A. Output will be like this

 ******* When you click on a particular location it will show you a default marker and store this location to DataBase like this .... It will show you a Toast Also....

B. Java Codes

1. DataBase Handler class    LocationsDB.java is as 

package com.exam.ravi.googlemapex1;

import android.content.ContentValues;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class LocationsDB extends SQLiteOpenHelper {

       private static String DBNAME = "locationDB";

      private static int VERSION = 1;


    public static final String ROW_ID = "_id";


    public static final String LAT = "lat";
      public static final String LNG = "lng";
    public static final String ZOOM = "zom";

    private static final String DB_TABLE = "loc";

    private SQLiteDatabase mDB;
    public LocationsDB(Context context) {
        super(context, DBNAME, null, VERSION);
        this.mDB = getWritableDatabase();
    }
    @Override    public void onCreate(SQLiteDatabase db) {
        String sql =     "create table " + DB_TABLE + " ( " +
                ROW_ID + " integer primary key autoincrement , " +
                LNG + " double , " +
                LAT + " double , " +
                ZOOM + " text " +
                " ) ";
        db.execSQL(sql);
    }

   
    public long insert(ContentValues contentValues){
        long rowID = mDB.insert(DB_TABLE, null, contentValues);
        return rowID;
    }

    @Override

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    }

}

2.  MainActivity is as   named as AddLoc.java

package com.exam.ravi.googlemapex1;

import android.content.ContentValues;
import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class AddLoc extends AppCompatActivity  implements OnMapReadyCallback  {

        GoogleMap gMap;
        Context cob = this;
        @Override        protected void onCreate (Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
            SupportMapFragment mapFragment = (SupportMapFragment) 

                     getSupportFragmentManager()
                    .findFragmentById(R.id.map);
            mapFragment.getMapAsync(this);

    }
    @Override    public void onMapReady(GoogleMap googleMap)
    {
        gMap = googleMap;
        LatLng jaipur = new LatLng(26.923952,75.826743);
        CameraPosition cameraPosition = CameraPosition.builder()
         .zoom(17).tilt(20).bearing(90).target(jaipur).build();
         gMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
            gMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
            @Override            public void onMapClick(LatLng point) {

                drawMarker(point);   // Draw marker

                 ContentValues contentValues = new ContentValues();
                // get  & set with contentvalues

                 contentValues.put(LocationsDB.LAT, point.latitude);
                contentValues.put(LocationsDB.LNG, point.longitude);
                contentValues.put(LocationsDB.ZOOM, gMap.getCameraPosition().zoom);
                LocationsDB lb = new LocationsDB(cob);
                // Storing the latitude, longitude and zoom level to SQLite database

                long row = lb.insert(contentValues);
                if(row>0)
                Toast.makeText(cob, "Your Location Inserted Successfully...." , 

                                               Toast.LENGTH_SHORT).show();
                else

             Toast.makeText(cob, "Something Wrong...", Toast.LENGTH_SHORT).show();

            }
        });
    }
    private void drawMarker(LatLng point){
               MarkerOptions markerOptions = new MarkerOptions();
                 markerOptions.position(point);
                gMap.addMarker(markerOptions);
    }

}
