Question

我有一个填充了edittexts的网格视图。当用户按下按钮时，我想要检索存储在edittexts中的所有值，但我只回到第一个。

网格视图位于fragment_score.xml中。

网格视图中的编辑文本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"

     />

Answer 1

我仍然是一个Android新手，但我认为你应该为每个EditText都有一个id，你只定义了2.
因此，当您执行(EditText)mView.findViewById(R.id.grid_item_edit_text_red)时，它每次都会返回相同的EditText 这可能有点帮助：http://developer.android.com/guide/topics/ui/layout/gridview.html

Answer 2

getview方法存在问题...... 因为你使用布局充气器来扩充editText来获取字符串但是你需要知道哪个editText包含数据

转到for循环语句以获取所有字符串。

运行for循环作为视图中使用的editText的数量。 for loop

（如果是edittext.gettext（）。length（）＆gt; 0） String data = edittext.gettext（）;

Answer 3

我通过在编辑文本上使用文本观察器并从那里更新数组来修复它

只返回android网格视图中的第一个值
