        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         
        Button buttonStartDialog = (Button)findViewById(R.id.button_alert);
        buttonStartDialog.setOnClickListener(new Button.OnClickListener(){

A dialog showing a progress indicator and an optional text message or view. Only a text message or a view can be used at the same time.
More About the progress dialog and progress bar then visit the android developer site Progress Dialog.

Now lets start the coding about the progress dialog in android that will execute inside the doInBackground() of Asynctask till.

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;

Spinner

Hi Guys!!

Today I am sharing the code about the Spinner in android.
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 dropdown menu with all other available values, from which the user can select a new one.
For detail please visit android developer site Spinner.

So lets start the coding about the spinner in android.

activity_main.xml

MainActivity.java

package com.sunil.spinner;

 import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
 
public class MainActivity extends Activity {
  
 private static final String[] dayOfWeek =
  {"Sunday", "Monday", "Tuesday", "Wednesday",
   "Thursday", "Friday", "Saturday"};
  private ArrayAdapter adapter;
  
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Spinner spinner = (Spinner)findViewById(R.id.spinner);
         
        adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, dayOfWeek);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

   switch(id){
   case ID_TIMEPICKER:
    return new TimePickerDialog(this, timeSetListener, hour, minute, false);
   default:
    return null;
   }
 }
 private TimePickerDialog.OnTimeSetListener timeSetListener
  = new TimePickerDialog.OnTimeSetListener(){
  @Override
  public void onTimeSet(android.widget.TimePicker arg0, int arg1, int arg2) {
   // TODO Auto-generated method stub
   Toast.makeText(getBaseContext(), String.valueOf(arg1) + ":" + String.valueOf(arg2), Toast.LENGTH_LONG).show();

The client can customize whether only the spinners, or only the calendar view, or both to be displayed. Also the minimal and maximal date from which dates to be selected can be customized.
For detail about the Date Picker you can visit the android developer site Date Picker.

So lets start the coding about the date picker android.

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;

public class MainActivity extends Activity {
  
 private int year, month, day;
 static final int ID_DATEPICKER = 0;
  
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
   
     Button startDatePicker = (Button)findViewById(R.id.startdatepicker);
     startDatePicker.setOnClickListener(new Button.OnClickListener(){
 
   @Override

    // TODO Auto-generated method stub
    final Calendar c = Calendar.getInstance();
       year = c.get(Calendar.YEAR);
       month = c.get(Calendar.MONTH);
       day = c.get(Calendar.DAY_OF_MONTH);
       showDialog(ID_DATEPICKER);
   }});
 }
 
 @Override
 protected Dialog onCreateDialog(int id) {
  switch(id){
  case ID_DATEPICKER:
   return new DatePickerDialog(this, dateSetListener, year, month, day);
  default:
   return null;
  }
 }
  
 private DatePickerDialog.OnDateSetListener dateSetListener
   = new DatePickerDialog.OnDateSetListener(){
 
  @Override
  public void onDateSet(android.widget.DatePicker arg0, int arg1,int arg2, int arg3) {
 
      Toast.makeText(getBaseContext(), String.valueOf(arg1) + "/"  + String.valueOf(arg2+1) + "/"  + String.valueOf(arg3),Toast.LENGTH_LONG).show();
