(Facebook) 'dan Okuma metni ErişilebilirlikKullanıcı ile Geri DönüşümKullanıcıHizmetler

Odaklanmamış RecyclerView alt öğelerinin (öğeler) metnini nasıl görebilirim? Erişilebilirlik hizmetimin, anahtar sözcük içeren ekrandan metni okuması gerekiyordu. Bu, özellikle Facebook uygulamasındakiler, RecyclerViews ile uğraştığım durumlar dışında, çoğu durumda iyi çalışır.(Facebook) 'dan Okuma metni ErişilebilirlikKullanıcı ile Geri DönüşümKullanıcıHizmetler

Hem Facebook beslemesi hem de yorumları ekranları RecyclerView'a dayanıyor ve bana erişilebilirlik etkinliklerinden ihtiyacım olan metne erişme olanağı vermiyor gibi görünüyor.

denedim Ne:

public void onAccessibilityEvent(AccessibilityEvent event) { 

    //I've tried looping through event.getText() and it does not contain the text entries 

    //I've also tried the following (with various null checks) 
    AccessibilityRecordCompat record = AccessibilityEventCompat.asRecord(event); 
    AccessibilityNodeInfoCompat source = record.getSource(); 
    List<AccessibilityNodeInfoCompat> nodes = source.findAccessibilityNodeInfosByText("..."); 
    //(and loop through the entries) 

    //I've also tried limiting to the class name "android.support.v7.widget.RecyclerView" 
    //and looking at parcelableData 

    //In the facebook app, the following is always null too 
    source.findFocus(AccessibilityNodeInfoCompat.FOCUS_ACCESSIBILITY); 

}

Hiçbir yerde ihtiyacım olan verileri içeren görünüyor.

Bunun kesinlikle mümkün olup olmadığından emin değilim ya da tamamen yanlış yaklaşıyor olabilirim. TalkBack modunda fark ettim ki, kullanıcı bir RecyclerView çocuğunun münferit elemanlarını okuyamadan önce odaklamalı/odaklamalı, ki bu benim hizmetim için bir seçenek değil (bu ilgi alanlarını bulması gerekiyor)

Bu sorudaki ödülün verilmesi için 23 saatim kaldı. Herhangi bir kimse bile yardımcı olabilecek belirsiz bir fikre sahipse, onu görmeyi çok isterim –

Çözüm konusunda herhangi bir yere ulaştınız mı? – ashishdhiman2007

Ben yapmadım, üzgünüm –

Ben karşılaştım İç içe geçmiş kaydırma görünümleri ile ilgili problem, tüm görüşleri tekrarlı olarak bulmayı çözdüm, sanırım bunu zaten denediniz. İşte çözüm benim durumumda çalışıyor, bunu deneyebilirsiniz de sizin için de işe yarayabilir.

private AccessibilityNodeInfo accessbiltyContent(AccessibilityNodeInfo parentView,String strAddress) throws Exception { 

    int childCount = parentView.getChildCount(); 


    for (int i = 0; i < childCount; ++i) { 
     AccessibilityNodeInfo child = parentView.getChild(i); 
     // child=null; 
     if (child != null) { 

      String strToAddress=strAddress+" > "+child.getClassName().toString(); 
      String nodeText=""; 

      if(child.getText() != null) 
       nodeText=child.getText().toString(); 


      Log.v(TAG,"values =" +child.getClassName().toString(),nodeText,strToAddress)); 
      accessbiltyContent(child,strToAddress); 

     } 
     else { 
      return null; 
     } 
    } 

    return null; 


}

Ebeveynteki tüm görünümleri geçecek ve bulmak için basacaktır.
