3. Write a code inside activity “onCreate()” methodpackage mobiapps.midterm.activity2;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.AdapterView;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Spinner;

import android.widget.TextView;

public class MidtermActivity2Activity extends Activity implements OnClickListener{

/** Called when the activity is first created. */

Button btncalculate,btnclose;

EditText etname, etsss, ettax, etpagibig, etphilhealth;

Spinner spposition;

TextView tvrate;

double rate,salary,sss,tax,pagibig,philhealth,deduction;

String sname,sposition;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

spposition=(Spinner)findViewById(R.id.idposition);

btncalculate=(Button)findViewById(R.id.idcalculate);

btnclose=(Button)findViewById(R.id.idclose);

etname=(EditText)findViewById(R.id.idfname);

ettax=(EditText)findViewById(R.id.idtax);

etsss=(EditText)findViewById(R.id.idsss);

etpagibig=(EditText)findViewById(R.id.idpagibig);

etphilhealth=(EditText)findViewById(R.id.idphilhealth);

tvrate=(TextView)findViewById(R.id.idrate);

btncalculate.setOnClickListener(this);

spposition.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

public void onItemSelected(AdapterView<?> arg0, View arg1,

int arg2, long arg3) {

// TODO Auto-generated method stub

if (spposition.getSelectedItem().toString().equalsIgnoreCase("Manager"))

rate=Double.parseDouble("30000");

else if (spposition.getSelectedItem().toString().equalsIgnoreCase("Regular"))

rate=Double.parseDouble("20000");

else if (spposition.getSelectedItem().toString().equalsIgnoreCase("Casual"))

rate=Double.parseDouble("8000");

tvrate.setText(String.valueOf(rate));

}

public void onNothingSelected(AdapterView<?> arg0) {

// TODO Auto-generated method stub

}

});

}

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()){

case R.id.idcalculate:

tax=Double.parseDouble(ettax.getText().toString());

sss=Double.parseDouble(etsss.getText().toString());

pagibig=Double.parseDouble(etpagibig.getText().toString());

philhealth=Double.parseDouble(etphilhealth.getText().toString());

deduction =tax + sss + pagibig + philhealth;

salary=rate-deduction;

sname=etname.getText().toString();

sposition=spposition.getSelectedItem().toString();

Bundle b = new Bundle();

b.putString("k_name", sname);

b.putString("k_position", sposition);

b.putString("k_salary", String.valueOf(salary));

Intent i = new Intent("mobiapps.midterm.activity2.DISPLAYOUTPUT");

i.putExtras(b);

startActivity(i);

break;

}

4. To add java file. Right package name, go to new the select class.

package mobiapps.midterm.activity2;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class DisplayOutput extends Activity{

TextView vpos, vname, vsalary;

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.display);

vname = (TextView) findViewById(R.id.tvname);

vpos = (TextView) findViewById(R.id.tvposition);

vsalary = (TextView) findViewById(R.id.tvsalary);

Bundle b = getIntent().getExtras();

String s_name = b.getString("k_name");

String s_position = b.getString("k_position");

String s_salary = b.getString("k_salary");

vname.setText(s_name);

vpos.setText(s_position);

vsalary.setText(s_salary);

}
