Hier gibt es nur Code Schnipsel zum Kopieren ohne Erklärung

Neue Activity[Bearbeiten]

MyNameActivity.java // Class
activity_my_name.xml // Layout File
AndroidManifest.xml
strings.xml

Activity Class[Bearbeiten]

package de.webmynet.android.myappname;

import android.app.Activity;
import android.os.Bundle;

public class MyNameActivity extends Activity{

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

Buttons verdrahten[Bearbeiten]

import android.widget.Button;
public class MyNameActivity extends Activity implements OnClickListener {
	Button b1,b2;
...
		b1 = (Button)findViewById(R.id.b1); 
		b2 = (Button)findViewById(R.id.b2); 
		b1.setOnClickListener(this); 
		b2.setOnClickListener(this);
...
	@Override
	public void onClick(View v) {
		int id = v.getId();
		Intent i = null;
		switch (id){
		case R.id.b1:
			i = new Intent(this,OtherNameActivity.class);
			break;
		case R.id.b2:
			i = new Intent("de.webmynet.appname.OTHERNAME");//Variant with Manifest Activity Name
			break;

		default:
			break;
		}
		startActivity(i);
	}

Map View[Bearbeiten]

Google API Key bereithalten[Bearbeiten]

Map Fragment zur Activity hinzufügen[Bearbeiten]

Im Layout File 

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

oder direkt in der Activity 

mMapFragment = MapFragment.newInstance();
 FragmentTransaction fragmentTransaction =
         getFragmentManager().beginTransaction();
 fragmentTransaction.add(R.id.my_container, mMapFragment);
 fragmentTransaction.commit();

Handle für die Karte[Bearbeiten]

private GoogleMap mMap;
...
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

Verfügbarkeit testen[Bearbeiten]

In onResume (evtl. auch onCreate) Testen ob die Karte verfügbar ist. 

private void setUpMapIfNeeded() {
    // Do a null check to confirm that we have not already instantiated the map.
    if (mMap == null) {
        mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                            .getMap();
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            // The Map is verified. It is now safe to manipulate the map.

        }
    }
}

Map Optionen[Bearbeiten]

Map Type[Bearbeiten]

GoogleMap map;
...
// Sets the map type to be "hybrid"
map.setMapType(GoogleMap.MAP_TYPE_HYBRID);

MAP_TYPE_NORMAL: Basic map with roads.
MAP_TYPE_SATELLITE: Satellite view with roads.
MAP_TYPE_TERRAIN: Terrain view with roads.

Optionen[Bearbeiten]

Optionen im Layout File[Bearbeiten]

<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="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"
  map:cameraBearing="112.5"
  map:cameraTargetLat="-33.796923"
  map:cameraTargetLng="150.922433"
  map:cameraTilt="30"
  map:cameraZoom="13"
  map:mapType="normal"
  map:uiCompass="false"
  map:uiRotateGestures="true"
  map:uiScrollGestures="false"
  map:uiTiltGestures="true"
  map:uiZoomControls="false"
  map:uiZoomGestures="true"/>

Optionen über Programmierung[Bearbeiten]

GoogleMapOptions options = new GoogleMapOptions();

options.mapType(GoogleMap.MAP_TYPE_SATELLITE)
    .compassEnabled(false)
    .rotateGesturesEnabled(false)
    .tiltGesturesEnabled(false);

Optionen im Konstruktor mit übergeben: 

MapFragment.newInstance(GoogleMapOptions options)

oder bei MapViews: 

MapView(Context, GoogleMapOptions)
