Question

I use onLongClick and onClick events of a button to get user inputs. Whenever; the user long click and triggers onLongClick event, the onClick event is also triggered. I couldn’t find my problem. The code of two methods are shown in below:

@Override
    public void onClick(View v) {
        switch(((Button) v).getId())
        {
        case R.id.enter:
            EntertheNumber();
            break;
        case R.id.clear:
            CleartheNumber();
            break;
        case R.id.number_zero:
        case R.id.number_one:
        case R.id.number_two:
        case R.id.number_three:
        case R.id.number_four:
        case R.id.number_five:
        case R.id.number_six:
        case R.id.number_seven:
        case R.id.number_eight:
        case R.id.number_nine:
            AddtotheNumber(mEditor, (Button) v);
            break;
        }
@Override
    public boolean onLongClick(View view) {
        if(SMBGuesstheNumber.bDisplayFlagList)
        {
            theActiveButton = (Button) view;
            showDialog(R.id.display_flaglist);
        }
        return false;
    }

Actually, my project is Open Source. So, you can find all the code at http://code.google.com/p/guessthenumber/

Thank you.

I’m not sure what order these events occur but the onLongClick handler returns a bool to indicate whether the event was handled. You should return true if you handled it so that other click events will not be called. I don’t know if this will prevent prevent the onClick() from firing though.

You may also turn these events off and on using setClickable(boolean) and setLongClickable(boolean)
