RecyclerView Tıklanma Olmuyor

Question

RecyclerView Bağdaştırıcım var. Diğer RecyclerView Adaptörlerim de var ve hiçbir sorun olmadan tıklanıyorlar. Ancak, RecyclerView öğelerinden birini tıklattığımda, tost mesajı görünmüyor. Niye ya?

public class AttendanceAdapter extends RecyclerView.Adapter { 
    //... 
    //other overridden factory methods of RecyclerView Adapter and //Constructors and data setting Methods 
    //... 

    public class AttendanceListViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 
     TextView rollNo, name; 
     ImageView isPreset; 

     public AttendanceListViewHolder(View itemView) { 
      super(itemView); 
      itemView.setOnClickListener(this); 

      // ... 
      // Layout Items initialization 
      // ... 
     } 

     @Override 
     public void onClick(View v) { 
      Toast.makeText(mContext,"reyclerViewClicked",Toast.LENGTH_LONG).show(); 
     } 
    } 
} 

DÜZENLEME:

Benim itemView XML şöyle ..

RecyclerView öğe tıklama için yarar sınıf oluşturmak yönteminin altında tarafından uygulanması deneyin. activity veya fragment senin böyle

public class ItemClickSupport { 

    private final RecyclerView mRecyclerView; 

    private OnItemClickListener mOnItemClickListener; 

    private OnItemLongClickListener mOnItemLongClickListener; 

    private View.OnClickListener mOnClickListener = new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if (mOnItemClickListener != null) { 
       RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v); 
       mOnItemClickListener.onItemClicked(mRecyclerView, holder.getAdapterPosition(), v); 
      } 
     } 
    }; 
    private View.OnLongClickListener mOnLongClickListener = new View.OnLongClickListener() { 
     @Override 
     public boolean onLongClick(View v) { 
      if (mOnItemLongClickListener != null) { 
       RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v); 
       return mOnItemLongClickListener.onItemLongClicked(mRecyclerView, holder.getAdapterPosition(), v); 
      } 
      return false; 
     } 
    }; 
    private RecyclerView.OnChildAttachStateChangeListener mAttachListener 
      = new RecyclerView.OnChildAttachStateChangeListener() { 
     @Override 
     public void onChildViewAttachedToWindow(View view) { 
      if (mOnItemClickListener != null) { 
       view.setOnClickListener(mOnClickListener); 
      } 
      if (mOnItemLongClickListener != null) { 
       view.setOnLongClickListener(mOnLongClickListener); 
      } 
     } 

     @Override 
     public void onChildViewDetachedFromWindow(View view) { 

     } 
    }; 

    private ItemClickSupport(RecyclerView recyclerView) { 
     mRecyclerView = recyclerView; 
     mRecyclerView.setTag(R.id.item_click_support, this); 
     mRecyclerView.addOnChildAttachStateChangeListener(mAttachListener); 
    } 

    public static ItemClickSupport addTo(RecyclerView view) { 
     ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support); 
     if (support == null) { 
      support = new ItemClickSupport(view); 
     } 
     return support; 
    } 

    public static ItemClickSupport removeFrom(RecyclerView view) { 
     ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support); 
     if (support != null) { 
      support.detach(view); 
     } 
     return support; 
    } 

    public ItemClickSupport setOnItemClickListener(OnItemClickListener listener) { 
     mOnItemClickListener = listener; 
     return this; 
    } 

    public ItemClickSupport setOnItemLongClickListener(OnItemLongClickListener listener) { 
     mOnItemLongClickListener = listener; 
     return this; 
    } 

    private void detach(RecyclerView view) { 
     view.removeOnChildAttachStateChangeListener(mAttachListener); 
     view.setTag(R.id.item_click_support, null); 
    } 

    public interface OnItemClickListener { 

     void onItemClicked(RecyclerView recyclerView, int position, View v); 
    } 

    public interface OnItemLongClickListener { 

     boolean onItemLongClicked(RecyclerView recyclerView, int position, View v); 
    } 
} 

kullanımı bunu. Bu blog gösterildiği gibi

ItemClickSupport.addTo(mRecyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() { 
    @Override 
    public void onItemClicked(RecyclerView recyclerView, int position, View v) { 
     // your code here 
     Toast.makeText(mContext,"reyclerViewClicked",Toast.LENGTH_LONG).show(); 
    } 
}); 

.

Bir item_view.xml dosyanız olduğunu bildirelim. Ve ana düzeniniz LinearLayout. Bunun için bir kimlik tanımlayın.

public class AttendanceListViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 
    LinearLayout rootView; 
    TextView rollNo, name; 
    ImageView isPreset; 

    public AttendanceListViewHolder(View itemView) { 
     super(itemView); 
     rootView = (LinearLayout)itemView.findViewById(R.id.root_view); 
     rootView.setClickable(true); 
     rootView.setOnClickListener(this); 

     // ... 
     // Layout Items initialization 
     // ... 
    } 

    @Override 
    public void onClick(View v) { 
     Toast.makeText(mContext,"reyclerViewClicked",Toast.LENGTH_LONG).show(); 
    } 
}
