Question

Hi there I need help using Gauss' formula to find out what the Day(mon-fri) of the week is selected by the use of spinners and an EditText box. Once calculated I need it to display in a textbox called textView. The button is used to be an event to calculate once clicked.

Here Is my code thus far.

package com.example.daycalculator;

import java.util.ArrayList;

import java.util.List;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.ArrayAdapter;

import android.widget.Button;

import android.widget.Spinner;

import android.widget.Toast;

import android.widget.EditText;

public class MainActivity extends Activity {

private Spinner spinner1, spinner2;

private EditText EditText;

private Button btnSubmit;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

addItemsOnSpinner2();

addListenerOnButton();

addListenerOnSpinnerItemSelection();

}

// add items into spinner dynamically

public void addItemsOnSpinner2() {

spinner2 = (Spinner) findViewById(R.id.day);

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

list.add("1"); list.add("2");list.add("3");list.add("4");list.add("5");list.add("6");list.add("7");

list.add("8");list.add("9");list.add("10");list.add("11");list.add("12");list.add("13");list.add("14");

list.add("15");list.add("16");list.add("17");list.add("18");list.add("19"); list.add("20");list.add("21");

list.add("22");list.add("23");list.add("24");list.add("25");list.add("26");list.add("27");

list.add("28");list.add("29");list.add("30");list.add("31");

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

android.R.layout.simple_spinner_item, list);

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

spinner2.setAdapter(dataAdapter);

}

public void addListenerOnSpinnerItemSelection() {

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

spinner1.setOnItemSelectedListener(new CustomOnItemSelectedListener());

}

// get the selected dropdown list value

public void addListenerOnButton() {

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

spinner2 = (Spinner) findViewById(R.id.day);

setEditText((EditText) findViewById(R.id.year));

btnSubmit = (Button) findViewById(R.id.btnSubmit);

btnSubmit.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Toast.makeText(MainActivity.this,

"OnClickListener : " +

" Spinner 1 : "+ String.valueOf(spinner1.getSelectedItem()) +

" Spinner 2 : "+ String.valueOf(spinner2.getSelectedItem()),

Toast.LENGTH_SHORT).show();

}

});

}

public EditText getEditText() {

return EditText;

}

public void setEditText(EditText editText) {

EditText = editText;

}

}

A typical application is to calculate the day of the week on which someone was born or any other specific event occurred.
