我有导航条（菜单滑块），可以为您提供google api中的位置。
当您选择抽屉列表的某个位置时，应替换新地图。 地图是在xml上定义的。
问题在于，当它第二次被替换时，它会将片段空白....第三次它被很好地替换（？）。我需要的是，如果每次我选择一个新的地方，地图都会成功替换方法，而不是第三次。
当第二次更换时，它会进入膨胀异常....检查许多答案告诉我为视图验证添加的方法应该有效......但它没有。还有关于destroyView的方法..就像那个方法不能很好地删除片段一样..
这是我的地图片段地点：

以下是我在主要活动中替换它的方法：
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Currently selected item in spinner first is airport!!!
mTitle = setPlaceTag.getTag() ;
setPlaceTag.setPosition(position - 1);
// Creating a fragment object
mapfragmentplaces rFragment = new mapfragmentplaces();
// Getting reference to the FragmentManager
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
// Creating a fragment transaction
android.support.v4.app.FragmentTransaction ft = fragmentManager.beginTransaction();
// Adding a fragment to the fragment transaction
ft.replace(R.id.content_frame, rFragment);
// Committing the transaction
ft.commit();
// Closing the drawer
mDrawerLayout.closeDrawer(mDrawerList);
}
}

我已经在这个问题上做了答案：
Error inflating class fragment - duplicate id/illegalargumentexception?
但没有人工作......任何人都可以帮忙吗？ ......谢谢。
