我正在使用 actionbarsherlock 及其 sherlockFragmentActivity。

我有 3 个片段和 Tab + ViewPager 布局。

第三个片段是问题所在。这是一个片段，在谷歌地图上显示我的位置。

据我所知，viewpager 将创建新页面，如果我们从一个页面滚动超过 1 页，那么它将破坏该页面。

所以第一次一切都很好，我转到第 2 页，它使用 GOOGLMAPS 在第 3 页调用 CREATE。

但是，问题是如果我回到第 1 页（DESTORIES 第 3 页 googlemaps）。现在，如果我回到第 2 页（尝试创建第 3 页），第 3 页的 inflater.inflate 会死掉，我会得到一个错误，首先是 Choreographer 类。

所以我的问题是，为什么 inflater.inflate 失败了，用这样的片段编程选项卡 viewpager 的正确方法是什么？？？？

此处的代码（在创建主要活动时）：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main_activity);
        mTabHost = (TabHost)findViewById(android.R.id.tabhost);
        mTabHost.setup();

        mViewPager = (ViewPager)findViewById(R.id.pager);

        mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager);

        mTabsAdapter.addTab(mTabHost.newTabSpec("driverInfo").setIndicator("Driver Info"),
                DriverInfo.class, null);
        mTabsAdapter.addTab(mTabHost.newTabSpec("alarmSystem").setIndicator("Alarm System"),
                AlarmSetting.class, null);
        mTabsAdapter.addTab(mTabHost.newTabSpec("vehicleLocation").setIndicator("Location"),
                VehicleLocation.class, null);


        if (savedInstanceState != null) {
            mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab"));
        }
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putString("tab", mTabHost.getCurrentTabTag());
    }

代码：位置片段：

public class VehicleLocation extends Fragment implements ServerRequestInterface {

    private GoogleMap mMap; 
    private ProgressDialog mProgressDialog;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        try
        {
            super.onCreate(savedInstanceState);
            setupProgressDialog();
        }
        catch (Exception ex)
        {
            System.out.println(ex.toString());
        }


}

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//WHere it keeps die-ing     ----------------------------------    
    View view = inflater.inflate(R.layout.vehicle_location, container, false);
            setUpMapIfNeeded();
            return view;
        }

在更多地盯着堆栈跟踪之后，我注意到了这条线

 Caused by: java.lang.IllegalArgumentException: Binary XML file line #2: Duplicate id 0x7f040066, tag null, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment

这导致我像谷歌一样，这解决了我的问题：

ID、标签 null 或父 ID 与 com.google.android.gms.maps.MapFragment 的另一个片段重复
