Google maps in Android a simple overview

Google maps in Android a simple overview

Here we can see how a simple google map is obtained.in this map view we are using a zoom control.and use the methode setanimateto() to locate the userdefined locations.here is sample code for this,

                                                                                                             

JithudemoActivity.java

package a.b;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.MapView.LayoutParams;

import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;

public class JithudemoActivity extends MapActivity
{  
    MapView mapView;
    MapController mc;
    GeoPoint p;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mapView = (MapView) findViewById(R.id.mapView);
        LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);
        View zoomView = mapView.getZoomControls();

        zoomLayout.addView(zoomView,
            new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        mapView.displayZoomControls(true);

        mc = mapView.getController();
        String coordinates[] = {"8.487495", "76.948623"};
        double lat = Double.parseDouble(coordinates[0]);
        double lng = Double.parseDouble(coordinates[1]);

        p = new GeoPoint(
            (int) (lat * 1E6),
            (int) (lng * 1E6));

        mc.animateTo(p);
        mc.setZoom(17);
        mapView.invalidate();
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <com.google.android.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="0vNjDM-9Hpz8UM7pUWYJLvFptBpUpOqvQnV0S_g"
        />
        <LinearLayout android:id="@+id/zoom"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        />

</RelativeLayout>

change the view to  satellite view

 by using the following methode

  mapView.setSatellite(true);

JithudemoActivity.java

package a.b;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.MapView.LayoutParams;

import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;

public class JithudemoActivity extends MapActivity
{  
    MapView mapView;
    MapController mc;
    GeoPoint p;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mapView = (MapView) findViewById(R.id.mapView);
        LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);
        View zoomView = mapView.getZoomControls();

        zoomLayout.addView(zoomView,
            new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        mapView.displayZoomControls(true);

        mc = mapView.getController();
        String coordinates[] = {"8.487495", "76.948623"};
        double lat = Double.parseDouble(coordinates[0]);
        double lng = Double.parseDouble(coordinates[1]);

        p = new GeoPoint(
            (int) (lat * 1E6),
            (int) (lng * 1E6));

        mc.animateTo(p);
        mc.setZoom(17);
        mapView.invalidate();
     
     
        mapView.setSatellite(true);
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}
