Android show alert window with button

I am learn about android programming in my free time. I am planned to create a simple alert window with a button. We can use AlertDialog class to create android alert window in Android. The sample output using this class as like picture below.

I have created a simple function how to create Android alert window using AlertDialog class. Please check this subroutine :

private void showAlertOk(String strtitle, String strtext, String strbutton)
{
	AlertDialog.Builder builder = new AlertDialog.Builder(formQuestions.this);
	builder.setTitle(strtitle);
	builder.setMessage(strtext);
	builder.setPositiveButton(strbutton, new DialogInterface.OnClickListener()
	{
		public void onClick(DialogInterface dialog, int which)
		{
			//add our code in here
		}
	});
	builder.show();
}

private void showAlertOk(String strtitle, String strtext, String strbutton)

{

AlertDialog.Builder builder = new AlertDialog.Builder(formQuestions.this);

builder.setTitle(strtitle);

builder.setMessage(strtext);

builder.setPositiveButton(strbutton, new DialogInterface.OnClickListener()

{

public void onClick(DialogInterface dialog, int which)

{

//add our code in here

}

});

builder.show();

}

We can give parameter to this Android alert window subroutine to give same result like picture above using command :

showAlertOk("Information", "Please select the right answer", "Close")

1	showAlertOk("Information", "Please select the right answer", "Close")

I hope this simple subroutine can give you more explaining about how to create alert window in Android.
