                }
            }
        });





    }
}

Step 3:- listdata.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="match_parent">

            android:layout_height="match_parent"
            android:id="@+id/list1"></ListView>
    </FrameLayout>


</LinearLayout>

Step 4: ListItem.java

package androidhubb.sqliteexample;

import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ListView;

import java.util.ArrayList;

/** * Created by Supriya on 8/31/2016. */public class ListData extends AppCompatActivity {
    ListView listView;
    SQLiteDatabase db;
    FloatingActionButton fab;
    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listdata);
        listView=(ListView)findViewById(R.id.list1);
        fab=(FloatingActionButton)findViewById(R.id.fab);

        db=openOrCreateDatabase("MyData3", Context.MODE_PRIVATE,null);
        onViewData();

        fab.setOnClickListener(new View.OnClickListener() {
            @Override            public void onClick(View view) {
                startActivity(new Intent(ListData.this,MainActivity.class));
            }
        });
    }
    public void onViewData(){
        ArrayList<String> listname=new ArrayList<String>();
        ArrayList<String> listPhone=new ArrayList<String>();
        ArrayList<String> listgender=new ArrayList<String>();
        listname.clear();
        listPhone.clear();
        listgender.clear();
        Cursor c=db.rawQuery("select * from MyTable3",null);
        while(c.moveToNext()){
            listname.add(c.getString(1));
            listPhone.add(c.getString(2));
            listgender.add(c.getString(3));
        }
        listView.setAdapter(new Adapter(ListData.this,listname,listPhone,listgender));

    }
}




Step:-5 adapter.xml

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

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Name"
        android:id="@+id/tvName"
        android:textSize="20sp"/>
    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Name"
        android:id="@+id/tvphone"
        android:textSize="20sp"/>
    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Name"
        android:id="@+id/tvgender"
        android:textSize="20sp"/>
</LinearLayout>


Step6:- AdapterList.java

package androidhubb.sqliteexample;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import java.util.ArrayList;

/** * Created by Supriya on 8/31/2016. */public class Adapter extends BaseAdapter {
    ArrayList<String> n,p,g;
    ListData l;
    LayoutInflater inflater;
    public Adapter(ListData data,ArrayList<String> name,ArrayList<String> phone,ArrayList<String> gender){
        this.l=data;
        this.n=name;
        this.p=phone;
        this.g=gender;
        this.inflater=LayoutInflater.from(data);
    }
    @Override    public int getCount() {
        return n.size();
    }

    @Override    public Object getItem(int i) {
        return null;
    }

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

    @Override    public View getView(int i, View view, ViewGroup viewGroup) {
        view=inflater.inflate(R.layout.adapter,null);
        TextView tvname=(TextView)view.findViewById(R.id.tvName);
        TextView tvnumber=(TextView)view.findViewById(R.id.tvphone);
        TextView tvgender=(TextView)view.findViewById(R.id.tvgender);
        tvname.setText(n.get(i));
        tvnumber.setText(p.get(i));
        tvgender.setText(g.get(i));
        return view;
    }
}

step 7;- For Floating Actionbar we have to add following in build.gradl

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.1.1'
    compile 'com.android.support:design:24.1.1'
}

Started Service Example in Android Studio 2.1.2

Code Verified on-
Android Studio 2.1.2

Step1:
Take a new Project and open activity_main.xml file. Coding will be like following.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical"
tools:context="androidhubb.setvices.MainActivity"
android:layout_margin="16dp"
android:gravity="center_vertical">

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Start Services"
android:onClick="onStart"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Stop Services"
android:onClick="onStop"/>
</LinearLayout>

Step 2:- To start a Bound Service we have to take another java MyService.java

package androidhubb.startedservice;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.widget.Toast;

/** * Created by Supriya on 8/24/2016. */public class MyService extends Service{

    @Override

public void onCreate() {
        super.onCreate();
    }

    @Override

 public int onStartCommand(Intent intent, int flags, int startId) {

        Toast.makeText(getApplicationContext(),"Service started",Toast.LENGTH_LONG).show();
        return START_STICKY;
    }

    @Override

public void onDestroy() {
        super.onDestroy();
        Toast.makeText(getApplicationContext(),"Service stoped",Toast.LENGTH_LONG).show();
    }

    @Nullable    @Override

 public IBinder onBind(Intent intent) {
        return null;
    }
}

3. MainActivity.java

package androidhubb.startedservice;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    @Override

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void onStart(View v){
        startService(new Intent(getApplicationContext(),MyService.class));
    }

    public void onStop(View v){
        stopService(new Intent(getApplicationContext(),MyService.class));
    }
}

        return null;
    }

    @Override

public void onCreate() {
        super.onCreate();
        mp=MediaPlayer.create(this,R.raw.sanam);
        mp.setLooping(true);
    }

    @Override

public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        mp.start();

Step2:-Click on File >New >New Project> SOAPExample

Step3:-Click on res>activity_main.xml and take 1TextView and 1 Spinner

Step 4:- activity_main.xml code will be like following.

