如何使用Android中的ActionBarSherlock在Fragment中保存视图状态

Question

我正在使用ActionBarSherlock创建一个包含三个片段的滑动标签活动。每个片段都有一个自定义视图或在运行时添加的多个自定义视图，我希望能够保存片段的状态。我有进度条，我使用的只是米，当我旋转设备时，它们会回到0，当我转到最后的片段时，它会做同样的事情。我已经用不同的方式寻找了一段时间，包括setRetainInstance（true）和android：configChanges，但到目前为止还没有一个有效。请任何人帮助我。

以下是片段1的代码：

public class Fragment_1 extends SherlockFragment
{
private View view;
private PVLayout pvLayout; // Process value container view configuration class instance
private SlidingTabsActivity slidingTabsActivity;
private DeviceInfo deviceInfo;
private Page page;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    view = inflater.inflate(R.layout.fragment_pv, container, false);

    return view;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) 
{
    super.onActivityCreated(savedInstanceState); 
    setRetainInstance(true);

    /* Creates the new views from the configuration class */
    slidingTabsActivity = (SlidingTabsActivity) getSherlockActivity();
    deviceInfo = slidingTabsActivity.getDeviceInfo();
    page = slidingTabsActivity.getPage1(); 

    pvLayout = new PVLayout(slidingTabsActivity);
    pvLayout.setDeviceInfo(deviceInfo);
    pvLayout.setPage(page);
    pvLayout.createView();
}   
}

片段2：

public class Fragment_2 extends SherlockFragment 
{
private View view;
private ConfigLayout configLayout;
private SlidingTabsActivity slidingTabsActivity;
private DeviceInfo deviceInfo;
private Page page;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    view = inflater.inflate(R.layout.fragment_config, container, false);

    return view;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) 
{
    super.onActivityCreated(savedInstanceState); 
    setRetainInstance(true);

    /* Creates the new view from the configuration class */
    slidingTabsActivity = (SlidingTabsActivity) getSherlockActivity();
    deviceInfo = slidingTabsActivity.getDeviceInfo();
    page = slidingTabsActivity.getPage2();

    configLayout = new ConfigLayout(slidingTabsActivity);
    configLayout.setDeviceInfo(deviceInfo);
    configLayout.setPage(page);
    configLayout.createView();
}
}

片段3：

public class Fragment_3 extends SherlockFragment 
{
private View view;
private DiagLayout diagLayout;
private SlidingTabsActivity slidingTabsActivity;
private DeviceInfo deviceInfo;
private Page page;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    view = inflater.inflate(R.layout.fragment_diag, container, false);

    return view;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) 
{
    super.onActivityCreated(savedInstanceState); 
    setRetainInstance(true);

    /* Creates the new view from the configuration class */
    slidingTabsActivity = (SlidingTabsActivity) getSherlockActivity();
    deviceInfo = slidingTabsActivity.getDeviceInfo();
    page = slidingTabsActivity.getPage3();

    diagLayout = new DiagLayout(slidingTabsActivity);
    diagLayout.setDeviceInfo(deviceInfo);
    diagLayout.setPage(page);
    diagLayout.createView(); 
}   
}
