Firebase Android試圖推動孩子，然後一個孩子以下

令人困惑的標題，我知道，但不是很舒服如何解釋。這裏會盡我所能。Firebase Android試圖推動孩子，然後一個孩子以下

我試圖完成的是，當用戶點擊一個按鈕時，來自一個字段的文本被推送到firebase，然後下一個字段的文本被推到下面。

事情是這樣的：

- 「UID」 - 「Scripttitle」 - 「在scriptUrl」

這裏，我想用這樣做代碼：

final EditText title = (EditText) rlLayout.findViewById(R.id.inputScriptTitle); 
     final EditText scripturl = (EditText) rlLayout.findViewById(R.id.inputScriptURL); 
     final Button button = (Button) rlLayout.findViewById(R.id.submitScriptButton); 
     button.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
         .push() 
         .child("scripttitle") 
         .setValue(title.getText().toString()); 

        new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
          .push() 
          .child(title.getText().toString()) 
          .setValue(scripturl);

我很確定我只是在做一些非常基本的錯誤，但由於我是編程新手，我無法真正瞭解可能的原因。

該錯誤的logcat是：

替換您如下代碼

new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
          .push() 
          .child(title.getText().toString()) 
          .setValue(scripturl);

與

new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
          .push() 
          .child(title.getText().toString()) 
          .setValue(scripturl.getText().toString());

//因爲你直接傳遞對象值法取代並傳遞來自編輯的文本數據並不反對

謝謝。那裏錯誤的錯誤。我知道這一點，但由於某種原因無法看到它。修正了這個錯誤，但是我沒有給出我所需要的Firebase數據結構，因此必須進一步做實驗。謝謝你的幫助。 –

歡迎 - 符文Langaard –

你不能設置視圖給setValue。 scripturl是一個EditText。

new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
         .push() 
         .child(title.getText().toString()) 
         .setValue(scripturl);

如果您使用那樣的話您沒有看到任何錯誤。

new Firebase("https://theatre-assistant.firebaseio.com/scripts") 
      .child(title.getText().toString()) 
      .push() 
      .setValue(scripturl.getText().toString);
