我有一个Live Android应用程序,从市场我收到了以下堆栈跟踪,我不知道为什么它发生在应用程序代码中没有发生,但它是由应用程序中的一些或其他事件引起的(假设)

我没有使用Fragments,仍然有FragmentManager的引用.如果任何机构可以对某些隐藏的事实进行一些说明以避免此类问题:

我正在尝试创建一个我正在构建的应用程序从主要活动中获取搜索词,返回结果,然后使结果可以被点击,以便可以从每个结果中查看详细信息.我这样做是通过使用MainActivity,ResultsActivity和PlaceActivity,然后是ListFragmentClickable(扩展ListFragment).如果手机朝向纵向模式,则结果列表应该是可见的,只有在单击结果时才会查看详细信息.如果手机是横向的,则在选择项目时,应在列表右侧弹出详细信息窗口.

在运行时,我收到一个错误,上面写着"错误膨胀类片段".我不知道是什么导致它,我很乐意帮助摆脱它.

我的ListFragmentClickables由我的ResultsActivity调用,它位于:

public class ResultsActivity extends FragmentActivity implements ListFragmentClickable.OnItemSelectedListener{

private ArrayAdapter<String> mAdapter;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_results_view);

    //Receive searchTerm from MainActivity
    Intent intent = getIntent();
    String searchTerm = intent.getStringExtra(MainActivity.SEARCH_TERM);

    mAdapter = new ArrayAdapter<String>(this, R.layout.item_label_list);

    FragmentManager     fm = getSupportFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();

    FactualResponderFragment responder = (FactualResponderFragment) fm.findFragmentByTag("RESTResponder");
    if (responder == null) {
        responder = new FactualResponderFragment();
        ft.add(responder, "RESTResponder");
    }

    Bundle bundle = new Bundle();
    bundle.putString("search_term", searchTerm);
    responder.setArguments(bundle);

    ft.commit();
}

public ArrayAdapter<String> getArrayAdapter() {
    return mAdapter;
} …
