package com.murali.Dial;

import android.app.Activity;

import android.content.Intent;

import android.net.Uri;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

public class DialActivity extends Activity {

       

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

         setContentView(R.layout.main);

        

      final EditText EDtxt=(EditText) findViewById(R.id.txtNo);

            Button Dial=(Button) findViewById(R.id.Dial_button);

        

            Dial.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                       

                        String mNumber=EDtxt.getText().toString();

                       

// This is Intent for Starting Dail Activity...........................            

                       

Intent dailintent=new Intent(Intent.ACTION_DIAL,Uri.parse("tel:"+mNumber));

                       

startActivity(dailintent);

                       

                  }

            });

       }

}
