Possiedo un Recyclerview in NestedScrollview .. tutto funziona correttamente eccetto un thig. Ho tre visualizzazioni totali in NestedScrollview. Le prime due sono LinearLayout e Recyclerview. quando eseguo la mia app l'attività non mostra i due layout principali che inizia dalla parte superiore di Recyclerview.NestedScrollview non parte dall'inizio

Come il suo spettacolo il mio layout:

How its show my layout

Come la sua supponiamo di mostrare:

How its suppose to show

e sto caricando questo layout enite sotto un viewpager e la mia viewpager è un bambino del layout del coordinatore.

it works. Grazie mille :) – Suvro

sì. ha ragione lui. basta aggiungere 'mRecyclerView.setFoucsable (false);'. e la ragione è [qui] (http://stackoverflow.com/a/21235114/1710926) – IndieBoy

grazie per questo. ha impiegato molto tempo a cercare. Ho un layout simile, con un viewpager e un drawerlayout. lo strano problema di scroll si è verificato quando ho aperto il navigationdrawer. ora è tutto risolto :) – ruifn

Ho avuto lo stesso problema, e mi è stato risolto nel modo seguente.

Aggiungi android:descendantFocusability="blocksDescendants" al layout lineare, che è l'unico figlio della visualizzazione di scorrimento nidificata.

Ciò consente alla Vista di scorrimento nidificata di iniziare dall'alto con modifiche minime al codice.

Questa dovrebbe essere la risposta accettata, perché non cambia lo stile delle viste. mentre 'android: focusableInTouchMode =" true "' make appare come se fosse cliccato. – IgniteCoders

Ha funzionato anche per me – ymerdrengene

Basta aggiungere questa linea a figlio di NestedScrollView in xml:

android:focusableInTouchMode="true" 

Il problema va via!

Aggiungi questa linea in

Android layout bambino NestedScrollView s': descendantFocusability = "afterDescendants"
