Customizing InfoWindow Contents in Google Map Android API V2 using InfoWindowAdapter

Step 1 :- Create New Android Project.



Step 2 :- Add Google-play-services_lib to your project.

Step 3 :- Open AndroidManifest.xml file.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mapv2.demo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />
   
    <permission
          android:name="com.mapv2.demo.permission.MAPS_RECEIVE"
          android:protectionLevel="signature"/>
   
       <uses-permission android:name="com.mapv2.demo.permission.MAPS_RECEIVE"/>
      
       <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   
    <uses-feature
          android:glEsVersion="0x00020000"
          android:required="true"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.mapv2.demo.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="AIzaSyCmX7SLVHXxU9pSqb2QbAOvdnjAGUulOrk"/>
       
    </application>

</manifest>

Step 4 :- Open activity_main.xml.

<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" >

    <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"/>

</RelativeLayout>


1.) info_window_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"   
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@color/bg_color" >
   
    <TextView
        android:id="@+id/tv_lat"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
   
    <TextView
        android:id="@+id/tv_lng"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
   
</LinearLayout>




Step 5 :- Open MainActivity.java

package com.mapv2.demo;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.GoogleMap.InfoWindowAdapter;
import com.google.android.gms.maps.GoogleMap.OnMapClickListener;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends FragmentActivity {
   
    GoogleMap googleMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        // Getting reference to the SupportMapFragment of activity_main.xml
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
       
        // Getting GoogleMap object from the fragment
        googleMap = mapFragment.getMap();
       
        // Setting a custom info window adapter for the google map       
        googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
           
            // Use default InfoWindow frame
            @Override
            public View getInfoWindow(Marker arg0) {               
                return null;
            }           
           
            // Defines the contents of the InfoWindow
            @Override
            public View getInfoContents(Marker arg0) {
               
                // Getting view from the layout file info_window_layout
                View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);
               
                // Getting the position from the marker
                LatLng latLng = arg0.getPosition();
               
                // Getting reference to the TextView to set latitude
                TextView tvLat = (TextView) v.findViewById(R.id.tv_lat);
               
                // Getting reference to the TextView to set longitude
                TextView tvLng = (TextView) v.findViewById(R.id.tv_lng);
               
                // Setting the latitude
                tvLat.setText("Latitude:" + latLng.latitude);
               
                // Setting the longitude
                tvLng.setText("Longitude:"+ latLng.longitude);
               
                // Returning the view containing InfoWindow contents
                return v;
               
            }
           
        });
       
       
        // Adding and showing marker while touching the GoogleMap
        googleMap.setOnMapClickListener(new OnMapClickListener() {
           
            @Override
            public void onMapClick(LatLng arg0) {
                // Clears any existing markers from the GoogleMap
                googleMap.clear();
               
                // Creating an instance of MarkerOptions to set position
                MarkerOptions markerOptions = new MarkerOptions();
               
                // Setting position on the MarkerOptions
                markerOptions.position(arg0);               
               
                // Animating to the currently touched position
                googleMap.animateCamera(CameraUpdateFactory.newLatLng(arg0));   
               
                // Adding marker on the GoogleMap
                Marker marker = googleMap.addMarker(markerOptions);
               
                // Showing InfoWindow on the GoogleMap
                marker.showInfoWindow();
               
            }
        });
       
       
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}