<?xml version="1.0" encoding="utf-8"?>

<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"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="supriya.soap2.MainActivity">

<TextView

android:layout_width="match_parent"

android:text="Select Country"

android:id="@+id/textView" />

<Spinner

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:id="@+id/spinner"

android:layout_below="@+id/textView"

android:layout_alignParentLeft="true"

android:layout_alignParentStart="true"

android:layout_marginTop="58dp" />

</RelativeLayout>

Step 5:- Click to Download ksoap2 dependencies library After downloading extract the file and copy that library file and paste that in libs folder. app >libs >after paste right click on that ksoap2 file and select > set as library > ok

Step 6:- MainActivity.java code will be like following.

package supriya.soap2;

import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

import java.util.ArrayList;

public class    MainActivity extends AppCompatActivity {
    Spinner spnCountry;
    ProgressDialog pd;

    @Override

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

        //process dialoge coding...

pd=new ProgressDialog(MainActivity.this);
        pd.setMessage("Loading..");

        //id of Spinner..

spnCountry=(Spinner)findViewById(R.id.spinner);

        //array list...

ArrayList<String> list=new ArrayList<String>();
        list.clear();
        list.add("--Select--");
        list.add("India");
        list.add("US");


        //array adapter...

ArrayAdapter<String> adp=new ArrayAdapter<String>(getApplicationContext(),R.layout.spinback,list);
        spnCountry.setAdapter(adp);

        //spinner listner,.....

spnCountry.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                MyTask t=new MyTask(spnCountry.getSelectedItem().toString());
                t.execute();

            }

            @Override

public void onNothingSelected(AdapterView<?> parent) {

            }
        });
    }//closing of onCreate method......

    class MyTask extends AsyncTask<String,String,String>{
        //variables....

String setCountryName="";
        String getCitiesName="";

        //constructor.....

public  MyTask(String cName){
            this.setCountryName=cName;

        }
        @Override

protected void onPreExecute() {
            super.onPreExecute();
            pd.show();
        }

        @Override

protected String doInBackground(String... params) {
            AddEvent ae=new AddEvent();
            getCitiesName=ae.getResultOfCitiesName(setCountryName);
            return null;
        }

        @Override

protected void onPostExecute(String s) {
            super.onPostExecute(s);
            tostOutput(getCitiesName);
            pd.dismiss();
        }

        @Override

protected void onProgressUpdate(String... values) {
            super.onProgressUpdate(values);
        }
    }

//close MyTask class
    public void tostOutput(String result){
        Toast.makeText(getApplicationContext(),result,Toast.LENGTH_LONG).show();
    }
}

Step 6:- AddEvent.java code will be like following.


public class AddEvent {
    String NAMESPACE = "http://www.webserviceX.NET";
    String URL="http://www.webservicex.net/globalweather.asmx?wsdl";


    public String getResultOfCitiesName(String getAllCitiesName)
    {
        String SOAP_ACTION1 = "http://www.webserviceX.NET/GetCitiesByCountry";
        String METHOD_NAME1 = "GetCitiesByCountry";
        String result_="";
        SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME1);

        request.addProperty("CountryName",getAllCitiesName);

        SoapSerializationEnvelope envelope =new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
        envelope.dotNet = true;
        try        {
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
            //this is the actual part that will call the webservice         

androidHttpTransport.call(SOAP_ACTION1, envelope);

            // Get the SoapResult from the envelope body.            

SoapObject result = (SoapObject)envelope.bodyIn;
            if(result != null)
            {
                result_=result.getProperty(0).toString().trim();
            }
            else            {
                result_="no data found";
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result_;
    }
}

Step 6:-To give customlook to spineer add a xml file in layout folder  app > res > layout > right click on layout > new > layout resource file > spinback.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:textColor="#000000"
    android:minHeight="?android:attr/listPreferredItemHeightSmall" />
