Remove a single marker from Google Maps Android API V2 on clicking InfoWindow

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="17" />
   
   
    <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>

Step 5 :- Open MainActivity.java

package com.mapv2.demo;

import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

import com.google.android.gms.common.ConnectionResult;

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 Google Play availability status
        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());

        // Showing status
        if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available

            int requestCode = 10;
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
            dialog.show();

        }else { // Google Play Services are available          

            // Getting reference to the SupportMapFragment of activity_main.xml
            SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

            // Getting GoogleMap object from the fragment
            googleMap = fm.getMap();

            // Enabling MyLocation Layer of Google Map
            googleMap.setMyLocationEnabled(true);
           
            // Setting click event handler for map
            googleMap.setOnMapClickListener(new OnMapClickListener() {
               
                @Override
                public void onMapClick(LatLng point) {
                    // Draw the marker at the taped position
                    drawMarker(point);
                }
            });
           
           
            // Setting click event handler for InfoWIndow
            googleMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
               
                @Override
                public void onInfoWindowClick(Marker marker) {
                    // Remove the marker
                    marker.remove();                   
                }
            });           
        }
    }
   
   
    private void drawMarker(LatLng point){
        // Creating an instance of MarkerOptions
        MarkerOptions markerOptions = new MarkerOptions();

        // Setting latitude and longitude for the marker
        markerOptions.position(point);
       
        // Setting snippet for the InfoWindow
        markerOptions.snippet("Tap here to remove this marker");
       
        // Setting title for the InfoWindow
        markerOptions.title("Marker Demo");

        // Adding marker on the Google Map
        googleMap.addMarker(markerOptions);        
    }
   

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