只有第一個值在android網格視圖正在返回

Question

我有一個網格視圖充滿edittexts。當用戶按下按鈕時，我想要檢索存儲在edittext中的所有值，但我只是返回第一個值。

網格視圖位於fragment_score.xml中。

網格視圖grid_items.xml

<EditText 
    android:id="@+id/grid_item_edit_text_red" 
    android:inputType="number" 
    android:layout_width="50dp" 
    android:layout_height="50dp" 


    /> 

<EditText 
    android:id="@+id/grid_item_edit_text_blue" 
    android:inputType="number" 
    android:layout_width="50dp" 
    android:layout_height="50dp" 

    />

我用在編輯文本的文本觀察家和更新從那裏

Answer 2

編輯的文本，我還是有點一款Android新手，但我認爲你應該爲每個EditText都有一個id，而你只有定義2.
所以當你做(EditText)mView.findViewById(R.id.grid_item_edit_text_red)它會每次都返回相同的EditText。
這可能有點幫助：http://developer.android.com/guide/topics/ui/layout/gridview.html

Answer 3

有一個在getview方法的問題... 爲u已經使用的佈局充氣膨脹的EDITTEXT得到串 但你要知道，這是EDITTEXT包含數據

轉至for循環語句以獲取所有字符串。

運行for循環 鑑於使用EDITTEXT的數目.. for循環

（如果edittext.gettext（）長度（）> 0。） 字符串數據= edittext.gettext（）;
