android.view.InflateException扩展类片段时出错
我试图从5天后解决这个问题，但我仍然没有解决它。
主要Java代码
package com.beproject.ourway; import android.app.Fragment; import android.app.FragmentManager; import android.os.Bundle; import android.os.Handler; import android.support.v4.app.FragmentActivity; import android.support.v4.widget.DrawerLayout; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.ListView; import android.widget.Toast; public class MainHome extends FragmentActivity{ private String[] mNavigationDrawerItemTitles; private DrawerLayout mDrawerLayout; private ListView mDrawerList; Fragment fragment = null; FragmentManager fragmentManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_home); // Initialization mNavigationDrawerItemTitles= getResources().getStringArray(R.array.navigation_drawer_items_array); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.left_drawer); // Defining drawer items ObjectDrawerItem[] drawerItem = new ObjectDrawerItem[6]; drawerItem[0] = new ObjectDrawerItem(R.drawable.ic_launcher, "Home"); drawerItem[1] = new ObjectDrawerItem(R.drawable.ic_launcher, "Places"); drawerItem[2] = new ObjectDrawerItem(R.drawable.ic_launcher, "Friends"); drawerItem[3] = new ObjectDrawerItem(R.drawable.ic_launcher, "Settings"); drawerItem[4] = new ObjectDrawerItem(R.drawable.ic_launcher, "Help"); drawerItem[5] = new ObjectDrawerItem(R.drawable.ic_launcher, "About"); DrawerItemCustomAdapter adapter = new DrawerItemCustomAdapter(this, R.layout.home_drawer_item, drawerItem); mDrawerList.setAdapter(adapter); mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); // selectItem(0); } public class DrawerItemClickListener implements ListView.OnItemClickListener { @Override public void onItemClick(AdapterView parent, View view, int position, long id) { selectItem(position); } } void selectItem(int position) { switch (position) { case 0: { fragment = new HomeFragment(); break; } case 1: fragment = new PlacesFragment(); break; default: break; } if (fragment != null) { fragmentManager = getFragmentManager(); fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit(); mDrawerList.setItemChecked(position, true); mDrawerList.setSelection(position); getActionBar().setTitle(mNavigationDrawerItemTitles[position]); mDrawerLayout.closeDrawer(mDrawerList); } else { Log.e("MainActivity", "Error in creating fragment"); } } public static class HomeFragment extends Fragment { public HomeFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_home, container, false); return rootView; } } public static class PlacesFragment extends Fragment { public PlacesFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_places, container, false); return rootView; } } } 主XML文件
fragment_home.xml
fragment_places.xml
logcat的

当我从导航抽屉中单击主菜单项时，它工作正常。 但是当我再次点击Home之后，我得到了这个例外
02-16 20:08:05.714: E/AndroidRuntime(5999): android.view.InflateException: Binary XML file line #8: Error inflating class fragment
在java代码中有任何更正吗？ 请帮我解决这个问题。
谢谢
将以下变量添加到Fragment类：
private static View view;
然后在同一个片段类中尝试替换onCreateView方法：
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if(view != null) { ViewGroup parent = (ViewGroup) view.getParent(); if(parent != null) { parent.removeView(view); } } try { view = inflater.inflate(R.layout.fragment_places, container, false); } catch(InflateException e){ // map is already there, just return view as it is } return view;
}
