Populate spinners using object returned by soap web service in android. Using string array as response from .net web service.

Populate the spinner with response from the web service . Where the response is in string array format.

Step 1: Create new project and in your layout file place a spinner.

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"
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=".MainActivity" >

<Spinner
android:id="@+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp" />

</RelativeLayout>

Step 2: Add uses permission Internet in your project manifest file.

AndroidManifest.xml:

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

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET"/>

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

</manifest>

Step 3:Include the KSOAP2 jar file in to your project.
Right click project ⇒ Properties ⇒ Java build path ⇒ Libraries Tab ⇒ Add External Jars ⇒ browse and add KSOAP2 Jar file.

Step 4: Then in your main class copy this code.

MainActivity.java :

package com.exam.district;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class MainActivity extends Activity {

String list[];
boolean exc=false;

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

new addassdist().execute();
}

class addassdist extends AsyncTask<Void, Void, Void> {

private final ProgressDialog dialog = new ProgressDialog(MainActivity.this);

private final String SOAP_ACTION = "http://tempuri.org/GetDistrict";
private final String METHOD_NAME = "GetDistrict";
private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://192.160.1.1/district/service.asmx";

@Override
protected void onPreExecute() {
this.dialog.setMessage("Loading data");
this.dialog.show();
}

@Override
protected Void doInBackground(Void... unused) {

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(Request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject response = (SoapObject) envelope.getResponse();

System.out.println("response"+response);
int intPropertyCount = response.getPropertyCount();
list= new String[intPropertyCount];

for (int i = 0; i < intPropertyCount; i++)
{
list[i] = response.getPropertyAsString(i).toString();
}
}

catch (Exception e) {
exc=true;
e.printStackTrace();
}
return null;
}

@Override
protected void onPostExecute(Void result) {

if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
if(exc)
{
Toast.makeText(MainActivity.this,"Error" , Toast.LENGTH_LONG).show();
}
else{
spinner();
exc=false;
}
}
}

public void spinner(){

Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);

ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, list);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onNothingSelected(AdapterView<?> parent) {

}

@Override
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
// your code
}
});
}

@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;
}
}
