android.support.v4.widget.SwipeRefreshLayout çalışıyor ancak görülebilir değil

Question

İçeriği yenilemek için SwipeRefreshLayout kullanıyorum.

Sorun şu ki çalışıyor, ancak aşağı doğru kaydırırken görünmüyor.

swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipetorefresh); 
     swipeRefreshLayout.setColorSchemeColors(Color.parseColor("#00BCD4"), Color.parseColor("#FF9800"), Color.parseColor("#339a60")); 
     swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { 
      @Override 
      public void onRefresh() { 

       swipeRefreshLayout.setRefreshing(true); 

      } 
     }); 

izin verin:

İşte

o java dosyasında nasıl açıklanmıştır:

     android:layout_margin="@dimen/fab_margin" 
     android:src="@drawable/ic_add_white_24dp"/> 

</android.support.design.widget.CoordinatorLayout> 

İşte content_main.xml dosyanın kod şudur: Burada

ben xml dosyasında SwipeRefreshLayout var nasıl Burada neyin yanlış gittiğini biliyor musunuz?

Üzgünüm, soru çok biçimlendirilmiş gibi görünüyorsa. Ben hala yeni başlıyorum.

skywall tarafından önerildiği gibi, content_main.xmlNestedScrollView içinde sardım ve işe yaradı!

İşte düzenlenmiş content_main.xml var:

senin SwipeRefreshLayout API> 21 sonra setNestedScroll(true)//i'm not really sure about the name hedef eğer daha iyi NestedScrollView veya RecyclerView ile gitmek veya bunu koordinatör düzeni sadece iç içe Düzenleri ile çalışır ayrıca bu bayrağı app:layout_behavior="@string/appbar_scrolling_view_behavior" yerine iç düzenini ve olmalıdır.
