Android 使用TabLayout和ViewPager挂起嵌套片段中的所有线程，应用程序将在没有任何崩溃对话框的情况下关闭

有一个

main活动

，它有各种

片段

，其中有使用自定义

TabLayout

和

ViewPager

的嵌套片段。嵌套片段的每个

片段都使用
WebServices
将数据显示到
ListView

其中一个片段如下：

public class IndicesFragment extends android.support.v4.app.Fragment {

public static IndicesFragment newInstance() {
    return new IndicesFragment();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.equity_activity, container, false);
    act = this.getActivity();
    return view;
}


public void onActivityCreated(Bundle savedInstanceState1) {
    super.onActivityCreated(savedInstanceState1);
    setHasOptionsMenu(true);
    list = (ListView) view.findViewById(R.id.list_equity);
    if (Utils.isNetworkAvailable(getActivity())) {
        if (catListDao.size() > 0) {
            adapter = new AdvisorsAdapter(act, R.layout.custom_equity, catListDao, 0);
            list.setAdapter(adapter);
        } else {
            if (!isViewShown) {
                new FetchAllData(getActivity(), 3).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
            }
        }
    } else {
        CustomToast toast = new CustomToast(getActivity(), "There is no internet connection!");
    }
}

@Override
public void onResume() {
    super.onResume();
    Constants.check_fragment_visible = 1;
    if (Constants.check_reload) {
        if (Utils.isNetworkAvailable(getActivity())) {
            new FetchAllData(getActivity(), 3).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
        } else {
            CustomToast toast = new CustomToast(getActivity(), "There is no internet connection!");
        }
    }
    if (adapter != null) adapter.notifyDataSetChanged();

}

当我们从一个
Fragment
更改
Activity
时，我的应用程序会在没有任何
对话框的情况下崩溃，当我们从另一个
MainActivity
片段调用这个嵌套片段时，它会在那里冻结，嵌套片段的片段会在那里突然打开。挂起线程的堆栈跟踪如下所示：

您有内存问题。您可以尝试各种策略来帮助最小化冲突，例如隐藏用户看不到的片段的根视图，以及编写高效的代码。您有内存问题。您可以尝试各种策略来帮助最小化冲突，例如隐藏用户看不到的片段的根视图，以及编写高效的代码。
