Question

我试图运行它，但它一直给我错误。可能是进口问题吗？使用网格布局的XML给出了以下错误

<android.support.v7.widget.GridLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:alignmentMode="alignBounds"
    app:orientation="horizontal"
    android:padding="16dp"
    app:useDefaultMargins="true" 
    app:columnCount="1" >

<TextView 
        android:id="@+id/from_label"
        app:layout_gravity="fill_horizontal"
        android:text="@string/from"
        android:textColor="?android:textColorSecondary" />

    <AutoCompleteTextView
        android:id="@+id/from"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        app:layout_gravity="fill_horizontal"  
        android:completionThreshold="3" />  

    <TextView
        android:id="@+id/to_label"
        app:layout_gravity="fill_horizontal"
        android:text="@string/to"
        android:textColor="?android:textColorSecondary" />

    <AutoCompleteTextView
        android:id="@+id/to"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        app:layout_gravity="fill_horizontal"
        android:completionThreshold="3" />

    <Button
        android:id="@+id/load_directions"
        app:layout_columnSpan="@integer/create_account_pane_column_count"
        app:layout_gravity="fill_horizontal"
        android:text="@string/load_directions" />

</android.support.v7.widget.GridLayout>

错误：
一开始：

Multiple annotations found at this line:
    - error: No resource identifier found for 
     attribute 'columnCount' in package 
     'com.ecs.google.maps.v2.actionbarsherlock'
    - error: No resource identifier found for 
     attribute 'useDefaultMargins' in package 
     'com.ecs.google.maps.v2.actionbarsherlock'
    - error: No resource identifier found for 
     attribute 'alignmentMode' in package 
     'com.ecs.google.maps.v2.actionbarsherlock'
    - error: No resource identifier found for 
     attribute 'orientation' in package 
     'com.ecs.google.maps.v2.

再向下：

error: No resource identifier found for attribute 'layout_gravity' 
     in package 'com.ecs.google.maps.v2.actionbarsherlock'

这给了我一个读R的错误，我认为这是因为无论出于何种原因，它都没有与XML正确连接。

    </application>

</manifest>

我不认为这是多个错误，而是一个很大的错误，它会弄乱一切。
