title: Android - ArrayAdapter<LinearLayout> : The specified child already has a parent. You must call removeView() on the child's parent first
body: <p>I'm using an ArrayAdapter with LinearLayout as generic:</p>
  
  <pre><code>public class TestAdapter extends ArrayAdapter&lt;LinearLayout&gt; {
  
  private Context context;
  
  public TestAdapter(Context context) {
      super(context, R.layout.row_result);
      this.context = context;
  }
  
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
  
      View rowView = convertView;
      ViewHolder viewHolder;
  
      // reuse views
      if (rowView == null) {
          LayoutInflater inflater = LayoutInflater.from(context);
          rowView = inflater.inflate(R.layout.row_result, parent, false);
          // configure view holder
          viewHolder = new ViewHolder();
          viewHolder.row = (FrameLayout) rowView.findViewById(R.id.result_row);
          rowView.setTag(viewHolder);
      } else {
          viewHolder = (ViewHolder) convertView.getTag();
      }
      viewHolder.row.removeAllViews();
      viewHolder.row.addView(getItem(position));
      return rowView;
  }
  
  private static class ViewHolder {
      FrameLayout row;
  }}
  </code></pre>
  
  <p>My problem is: The specified child already has a parent. You must call removeView() on the child's parent first.</p>
  
  <p>LinearLayout is a horizontal wrapper for imageView's dinamically created.</p>
  
  <p>This is my error. Seems to be at : viewHolder.row.addView(getItem(position));</p>
  
  <pre><code>java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
