does setOnClickListener force button to be clickable?

Question

I have an android ButtonView,

I set it to be unclickable:

 mDoneBtn.setClickable(false);

later I set an onClickListener to it

mDoneBtn.setOnClickListener(new View.OnClickListener() {

does the latter make the button to be clickable again?

Answer 1

First you write:

mDoneBtn.setClickable(false);

Then you set onClick:

mDoneBtn.setOnClickListener(new View.OnClickListener() {...}

The button will trigger onClick event.

But if you set as:

mDoneBtn.setEnabled(false);

and then set your onClick, the onClick event will not be triggered.

Requested Edit:

setClickable automatically becomes true if onClickListenner is implemented. if you do setEnabled(false), until it is set to true, it will not be clickable even if you implement onClickListenner.

Answer 2

From View source:

public void setOnClickListener(OnClickListener l) {
        if (!isClickable()) {
            setClickable(true);
        }
        getListenerInfo().mOnClickListener = l;
}

I guess you can figure out the answer.
