Android SwipeRefreshLayout come implementare canChildScrollUp se child non è un ListView o ScrollView

Question

Ciao ho un SwipeRefreshLayout che contiene un layout relativo che contiene una vista di scorrimento e un'altra vista attualmente quando scorrono verso il basso l'elenco a volte non lo scorrimento di nuovo invece viene eseguito la funzione onRefresh. Come faccio a impedirgli di farlo, a meno che la vista non sia in cima? avevo letto su canChildScrollUp ma non ho trovato un modo per implementarlo correttamente.

heres il mio layout

e heres dove ho implementato la mia classe

swipeLayout = (SwipeRefreshLayout)v.findViewById(R.id.swipe_container); 
     swipeLayout.setColorSchemeColors(Color.parseColor("#ed037c"), Color.parseColor("#c40053"),Color.parseColor("#ffffff"), Color.parseColor("#51af50")); 

     swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { 
      @Override public void onRefresh() { 
       swipeLayout.setRefreshing(true); 
       Log.d("Swipe", "Refreshing Number"); 
       (new Handler()).postDelayed(new Runnable() { 
        @Override public void run() { 

         updateLocalData(); 

        } 
        }, 3000); 
       } 
      }); 

Answer 1

grazie alla @Twibit ho trovato un modo per far funzionare questo il trucco è quello di rilevare la posizione della scrollview se la posizione è 0, per fare in modo che lo SwipeRefreshLayout sia abilitato altrimenti disabilitato.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() { 

      @Override 
      public void onScrollChanged() { 
       int scrollY = scrollView.getScrollY(); 
       if(scrollY == 0) swipeLayout.setEnabled(true); 
       else swipeLayout.setEnabled(false); 

      } 
}); 

Answer 2

Potrebbe essere necessario abilitare/disabilitare il layout colpo se la vista di scorrimento è o non è in cima .

Si può guardare a questo link per l'ispirazione: https://gist.github.com/Frikish/10025057

Un altro esempio che potrebbe aiutare: https://developer.android.com/samples/SwipeRefreshMultipleViews/src/com.example.android.swiperefreshmultipleviews/MultiSwipeRefreshLayout.html

ho avuto un altro problema con scorrimento orizzontale: HorizontalScrollView inside SwipeRefreshLayout

Answer 3

1. Estendere SwipeRefreshLayout e sovrascrivere il metodo canChildScrollUp() che determina se le vostre opinioni possono scorrere verso l'alto.

   //if you have several scrollable views,just iterate 
   for (View view : ...) { 
       if (view != null && view.isShown() && !canViewScrollUp(view)) { 
        // If the view is shown, and can not scroll upwards, return false and start the 
        // gesture. 
        return false; 
       } 
   return true; 
   

2. Scorrere le vostre opinioni e utilizzare il metodo canViewScrollUp() per verificare se qualcuno di loro non si può scorrere verso l'alto

   private static boolean canViewScrollUp(View view) { 
       if (android.os.Build.VERSION.SDK_INT >= 14) { 
        // For ICS and above we can call canScrollVertically() to determine this 
        return ViewCompat.canScrollVertically(view, -1); 
       } else { 
        if (view instanceof AbsListView) { 
        // Pre-ICS we need to manually check the first visible item and the child view's top 
        // value 
        final AbsListView listView = (AbsListView) view; 
        return listView.getChildCount() > 0 && 
         (listView.getFirstVisiblePosition() > 0 
           || listView.getChildAt(0).getTop() < listView.getPaddingTop()); 
       } else { 
        // For all other view types we just check the getScrollY() value 
        return view.getScrollY() > 0; 
       } 
   }
