import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		Button bKomunikat1=(Button)findViewById(R.id.buttonKomunikat1);
		Button bKomunikat2=(Button)findViewById(R.id.buttonKomunikat2);
		final Komunikaty kom= new Komunikaty();
		bKomunikat1.setOnClickListener(new View.OnClickListener() {		
			@Override
			public void onClick(View v) {
				kom.wypisz(getApplicationContext());
			}
		});
		
		bKomunikat2.setOnClickListener(new View.OnClickListener() {			
			@Override
			public void onClick(View v) {
				kom.wypisz2(getApplicationContext());
			}
		});
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
}

Klasa – komunikaty:

package com.example.project6_metody;

import android.content.Context;
import android.widget.Toast;

public class Komunikaty {

	public void wypisz(Context akt)
	{
		Toast.makeText(akt, "Komunikat 1", Toast.LENGTH_LONG).show();	
	};
	public void wypisz2(Context akt)
	{
		Toast.makeText(akt, "Komunikat 2", Toast.LENGTH_LONG).show();
	};
}
