title: Android RecyclerView addition & removal of items
body: <p>I have a RecyclerView with an TextView text box and a cross button ImageView. I have a button outside of the recyclerview that makes the cross button ImageView visible / gone.</p>
  
  <p>I'm looking to remove an item from the recylerview, when that items cross button ImageView is pressed.</p>
  
  <p>My adapter:</p>
  
  <pre><code>public class MyAdapter extends RecyclerView.Adapter&lt;MyAdapter.ViewHolder&gt; implements View.OnClickListener, View.OnLongClickListener {
  
      private ArrayList&lt;String&gt; mDataset;
      private static Context sContext;
  
      public MyAdapter(Context context, ArrayList&lt;String&gt; myDataset) {
          mDataset = myDataset;
          sContext = context;
      }
  
      @Override
      public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
          View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_text_view, parent, false);
  
          ViewHolder holder = new ViewHolder(v);
          holder.mNameTextView.setOnClickListener(MyAdapter.this);
          holder.mNameTextView.setOnLongClickListener(MyAdapter.this);
  
          holder.mNameTextView.setTag(holder);
  
          return holder;
      }
  
      @Override
      public void onBindViewHolder(ViewHolder holder, int position) {
  
          holder.mNameTextView.setText(mDataset.get(position));
  
      }
  
      @Override
      public int getItemCount() {
          return mDataset.size();
      }
  
  
      @Override
      public void onClick(View view) {
          ViewHolder holder = (ViewHolder) view.getTag();
          if (view.getId() == holder.mNameTextView.getId()) {
              Toast.makeText(sContext, holder.mNameTextView.getText(), Toast.LENGTH_SHORT).show();
          }
      }
  
  
      @Override
      public boolean onLongClick(View view) {
          ViewHolder holder = (ViewHolder) view.getTag();
          if (view.getId() == holder.mNameTextView.getId()) {
              mDataset.remove(holder.getPosition());
  
              notifyDataSetChanged();
  
              Toast.makeText(sContext, "Item " + holder.mNameTextView.getText() + " has been removed from list",
                      Toast.LENGTH_SHORT).show();
          }
          return false;
      }
  
      public static class ViewHolder extends RecyclerView.ViewHolder {
          public TextView mNumberRowTextView;
          public TextView mNameTextView;
  
  
          public ViewHolder(View v) {
              super(v);
  
              mNameTextView = (TextView) v.findViewById(R.id.nameTextView);
          }
      }
  }
  </code></pre>
  
  <p>My layout is:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="horizontal"
      android:gravity="center_vertical"
      android:id="@+id/layout"&gt;
  
      &lt;TextView
          android:id="@+id/nameTextView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textSize="18sp"
          android:padding="5dp"
          android:background="@drawable/greyline"/&gt;
  
      &lt;ImageView
          android:id="@+id/crossButton"
          android:layout_width="16dp"
          android:layout_height="16dp"
          android:visibility="gone"
          android:layout_marginLeft="50dp"
          android:src="@drawable/cross" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>How can I get something like an onClick working for my crossButton ImageView? Is there a better way? Maybe changing the whole item onclick into a remove the item? The recyclerview shows a list of locations that need to be edited. Any technical advice or comments / suggestions on best implementation would be hugely appreciated.</p>
