like this.

button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //do your stuff             
            }
        });

Two ways, either:

  1. Assign an on click event to your button.

    findViewById(R.id.button_id).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

    }
});

    • For this, in your xml file for your button view you'd set:

      android:onClick="onClick"

    • And in your class you'd have your on click method which would look like:

      @Override
public void onClick(View view){
    switch(view.getId()){
        case R.id.button_id:
        // do stuff
        break;
    }
}

  • FYI: First option has problems with casting, second options mixes up two other approaches. If you use the `onClick` attribute, you don't need an `OnClickListener` - just a `public void` method taking a single `View` arg. If you go with the `implements` route, just `setOnClickListener(this)`. – laalto Dec 08 '13 at 08:36
  • oh yea, was late last night ha, the 'OnClickListener' wouldn't be needed. – Joe Birch Dec 08 '13 at 10:26
