Question

I am trying to make a stop watch application that when you press start it starts and when you press stop it stops. I am using a handler and runnable with post delay, but I want it to only post if the Stop button has not been pressed. This is the way I am talking about implementing what I am talking about.

if(!StopBClicked()){
     handler.postDelayed(r, 1000);
}

This is what I have so far for making it a boolean thing.

public boolean StopBClicked() {
    Button StopB = (Button)findViewById(R.id.StopB);
    StopB.setOnClickListener(new View.OnClickListener(){
        return true;
    }
}

But as you might guess it doesn’t work. It is giving me an error at the “)” after OnClickListener(. I am a little new so I would appreciate a example code. Thank you.

Just run your action when the button is clicked.

Add this to your onCreate:

Button StopB = (Button)findViewById(R.id.StopB);
StopB.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v){
        handler.postDelayed(r, 1000);
    }
}
