Android: Wie man com.google.android.gms.maps.MapView implementiert, ohne eine Kartenaktivität zu verwenden

Question

Ich habe versucht, in einem linearen Layout zu implementieren, und dieses Layout gehört nicht zu einer MapActivity. Ich habe auch keinen fragment verwendet, um diesen Prozess zu implementieren.

Außerdem habe ich einen API-Schlüssel von der Google Developer Console erhalten und einige APIs aktiviert, die sich auf Standorte und Karten beziehen.

Das ist mein Android-Manifest in Android Studio ist,

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="sec.asdf_solutions.biz.security">

Das ist meine Tat ivity für obige Verfahren zu implementieren,

public class RosterActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { 

    //protected MapView mMapView; 

    android.support.v7.widget.AppCompatButton acceptButton; 
    android.support.v7.widget.AppCompatButton rejectButton; 
    private Context context; 

    private String token; 
    private long idLong; 
    private Response responseBody; 

    TextView rosterDateTextView; 
    TextView rosterStartTimeTextView; 
    TextView rosterEndTimeTextView; 
    TextView rosterLocationTextView; 

    View mainView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_roster); 

     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_roster); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setDisplayShowHomeEnabled(true); 

    } 

    @Override 
    public boolean onNavigationItemSelected(MenuItem item) { 
     return true; 
    } 

} 

Wichtiger Hinweis: Ich bin nicht MapActivity verwenden.

Haben Sie irgendwelche Ideen?

Answer 1

Per MapView's documentation:

Nutzer dieser Klasse müssen alle Lebenszyklus-Methoden aus der Aktivität oder Fragment mit diesem Blick auf die entsprechenden in dieser Klasse übermitteln. Insbesondere müssen Sie auf den folgenden Methoden weiter:

• onCreate (Bundle)
• onStart()
• onResume()
• onPause()
• OnStop()
• onDestroy (
)
• onSaveInstanceState()
• onLowMemory()

dass all MapFragment oder SupportMapFragment tut, ist nach vorn all diesen Rückrufen auf die MapView wenn Sie also, dass selbst arbeiten, gibt es keine Notwendigkeit, eine bestimmte übergeordnete Klasse haben.

Zum Beispiel:

MapView rosterMapView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_roster); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_roster); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setDisplayShowHomeEnabled(true); 

    rosterMapView = (MapView) findViewById(R.id.roster_map_view); 
    rosterMapView.onCreate(savedInstanceState); 
} 

@Override 
protected void onPause() {{ 
    super.onPause(); 
    rosterMapView.onPause(); 
} 

usw., usw. - jede Methode außer Kraft setzen und den Anruf auf Ihre MapView passieren.

Answer 2

Sie können diesen Weg versuchen.Auch sollten Sie Ihren API-Schlüssel nie veröffentlichen/zeigen. Versuche zu verstecken.

 <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 

       <fragment 
       android:id="@+id/map" 
       android:name="com.google.android.gms.maps.MapFragment" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" /> 
    </Linear Layout> 


    //finding xml view from xml layout 
      GoogleMap googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
