How to pass a view's onClick event to its parent on Android?

Questions:

I have a TextView in a layout whos background is a Selector. And the TextView’s text is set to Spanned from HTML.
Then I set the TextView with the LinkMovementMethod.

Now when I tap on the TextView, the click event is not sent to its parent layout to trigger the selector.

How should this be solved?

How to&Answers:

I think you need to use one of those methods in order to be able to intercept the event before it gets sent to the appropriate components:

Activity.dispatchTouchEvent(MotionEvent) – This allows your Activity to intercept all touch events before they are dispatched to the window.

ViewGroup.onInterceptTouchEvent(MotionEvent) – This allows a ViewGroup to watch events as they are dispatched to child Views.

ViewParent.requestDisallowInterceptTouchEvent(boolean) – Call this upon a parent View to indicate that it should not intercept touch events with onInterceptTouchEvent(MotionEvent).

Hope that helps.

Answer:

Declare your TextView not clickable / focusable by using android:clickable="false" and android:focusable="false" or v.setClickable(false) and v.setFocusable(false). The click events should be dispatched to the TextView‘s parent now.

Note:

In order to achieve this, you have to add click to its direct parent. or set
android:clickable="false" and android:focusable="false" to its direct parent to pass listener to further parent.

Answer:

Sometime only this helps:

View child = parent.findViewById(R.id.btnMoreText);
    child.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            View parent = (View) v.getParent();
            parent.performClick();
        }
    });

Another variant, works not always:

child.setOnClickListener(null);

Answer:

Put

android:duplicateParentState="true"

in child then the views get its drawable state (focused, pressed, etc.) from its direct parent rather than from itself.
you can set onclick for parent and it call on child clicked

Answer:

If your TextView create click issues, than remove android:inputType="" from your xml file.

Answer:

This answer is similar to Alexander Ukhov’s answer, except that it uses touch events rather than click events. Those event allow the parent to display the proper pressed states (e.g., ripple effect). This answer is also in Kotlin instead of Java.

view.setOnTouchListener { view, motionEvent ->
    (view.parent as View).onTouchEvent(motionEvent)
}

Answer:

If you want to both OnTouch and OnClick listener to parent and child view both, please use below trick:

  1. User ScrollView as a Parent view and inside that placed your child view inside Relative/LinearLayout.

  2. Make Parent ScrollView android:fillViewport="true" so View not be scrolled.

  3. Then set OnTouch listener to parent and OnClick listener to Child views.
    And enjoy both listener callbacks.
