i need to know, how to recognize, which button is pressed. Like if i have two buttons ,say button 1 and button2,and both of them performing the same method, say method(),how
OR... you can just put a android:onClick="foo" in the xml code of the button, and define a method on java with the signature. Inside the method foo, get the id and compare it with the one you need
public void foo(View v){
if (v.getId() == R.id.yourButton){
}
else if (v.getId() == R.id.nextButton){
}
}
