[android] Remove an onclick listener

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.

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.

Just reinitializing item as below would do the trick. It would remove onclick,onlonglick,onitemclick,onitemlongclick based on item

mTitleView = findViewById(R.id.mTitleView);

Just put,it has worked for me

itemView.setOnClickListener(null);

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 && li.mOnClickListener != null);
    }

Thank GOD. It checks for null.

So everything is safe. Enjoy :-)

Perhaps setOnClickListener(null) ?

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.

public static void unBingListener(View view) {
    if (view != null) {
        try {
            if (view.hasOnClickListeners()) {
                view.setOnClickListener(null);

            }

            if (view.getOnFocusChangeListener() != null) {
                view.setOnFocusChangeListener(null);

            }

            if (view instanceof ViewGroup && !(view instanceof AdapterView)) {
                ViewGroup viewGroup = (ViewGroup) view;
                int viewGroupChildCount = viewGroup.getChildCount();
                for (int i = 0; i < viewGroupChildCount; i++) {
                    unBingListener(viewGroup.getChildAt(i));
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

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()
