1) Create your project name in eclipse.
2)  In activity_main.xml

Android sample Project Part 3

Android Sample Project Part - 3

Android Sample Project Part - 3

In  this section you will know more android sample project , and this part we will learn more about xml file.

In this part we will store variable name and values in String.xml file in android sample project .

To store variable and values in string.xml to ,go to android project 

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <string name="app_name">salary</string>

    <string name="action_settings">Settings</string>

     <string name="SalaryTax">Tax payment</string>

      <string name="Salary">Salary</string>

      <string name="CalculateTax">Calcualte</string>

     <string name="NetSalary">balance</string>

      <string name="Tax">Tax</string>

      <string name="introductionTaz">1$ = 4000 Riels</string>

    

</resources>

You saw some variable and values stores in string.xml file and ti was used activity_main.xml 

Example:1

android:text="@string/SalaryTax" ,also you can call to use it in MainActivity.java like this 

Example:2

Toast.makeText(MainActivity.this, getString(R.string.SalaryTax, comp, guesses), 
            Toast.LENGTH_LONG).show();

Android Sample Project Part - 4

In this section you will know more about MainActivity.java and Concept in android sample project 

In this app you will know how to declare variable and some conditions in Salary Tax.

There are  some conditions that we will to do it in MainActivity.java

Monthly salary (Riels)	Rate
0 - 800,000	0%
800,001 - 1,250,000	5%
1,250,001 - 8,500,000	10%
8,500,001 - 12,500,000	15%
12,500,001 - upwards	20%

public class MainActivity extends Activity {

public Button CalculateTax;

public EditText Salary;

public TextView NetSalary;

public TextView Tax;

public double salarys, netsalary,tax = 0;

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

                //call method 

addOnclickListener();

}

private void addOnclickListener() {

// TODO Auto-generated method stub

CalculateTax = (Button)findViewById(R.id.btncal);

Salary = (EditText)findViewById(R.id.txtsalary);

NetSalary = (TextView)findViewById(R.id.lblnet);

Tax = (TextView)findViewById(R.id.lbltax);

CalculateTax.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

// TODO Auto-generated method stub

if(Salary.getText().toString().equals("")){

Toast.makeText(getApplicationContext(), "Please Fill in the salary", Toast.LENGTH_LONG).show();

}

else

{

salarys = Double.valueOf(Salary.getText().toString());

if(salarys>=0 && salarys<=800000){

netsalary = salarys ;

tax = 0;

}else if(salarys >= 800001 && salarys <= 1250000){

tax = (salarys *0.05)-40000;

netsalary = salarys -((salarys *0.05) - 40000);

}else if(salarys >=1250001 && salarys <= 8500000){

tax = (salarys *0.1)-102500;

netsalary  = salarys  - ((salarys  *0.1 ) - 102500);

}else if(salarys >= 8500001 && salarys <= 12500000){

tax = (salarys *0.15)-527500;

netsalary  = salarys - ((salarys *0.15)-527500);

}else {

tax = (salarys *0.2)-1152500;

DecimalFormat df = new DecimalFormat("00.00");

                   String myre = df.format(tax);

netsalary  = salarys - ((salarys *0.2)-1152500);

DecimalFormat dfo = new DecimalFormat("00.00");

                   String myreo = dfo.format(netsalary  );

}

}

String finaltax = String.valueOf(tax);

Tax.setText(" Pay tax = "+finaltax);

NetSalary.setText("Your Balance = "+ String.valueOf(netsalary  ));

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}

8,500,001 - 12,500,000	15%
12,500,001 - upwards	20%

Next tutorial we will create this sample android project.
