Under normal circumstances, since the NestedScrollView / ScrollView nested RecyclerView, may cause Recyclerview occupy the entire focus slide leads NestedScrollView / ScrollView content.
The solution to this problem is as follows:
1. Set the root android layout: descendantFocusability = "blocksDescendants";
android: descendantFocusability There are three values:
beforeDescendants: ViewGroup will give priority to acquire control of its subclasses to focus
afterDescendants: viewgroup only get focus if payment is not required to obtain subclass controls focus
blocksDescendants: viewgroup will cover subclass controls and direct access to focus
this methods will result page Editext focus was robbed of lead can not enter, you need to use the second method.
2. For Editext pages need to use the root layout:
android:focusable="true"
android:focusableInTouchMode="true"
3. The first control in NestedScrollView / top ScrollView:
android:focusable="true"
android:focusableInTouchMode="true"
