Get text from pressed button

If you're sure that the OnClickListener instance is applied to a Button, then you could just cast the received view to a Button and get the text:

public void onClick(View view){
Button b = (Button)view;
String text = b.getText().toString();
}

The view you get passed in on onClick() is the Button you are looking for.

public void onClick(View v) {
    // 1) Possibly check for instance of first 
    Button b = (Button)v;
    String buttonText = b.getText().toString();
}

1) If you are using a non-anonymous class as onClickListener, you may want to check for the type of the view before casting it, as it may be something different than a Button.
