android–MapFragment在旋转后变得无法响应

概述我的问题很简单,我将4个FrameLayout添加到我的XML中,并在这些容器中按代码添加4个MapFragment.像这样：<LinearLayoutxmlns:android="http://schemas.android.com/apkes/android"xmlns:map="http://schemas.android.com/apkes-auto"android:id="@+id/map_container&

我的问题很简单,我将4个FrameLayout添加到我的XML中,并在这些容器中按代码添加4个MapFragment.

像这样 ：

<linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"  xmlns:map="http://schemas.androID.com/apk/res-auto"  androID:ID="@+ID/map_container"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent"  androID:orIEntation="vertical">  <linearLayout    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:layout_weight="0.5"    androID:orIEntation="horizontal">    <FrameLayout      androID:ID="@+ID/map1_container"      androID:layout_wIDth="match_parent"      androID:layout_height="match_parent"      androID:layout_weight="0.5""/>    <FrameLayout      androID:ID="@+ID/map2_container"      androID:layout_wIDth="match_parent"      androID:layout_height="match_parent"      androID:layout_weight="0.5"/>  </linearLayout>  <linearLayout    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:layout_weight="0.5"    androID:orIEntation="horizontal">    <fragment      androID:ID="@+ID/map3_container"      androID:layout_wIDth="match_parent"      androID:layout_height="match_parent"      androID:layout_weight="0.5"/>    <fragment      androID:ID="@+ID/map4_container"      androID:layout_wIDth="match_parent"      androID:layout_height="match_parent"      androID:layout_weight="0.5""/>  </linearLayout>

问题是：当我旋转设备时,MapFragments不再重新触摸事件……

有没有人有同样的问题并解决它？

解决方法:

我遇到了同样的问题,经过多次故障排除后发现容器中有多个地图碎片.

所以,我通过使用解决了这个问题

FragmentTransaction.replace

代替

.add
