Android - Implementazione di mappe v2 nel cassetto di navigazione

Ho provato a unire due programmi demo Android, ma non sono riuscito a farlo correttamente.Android - Implementazione di mappe v2 nel cassetto di navigazione

Ho provato e cercato per diversi modi, ma non riuscivo a capirlo. Per favore potete aiutarmi?

Ecco il mio messaggio di errore:

Ecco il mio codice sorgente, ho cambiato solo questa funzione:

private void selectItem(int position) { 
    // update the main content by replacing fragments 

    Fragment mapfragment = new BasicMapActivity(); 

    Fragment fragment = new PlanetFragment(); 
    Bundle args = new Bundle(); 
    args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position); 
    fragment.setArguments(args); 

    mapfragment.getFragmentManager(); 
    FragmentManager fragmentManager = getSupportFragmentManager(); 
    fragmentManager.beginTransaction().replace(R.id.content_frame, mapfragment).commit(); 

    // update selected item and title, then close the drawer 
    mDrawerList.setItemChecked(position, true); 
    setTitle(mPlanetTitles[position]); 
    mDrawerLayout.closeDrawer(mDrawerList); 
}

Ecco la mia mappa frammento:

public class BasicMapActivity extends Fragment { 
/** 
* Note that this may be null if the Google Play services APK is not available. 
*/ 
private GoogleMap mMap; 

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

} 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    //setUpMapIfNeeded(); 
    View rootView = inflater.inflate(R.layout.basic_demo, container, false); 
    setUpMapIfNeeded(); 
    return rootView; 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    setUpMapIfNeeded(); 
} 

private void setUpMapIfNeeded() { 
    // Do a null check to confirm that we have not already instantiated the map. 
    if (mMap == null) { 
     // Try to obtain the map from the SupportMapFragment. 
     mMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 
     // Check if we were successful in obtaining the map. 
     if (mMap != null) { 
      setUpMap(); 
     } 
    } 
} 

private void setUpMap() { 
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); 
} 
}

anche il file xml per BasicMapActivity:

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/map" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
class="com.google.android.gms.maps.SupportMapFragment"/>

EDIT:

Ecco XML del programma principale:

<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<!-- As the main content view, the view below consumes the entire 
    space available using match_parent in both dimensions. --> 
<FrameLayout 
    android:id="@+id/content_frame" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" /> 


<!-- android:layout_gravity="start" tells DrawerLayout to treat 
    this as a sliding drawer on the left side for left-to-right 
    languages and on the right side for right-to-left languages. 
    The drawer is given a fixed width in dp and extends the full height of 
    the container. A solid background is used for contrast 
    with the content view. --> 
<ListView 
    android:id="@+id/left_drawer" 
    android:layout_width="240dp" 
    android:layout_height="match_parent" 
    android:layout_gravity="start" 
    android:choiceMode="singleChoice" 
    android:divider="@android:color/transparent" 
    android:dividerHeight="0dp" 
    android:background="#111"/> 
</android.support.v4.widget.DrawerLayout>

Finché il mio manifesto:

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.android.navigation" 
android:versionCode="1" 
android:versionName="1.0">

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

</application> 

</manifest>

Qualcuno potrebbe darmi un suggerimento? Sono stato bloccato qui per 2-3 giorni.

Grazie mille!

si dovrebbe pubblicare il manifest :) –

Ho modificato il mio post, in modo da poter avere una visione chiara di l'intero programma. Grazie! –

API_KEY Deve essere in ;) –

tuo issu è semplice

l'API Key deve essere all'interno del tag Application, anche si dovrebbe mettere alla fine

Esempio:

<application 
    android:label="@string/app_name" 
    android:icon="@drawable/ic_launcher" 
    android:theme="@android:style/Theme.Holo.Light.DarkActionBar" 
    android:allowBackup="true"> 

    <activity 
     android:name=".MainActivity" 
     android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <meta-data android:name="com.google.android.maps.v2.API_KEY" 
    android:value="AIzaSyDJbPX63ZJni6sbzNxaFvFUCnYLb7-9o28"/> 

</application>

Caused by: java.lang.RuntimeException: API key not found. Check that <meta-data 
android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> 
is in the <application> element of AndroidManifest.xml

Ottenere una chiave API valida. Con questo non è possibile eseguire una mappa V2 nella tua app. Ecco il doc come si può ottenere uno.

Un altro errore si verifica nel layout xml per BasicMapActivity alla riga n. 18. Per favore pubblica questo XML nella tua domanda.

Ciao, Steve. In realtà ho seguito il sito web che hai fornito e ho usato la chiave di debug per generare la chiave API, ma l'errore è rimasto. Ho anche aggiornato il mio codice in modo da poter avere una visione chiara. Grazie!! –

Nel messaggio di errore si aveva due problemi:

1.- "android.view.InflateException: riga di file XML binario # 18: Errore durante il gonfiaggio del frammento di classe"

2.- "java.lang.RuntimeException: chiave API non trovata. Controllare che sia nell'elemento di AndroidManifest.xml"

La soluzione offerta da 'yume117' risolto il numero 2, ma penso che il problema 'gonfiaggio frammento di classe' è dovuto al file XML per BasicMapActivity.

Invece di un "frammento" all'interno del "layout" si avrebbe bisogno di passare a qualcosa di simile:

<com.google.android.gms.maps.MapView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/map" 
android:layout_width="match_parent" 
android:layout_height="match_parent" />

Inoltre sarebbe necessario cambiare la classe Java. In questo url è un esempio per controllare questo (è in spagnolo ma penso che il codice sia comprensibile): https://groups.google.com/forum/#!msg/desarrolladores-android/1cvqPm0EZZU/9srw_9feamUJ
