我在我的Android应用中使用NavigationDrawer，我已经制作了自己的自定义布局XML文件及其适配器但是当我运行我的程序时，我的应用程序崩溃了以下日志，我无法追踪原因那么，有什么建议吗？
activity_main.xml中
<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
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="@+id/list_slider_menu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:choiceMode="singleChoice" />
</android.support.v4.widget.DrawerLayout>

答案 0 :(得分：16)
您的ListView必须在xml中指定android:layout_gravity属性，以便DrawerLayout将其标识为滑动抽屉。
使用right，left，start，end作为值。
答案 1 :(得分：4)
我遇到了与Android Hive教程相同的问题。但在我找到一个神奇的解决方案之后。
将android:layout_gravity="start"或android:layout_gravity="left"放入ListView
<ListView
android:id="@+id/listSlideMenu"
android:layout_width="240dp"
android:layout_height="fill_parent"
android:layout_gravity="left"
android:choiceMode="singleChoice"
android:dividerHeight="1dp"
android:background="@color/color_primary"/>
我得到了同样的问题从androidhive学习完全使用gravity =“start”，但是在重力变化时结束它会引发错误
答案 2 :(得分：0)
使用
DrawerLayout时确保它是 rootLayout 。不要让它成为LinearLayout或RelativeLayout的孩子。
as closeDrawer提出两个覆盖函数第一个View和第二个Gravity
通常情况下它靠近重力。所以为了关闭抽屉，你必须设置
android:layout_gravity =""
并且所有android：layout_gravity在DrawerLayout中都必须是唯一的
drawer.closeDrawer(GravityCompat.START)//this code close the drawer child with layout_gravity ="start".
如果您有其他视图，例如 linearLayout上面的listView ，请将layout_gravity提供给layout并将其从listView中删除。抽屉在重力的基础上关闭项目
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
///drawer.closeDrawer(anyViewToClose);
drawer.closeDrawer(GravityCompat.START);//but it is better to do this using gravity.
请参阅closeDrawer代码
public void closeDrawer(@EdgeGravity int gravity, boolean animate) {
final View drawerView = findDrawerWithGravity(gravity);
if (drawerView == null) {
throw new IllegalArgumentException("No drawer view found with gravity "
+ gravityToString(gravity));
}
closeDrawer(drawerView, animate);
}
另见isDrawerView
boolean isDrawerView(View child) {
final int gravity = ((LayoutParams) child.getLayoutParams()).gravity;
final int absGravity = GravityCompat.getAbsoluteGravity(gravity,
ViewCompat.getLayoutDirection(child));
if ((absGravity & Gravity.LEFT) != 0) {
// This child is a left-edge drawer
return true;
}
if ((absGravity & Gravity.RIGHT) != 0) {
// This child is a right-edge drawer
return true;
}
return false;
}
