place);
        }
    }
}

我得到的错误如下：

对代码格式感到抱歉。我无法让它工作。

课程var dataTask: URLSessionDataTask? let url = NSURL(string: "https://itunes.apple.com/search?media=music&entity=song&term=test") dataTask = defaultSession.dataTask(with: url! as URL) { data, response, error in if let error = error { print(error.localizedDescription) } else if let _ = response as? HTTPURLResponse { print("ok") } } dataTask?.resume()并不意味着直接保存到Firebase中。

您应该编写一个简单的POJO类，其中只包含Place中需要的字段，复制数据，并将此简单对象保存到数据库中。

Firebase数据库冲突的getter用于name：getAddress
