Designing Part:

Layout file: Main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1">
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
 <EditText android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:id="@+id/txtNo"
    android:layout_toLeftOf="@+id/Dial_button">
    </EditText>
 <Button android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:layout_alignBaseline="@+id/editText1"
    android:layout_alignBottom="@+id/editText1"
    android:layout_alignParentRight="true"
    android:text="Dial"
    android:id="@+id/Dial_button">
    </Button>
</RelativeLayout>


Coding Part:

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);
                       
                  }
            });
       }
}


Explanation for javaCode:

ACTION_DIAL tel:123 -- Display the phone dialer with the given number filled in.

ACTION_VIEW tel:123 -- Display the phone dialer with the given number filled in. Note how the VIEW action does
what what is considered the most reasonable thing for a particular URI.
