Android SearchView onclick

Question

I have a searchView which looks like this:

private void setupSearchView() {
    mSearchView = (SearchView) getActivity().findViewById(
            R.id.search_vi         


        

Answer 1

A search widget that intercepts all touches on its children and does a callback on touch down:

class InterceptTouchSearchView(context: Context, attrs: AttributeSet) : SearchView(context, attrs) {

  var onActionDownIntercepted: (() -> (Unit))? = null

  override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
    return true
  }

  @SuppressLint("ClickableViewAccessibility")
  override fun onTouchEvent(ev: MotionEvent?): Boolean {
    if (ev?.action == MotionEvent.ACTION_DOWN) {
      onActionDownIntercepted?.invoke()
    }
    return false
  }
}

Usage: search_view.onActionDownIntercepted = { onSearchFieldClicked() }
