Slider inside ExpandableListView disables getChildView

I have place SliderLayout inside ExpandableListView. On tapping slider it should expand and show child listview but it never happens.
I have set

mDemoSlider.setFocusable(false);

Adding image as follows

```
DefaultSliderView textSliderView = new DefaultSliderView(context);
// initialize a SliderLayout
textSliderView
.image(locationListItem.getLocationImageUrl())
.setScaleType(BaseSliderView.ScaleType.CenterCrop);
mDemoSlider.addSlider(textSliderView);
```

Kindly, help in it thanks.
