{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et=(EditText)findViewById(R.id.editText1);
call_btn=(Button)findViewById(R.id.button1);
call_btn.setOnClickListener(new OnClickListener()

@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse("tel:"+et.getText().toString()));
startActivity(i);
}
});
}
}
