Remove an onclick listener

Question

I have an object where the text cycles and displays status messages   When the messages change  I want the click event of the object to change to take you to the activity that the message is relating to   So  I have a TextView mTitleView and I m assigning the event like this   public void setOnTitleClickListener OnClickListener listener        mTitleView setOnClickListener listener       How do I remove that click event   There are some status messages that do not have an actionable area so I d like to turn off the click event   I d also like to be able to cycle through these click events and dispose of them properly  but I m unsure of the best practice

You could add the following extension function  fun View removeClickListener       setOnClickListener null    isClickable   false     And then on your callers you d do  val textView   findViewById R id activity text  textView removeClickListener

Note that if a view is non-clickable  a TextView for example   setting setOnClickListener null  will mean the view is clickable  Use mMyView setClickable false  if you don t want your view to be clickable  For example  if you use a xml drawable for the background  which shows different colours for different states  if your view is still clickable  users can click on it and the different background colour will show  which may look weird

The above answers seem flighty and unreliable   I tried doing this with an ImageView in a simple Relative Layout and it did not disable the onClick event   What did work for me was using setEnabled   ImageView v    ImageView findViewByID R id layoutV   v setEnabled false     You can then check whether the View is enabled with   boolean ImageView isEnabled      Another option is to use setContentDescription String string  and String getContentDescription   to determine the status of a view

Setting setOnClickListener null  is a good idea to remove click listener at runtime    And also someone commented that calling View hasOnClickListeners   after this will return true  NO my friend    Here is the implementation of hasOnClickListeners   taken from android view View class   public boolean hasOnClickListeners             ListenerInfo li   mListenerInfo          return  li    null  amp  amp  li mOnClickListener    null           Thank GOD  It checks for null    So everything is safe  Enjoy  -

mTitleView setOnClickListener null  should do the trick   A better design might be to do a check of the status in the OnClickListener and then determine whether or not the click should do something vs adding and clearing click listeners

Just reinitializing item as below would do the trick  It would remove onclick onlonglick onitemclick onitemlongclick based on item  mTitleView   findViewById R id mTitleView
