How To Make A Button Unclickable

So right now i am having trouble making the next button unclickable when it is on the last page of the activity. As of right now it goes back to the first screen. How do i make it

Solution 1:

you can set the OnClickListener to null like so

btnNext.setOnClickListener(null);

Solution 2:

I think you just want this method

button.setClickable(false);

Solution 3:

To make a button grey and UnClickable

put android:enabled="false" in button tag

And using code button.setEnabled(false);
