问题


I am trying to use the latest Map API 2.0 provided for Android. I am using the Support Library as I want to support Android 2.2. Following is my code:

Main Activity class

public class MainActivity extends FragmentActivity {

    public FragmentManager fManager ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        fManager = getSupportFragmentManager();
        Button showMapButton = (Button) findViewById(R.id.showMapButton);
        showMapButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                loadMapFragment();
            }
        });
    }

    private void loadMapFragment() {
        MapPageFragment plotterFragment = new MapPageFragment();
        FragmentTransaction ft = fManager.beginTransaction();
        ft.replace(R.id.allFragmentsFrameLayout, plotterFragment);
        ft.addToBackStack(null);
        ft.commit();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

Main Activity layout file

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/showMapButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Show Map"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="30dp"
        android:layout_alignParentTop="true" />


    <FrameLayout
        android:id="@+id/allFragmentsFrameLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true">
        <!-- Put fragments dynamically -->
    </FrameLayout>

</RelativeLayout>

Map Fragment Class

public class MapPageFragment extends SupportMapFragment {

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

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

Map 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"
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    class="com.google.android.gms.maps.SupportMapFragment"
    map:uiCompass="true"
    map:mapType= "normal"
    map:uiRotateGestures="true"
    map:uiScrollGestures="true"
    map:uiTiltGestures="true"
    map:uiZoomControls="true"
    map:uiZoomGestures="true" />

            </intent-filter>
        </activity>

            android:value="AIzaSyA5FtIeLQ1gGUihZIZPQVi3Yz_0l4NG9PY"/>
    </application>

</manifest>

Everything is working fine for the first time. i.e. When I click on the Show Map button the map fragment gets loaded and displays the map. When I press back button, the map fragment is unloaded and I can see the Show Map button again.

I face an issue when I press the Show Map button again. I get the following error:

I am not getting where I am getting wrong or missing anything.


回答1:


You can fix this, if you delete all nested fragments in onDestroyView(). Don't know if it is a proper solution.

public void onDestroyView() {
   super.onDestroyView(); 
   Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));   
   FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
   ft.remove(fragment);
   ft.commit();
}

And inflating them as usual in onCreateView()

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map, container, false);
}



回答2:


You need to use getChildFragmentManager() to add SupportMapFragment not not through xml.

For "why", see official documentation: http://developer.android.com/about/versions/android-4.2.html#NestedFragments

Take a look at my answer here: https://stackoverflow.com/a/15512285/2183804




回答3:


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!




回答4:


Used this solution (similar to others):

public void onDestroyView() {

    FragmentManager fm = getActivity().getSupportFragmentManager();
    Fragment fragment = (fm.findFragmentById(R.id.map));

    if (fragment.isResumed()) {
        FragmentTransaction ft = fm.beginTransaction();
        ft.remove(fragment);
        ft.commit();
    }
    super.onDestroyView();
}

I had problems before using the if (fragment.isResumed).




回答5:


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.

Reference: Making ActionBarSherlock and ViewPagerIndicator play nice

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();
        }
    }
}



回答6:


Use dialog.SetContentView() method in your activity's onCreate() cause when we tring to load.

Dialog again it loads only dialog not the whole activity life cycle and leads it to exception of Duplicate id.

Try it.

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);
}
}



回答8:


I used Natalia response but at times broke the application. Use this one and it worked perfectly without breaking.

@Override
public void onDestroyView() {

  try{
    FragmentTransaction transaction = getSupportFragmentManager()
            .beginTransaction();

    transaction.remove(nestedFragment);

    transaction.commit();
  }catch(Exception e){
  }

    super.onDestroyView();
}

回答9:


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

Use this saves the day.




回答10:


Use intent flags:

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

when calling main activity.




回答11:


I had the same problem. Try adding ...

android:name="com.mapfragmentexample.MapPageFragment"

... to fragment in the layout file!
