DrawerLayout中的LinearLayout中的ListView崩溃

Question

当我将LinearLayout作为DrawerLayout ListView父DrawerLayout时，出现此错误：

Caused by: java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.support.v4.widget.DrawerLayout$LayoutParams

例如：

<!-- Framelayout to display Fragments -->

<FrameLayout
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<!-- Listview to display slider menu -->

<LinearLayout
    android:id="@+id/DrawerLinear"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />
</LinearLayout>

Answer 1

为LinearLayout设置layout_gravity

    <!-- Framelayout to display Fragments -->

<FrameLayout
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<!-- Listview to display slider menu -->

    <LinearLayout
    android:id="@+id/DrawerLinear"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="start"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />
</LinearLayout>

您必须将它们分组在抽屉布局中，并将重力属性设置为线性布局，以将其视为抽屉内容：

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Framelayout to display Fragments -->

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->

    <LinearLayout
        android:id="@+id/DrawerLinear"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" 
        android:layout_gravity="start">

        <ListView
            android:id="@+id/list_slidermenu"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:background="@color/list_background"
            android:choiceMode="singleChoice"
            android:divider="@color/list_divider"
            android:dividerHeight="1dp"
            android:listSelector="@drawable/list_selector" />
    </LinearLayout>

</android.support.v4.widget.DrawerLayout>
