Question

我创建了ToolBar和GridView。工具栏上的GridView 。

我希望GridView位于工具栏下方。以下是我的xml代码，这是错误的......

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/widget"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:layout_scrollFlags="scroll|enterAlways"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
        </android.support.design.widget.AppBarLayout>
    </android.support.design.widget.CoordinatorLayout>
    <GridView
        android:id="@+id/gridView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:columnWidth="100dp"
        android:drawSelectorOnTop="true"
        android:gravity="center"
        android:numColumns="2"
        android:stretchMode="columnWidth"
        android:verticalSpacing="5dp"
        android:focusable="true"
        android:layout_below="@+id/widget"
        android:clickable="true"/>
</RelativeLayout>

你需要在CoordinatorLayout中添加网格视图，如下所示：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/widget"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
    </android.support.design.widget.AppBarLayout>
<GridView
    android:id="@+id/gridView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
    android:columnWidth="100dp"
    android:drawSelectorOnTop="true"
    android:gravity="center"
    android:numColumns="2"
    android:stretchMode="columnWidth"
    android:verticalSpacing="5dp"
    android:focusable="true"
    android:layout_below="@+id/widget"
    android:clickable="true"/>
</android.support.design.widget.CoordinatorLayout>
