Cevap

<Button 
     android:id="@+id/button2" 
     style="?android:attr/buttonStyleSmall" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_above="@+id/button9" 
     android:layout_alignLeft="@+id/button10" 
     android:layout_marginBottom="20dp" 
     android:onclick="button2click" 
     android:text="Nieuws" /> 

ve bunu bunun gibi yapın java:

public class MainActivity extends Activity { 
    private static Button button_sbm; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


    } 

    public void button2click (View v) 
     { 
      Uri uri = Uri.parse("http://google.com/"); 

      Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
      startActivity(intent); 
     } 
}
