Answer 1

check my answer here Disable Tabs in TabLayout

You can for loop tab and use this function to disable all tab

Answer 2

Based on Michele's Accepted Answer, to disable click for a single tab in Kotlin:

Inside the tabs-containing activity:

val tabs: TabLayout = findViewById(R.id.tabs)
...

(tabs.getChildAt(0) as LinearLayout).getChildAt(desiredTabPositionHere).isClickable = false

---

Inside the fragments (tabs):

(requireActivity().tabs.getChildAt(0) as LinearLayout).getChildAt(desiredTabPositionHere).isClickable = false

---

You can turn the click function on and off (by setting true or false). With the same method, it is also possible to modify visibility, alpha, backgroundColor etc.

Answer 3

It's also possible to avoid child clicks by extending TabLayout class and intercepting all the touch events.

class NonTouchableTabLayout : TabLayout {

    constructor(context: Context) : super(context)
    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

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

If you want to enable clicks again just return false on onInterceptTouchEvent method.

Answer 4

Based on this excellent solution , if someone needs it in Kotlin :

  val tabStrip = mTabLayout.getChildAt(0) as LinearLayout
    for (i in 0..tabStrip.childCount) {
        tabStrip.getChildAt(i).setOnTouchListener(object : View.OnTouchListener{
            override fun onTouch(p0: View?, p1: MotionEvent?): Boolean {
                return true
            }
        })
    }

Or a more elegant solution with lambdas

mTabLayout.setOnTouchListener {v: View, m: MotionEvent ->
        true
 }

A good trick you can use :

create a frame layout that cover the view(s) you want to protect from a click like the following :

<FrameLayout
    android:clickable="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

This code will create and empty/transparent view on top of your view. The android:clickable="true" will intercept the click and prevent the click to go through the view !

This hack can probably be optimized but its few lines of code to protect multiple view at the same time !
