Question

Title is clear. I\'m having this layout:

_________________
|_______________| <- Toolbar    
|___|___|___|___| <- Tablayout
|               |
|                  


        

Answer 1

I'm actually a Xamarin developer so I can't test if this works in this particular case, but I found an answer which helped me in Xamarin, so I'm gonna share it:

I found a solution that works excellently and can scroll the ListView without problems:

ListView lv = (ListView)findViewById(R.id.myListView);  // your
listview inside scrollview lv.setOnTouchListener(new
ListView.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int action = event.getAction();
        switch (action) {
        case MotionEvent.ACTION_DOWN:
            // Disallow ScrollView to intercept touch events.
            v.getParent().requestDisallowInterceptTouchEvent(true);
            break;

        case MotionEvent.ACTION_UP:
            // Allow ScrollView to intercept touch events.
            v.getParent().requestDisallowInterceptTouchEvent(false);
            break;
        }

        // Handle ListView touch events.
        v.onTouchEvent(event);
        return true;
    }
});

What this does is disable the TouchEvents on the ScrollView and make the ListView intercept them. It is simple and works all the time.

If this won't work, please tell me so I can delete this answer. But maybe it helps anyone since I also found this question and it seems to have no solution.
