Adding data to a Spinner

Adding data to a Spinner

Hi..friends,Today i want to show you how to add data to a spinner.Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a drop down menu with all other available values, from which the user can select a new one.You can get idea by looking below code.

package com.project.androm.dinuka;

import java.util.ArrayList;

import java.util.List;

import com.project.androm.R;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ArrayAdapter;

import android.widget.Button;

import android.widget.Spinner;

import android.widget.AdapterView.OnItemSelectedListener;

public class Mdl_CategorySelection extends Activity implements

OnItemSelectedListener {

String sem = "";

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.mdl_categoryselection);

// Spinner element

Spinner spinnerSem = (Spinner) findViewById(R.id.spinnerSemesterSub);

spinnerSem.setOnItemSelectedListener(this);

// Spinner Drop down elements

List<String> categories1 = new ArrayList<String>();

categories1.add("1st Semester");

categories1.add("2nd Semester");

// Creating adapter for spinner

ArrayAdapter<String> dataAdapter1 = new ArrayAdapter<String>(this,

android.R.layout.simple_spinner_item, categories1);

// Drop down layout style - list view with radio button

dataAdapter1

.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

// attaching data adapter to spinner

spinnerSem.setAdapter(dataAdapter1);

sem = spinnerSem.getSelectedItem().toString();

public void onItemSelected(AdapterView<?> parent, View view, int position,

long id) {

// On selecting a spinner item

String item = parent.getItemAtPosition(position).toString();

if (item.contains("Year")) {

year = item;

} else if (item.contains("Semester")) {

sem = item;

}

}

public void onNothingSelected(AdapterView<?> arg0) {

// TODO Auto-generated method stub

}

}
