Populate spinners using object returned by soap web service in android.

Here we populate two spinners with strings returned from soap object web service depend upon item selected in first spinner we call the second service and display values in second spinner.

If your web service response is string array and you need to populate only one spinner check this link

Step 1: Design your layout file. Here I've given simple design with two spinners.

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" >

<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="20dp"
android:layout_marginTop="25dp"
android:text="@string/country"
android:textAppearance="?android:attr/textAppearanceLarge" />

<Spinner
android:id="@+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginTop="25dp" />

<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/spinner1"
android:layout_below="@+id/spinner1"
android:layout_marginTop="26dp"
android:text="@string/state"
android:textAppearance="?android:attr/textAppearanceLarge" />

<Spinner
android:id="@+id/spinner2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView2"
android:layout_below="@+id/textView2"
android:layout_marginTop="26dp" />

</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.blog"
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.blog.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: create a new class file in your package and name it as Bean.

Bean.java:

package com.exam.twospinner;

import java.util.Hashtable;
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;

public class Bean implements KvmSerializable
{
public String Country;
public String State;

public Bean(){}

public Bean(String Country,String State) {
this.Country= Country;
this.State=State;
}

@Override
public Object getProperty(int arg0) {
switch(arg0)
{
case 0:
return Country;
case 1:
return State;
}
return null;
}

@Override
public int getPropertyCount() {
return 2;
}
@Override

public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {
switch(index)
{
case 0:
info.type = PropertyInfo.STRING_CLASS;
info.name = "Country";
break;
case 1:
info.type = PropertyInfo.STRING_CLASS;
info.name = "State";
break;
default:
break;
}
}

@Override
public void setProperty(int index, Object value) {
switch(index)
{
case 0:
Country= value.toString();
break;
case 1:
State= value.toString();
break;
default:
break;
}
}
}

Step 5: Then in your main class copy this code.

MainActivity.java :

package com.exam.blog;

import java.io.IOException;
import java.util.Arrays;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
