title: Memory issue with items in BaseAdapter
body: <p>I have a <code>ListView</code> where every row view is inflated from this xml layout (by activity layout inflater):</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:baselineAligned="false"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:background="@drawable/topic_list_item_selector"

  android:paddingTop="@dimen/list_item_padding_vertical_big" &gt;
  
  &lt;LinearLayout
      android:id="@+id/topics_list_edit_row_label_color"
      android:layout_width="@dimen/label_rect_edge_size"
      android:layout_height="@dimen/label_rect_edge_size"
      android:orientation="vertical" &gt;
  
      &lt;TextView
          android:id="@+id/topics_list_edit_row_label_text"
          android:layout_width="wrap_content"

      &lt;TextView
          android:id="@+id/topics_list_edit_row_text_title"
          style="@style/DefaultText"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:text="title" /&gt;
  
      &lt;LinearLayout
          android:layout_width="fill_parent"

          &lt;TextView
              android:id="@+id/topics_list_edit_row_text_detail_section"
              style="@style/DetailText"

              android:text="2 sections"
              android:textColor="#818181" /&gt;
  
          &lt;TextView
              android:id="@+id/topics_list_edit_row_text_detail_point"

              android:text="85 points"
              android:textColor="#818181" /&gt;
      &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>When I return this view in my Adapter via <code>getView()</code>, everything works normally.</p>
  
  <p>But when I change some text in <code>TextView</code> via <code>setText()</code> in <code>getView()</code>, my app consumes about 1mb more with every screen rotation:</p>
  
  <pre><code>public class TopicListAdapter extends BaseAdapter{
  ...
  public View getView(int position, View convertView, ViewGroup parent)  {
       View rowView;
  
   if (convertView == null)
       {
       LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
           rowView = inflater.inflate(R.layout.topics_list_edit_row, parent, false);  
           ...
  
           Typeface myTypeface = Typeface.createFromAsset(context.getAssets(), "Roboto-Thin.ttf");     //Added
  
           TextView labelT = (TextView) rowView.findViewById(R.id.topics_list_edit_row_label_text);
       labelT.setTypeface(myTypeface);   //Added
           labelT.setText("A"); //!!!! when I delete this line everything works normally !!!!
           ...
        }
        ...
   }
   }
  </code></pre>
  
  <p>I think maybe my activity context remains alive after every screen rotation but if this is the case then how does it happen and how do I avoid it?</p>
