Answer 1

I was facing the same issue in JakeWhartonViewPagerIndicatore along with SherlockFragments. Here is sample TestFragment with solved issue, thanks to Natalia for providing above solution. Your fragment may be a little different from mine.

Good Luck..!!

package com.example.vpiabstest;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import com.actionbarsherlock.app.SherlockFragment;

public class TestFragment extends SherlockFragment {
    private String mContent = "???";
    private String text;
    private static final String KEY_TAB_NUM = "key.tab.num";

    public static TestFragment newInstance(String text) {
        TestFragment fragment = new TestFragment();

        // Supply num input as an argument.
        Bundle args = new Bundle();
        args.putString(KEY_TAB_NUM, text);
        fragment.setArguments(args);


        return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        text = getString(R.string.tab_page_num) + mContent;

        View view = null;

        if(text.contains("2")) {
            view = inflater.inflate(R.layout.pinpoints_list, null);
        } else if(text.contains("1")) {
            view = inflater.inflate(R.layout.main_fragment_activity, null);
        } else {
            view = inflater.inflate(R.layout.activity_main, null);
            ((TextView)view.findViewById(R.id.text)).setText(text);
        }


        return view;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContent =  getArguments() != null ? getArguments().getString(KEY_TAB_NUM) : "???";
    }

    public void onDestroyView() {
        super.onDestroyView();

        // Your Programing skills goes here

        if(text == null || !text.contains("1")) {
            return;
        }

        // Do Not Miss this
        try {
            Fragment fragment = (getFragmentManager().findFragmentById(R.id.map_fragment));  
            FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
            ft.remove(fragment);
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Answer 2

You cannot inflate a layout into a fragment when that layout includes a fragment. Nested fragments are only supported when added to a fragment dynamically. More detail here!

Answer 3

I had the same problem. Try adding ...

android:name="com.mapfragmentexample.MapPageFragment"

... to fragment in the layout file!

Answer 4

Fragment fragment = (getChildFragmentManager().findFragmentById(R.id.mapview));
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();

Use this saves the day.

Answer 5

Try this

Maps fragment layout

<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
map:uiCompass="true"
map:mapType= "normal"
map:uiRotateGestures="true"
map:uiScrollGestures="true"
map:uiTiltGestures="true"
map:uiZoomControls="true"
map:uiZoomGestures="true" 
tools:context="the.package.name.of.mappagefragment.MapPageFragment" />

Map fragment class

public class MapPageFragment extends SupportMapFragment 
{

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{
    View rootView = super.onCreateView(inflater, container, savedInstanceState);
    if (rootView == null)
    {
        rootView = inflater.inflate(R.layout.map_fragment_layout, container, false);
    }
    return rootView;
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) 
{
    super.onViewCreated(view, savedInstanceState);
}
}

Use intent flags:

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

when calling main activity.
