implementation 'com.google.android.gms:play-services-maps:15.0.1'



Step 10 : Add Permission And GoogleMap Key Add In AndroidManifest.xml File

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.bhaumik.googlemapsdemo">
    <!--
         The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
         Google Maps Android API v2, but you must specify either coarse or fine
         location permissions for the 'MyLocation' functionality. 
    -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <!--

        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="@string/google_maps_key" />

        <activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>


Step 11 : Add MapsActivity.xml File Design

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapsActivity" />



Step 12 : MapsActivity.java File

package com.example.bhaumik.googlemapsdemo;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}



Step 13 : Now You Can Run And Test Show On Google Maps.

Gridview in Android Example

What is GridView ?

GridView layout is a use to show data in grid layout.GridView is a ViewGroup that displays items in a two-dimensional, scrollable grid.In this layout is show row and column item in gridview.Gridview is use to BaseAdapter.GridView is a ViewGroup that displays items in a two-dimensional, scrollable grid. GridView is mainly useful when we want show data in grid layout like displaying images or icons.This layout can be used to build applications like image viewer, audio or video players in order to show elements in grid view.

        android:gravity="center"
        android:stretchMode="columnWidth" >

    </GridView>

</RelativeLayout>

What is BaseAdapter ?

Base Adapter. Adapter is a bridge between UI and data source, It helps us to fill data in the UI components.Common base class of common implementation for an Adapter that can be used in both ListView (by implementing the specialized ListAdapter interface) and Spinner (by implementing the specialized SpinnerAdapter interface).

MyAdapter.java

package com.example.bhaumik.gridviewdemo;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class MyAdapter extends BaseAdapter{

    Context mContext;

    int img[] = {R.drawable.img_1,R.drawable.img_2,R.drawable.img_3,R.drawable.img_4,R.drawable.img_5,R.drawable.img_6,R.drawable.img_7};

    public MyAdapter(Context mContext) {
        this.mContext = mContext;
    }

    @Override
    public int getCount() {
        return img.length;
    }

    @Override
    public Object getItem(int i) {
        return img[i];
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView = new ImageView(mContext);
        imageView.setImageResource(img[position]);
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);

        return imageView;
    }
}

MainActivity.java

package com.example.bhaumik.gridviewdemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.GridView;

public class MainActivity extends AppCompatActivity {

    GridView gridView;

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

        gridView = findViewById(R.id.grid_view);

        gridView.setAdapter(new MyAdapter(MainActivity.this));

    }
}

Expandable Listview in Android Example

Android, ExpandableListView is a View that shows items in a vertically scrolling two level list. Different from the listview by allowing two level groups which can individually be expanded to show.Expandable listview is a parent and childview to expand to click parent view to display childview in android.

    android:layout_height="match_parent"
    tools:context="com.bhaumik.expandablelistwithactivity.MainActivity"
    android:background="@color/MainActivityBackground">



    <ExpandableListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/expand_view" />

</RelativeLayout>

Create XML File to Parent Item Display in Layout

PrentItem.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"

        android:layout_height="wrap_content"
        android:textColor="@color/WhiteColor"
        android:text="Parent Item"
        android:textSize="20dp"
        android:padding="5dp"
        android:layout_marginLeft="20dp"/>
</LinearLayout>

Create XML Layout file to Child Item in Listview

ChildItem.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
