当返回到主显示片段时，GoogleMap片段会崩溃应用

标签： java android google-maps android-fragments

我有一个活动，在其xml中有一个framelayout，占用了大部分显示器，让不同的片段根据用户进出视图，如下所示：

dispatch_async(dispatch_get_main_queue(), ^{
/* Your UI code */
});

我有一个Track.java，假设设置并显示googlemaps，它确实如此，但是当我点击后退按钮然后尝试再次调用该片段时，应用程序崩溃了。

  

错误日志：

public void ShiftView(Object obj) {
        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.activity_main_framelayout, (Fragment) obj);
        ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        ft.addToBackStack(null);
        ft.commit();
    }

Track.java 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">

    <fragment
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/map"
        class="com.google.android.gms.maps.MapFragment" />


</RelativeLayout>

我怎样才能停止崩溃，所以它到目前为止的行为与其他每个片段一样？

Track.java中的

添加此代码以重绘地图

@Override
public void onDestroyView() {
    super.onDestroyView();
    MapFragment f = (MapFragment) getFragmentManager()
                                         .findFragmentById(R.id.map);
    if (f != null) 
        getFragmentManager().beginTransaction().remove(f).commit();
}
