    <p>The getView method in my custom ArrayAdapter is getting called multiple times, which I assume it is meant to. Problem is, I have a quantity TextView which is dynamically set but when you scroll and the box goes off screen the value disappears. I am not sure what I am doing wrong and Google is not proving to be much help. Hopefully someone here can help me.</p> <p>The adapater is called:</p> <pre><code>adapter = new MenuAdapter(thisActivity, R.layout.menu, list); setListAdapter(adapter); </code></pre> <p>My Custom ArrayAdapter:</p> <pre><code>public MenuAdapter(Context context, int textViewResourceId, ArrayList&lt;Object&gt; menu) { super(context, textViewResourceId, menu); this.menu = menu; vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; Object cat = menu.get(position); if (cat.getClass().equals(Category.class)) { v = vi.inflate(R.layout.category, null); Category item = (Category)cat; v.setOnClickListener(null); v.setOnLongClickListener(null); v.setLongClickable(false); TextView tt = (TextView) v.findViewById(R.id.category); tt.setText(item.getName()); } else if (cat.getClass().equals(OrderItem.class)) { v = vi.inflate(R.layout.menu, null); OrderItem orderItem = (OrderItem)cat; Item item = orderItem.getItem(); TextView tt = (TextView) v.findViewById(R.id.title); tt.setText(item.getName()); TextView bt = (TextView) v.findViewById(R.id.desc); bt.setText(item.getDescription()); TextView qty = (TextView) v.findViewById(R.id.qty); qty.setId(item.getId()); ImageButton minus = (ImageButton) v.findViewById(R.id.qtyMinus); minus.setTag(item); ImageButton plus = (ImageButton) v.findViewById(R.id.qtyPlus); plus.setTag(item); } return v; } </code></pre> <p>The menu layout:</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="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip" android:background="#FFFFFF"&gt; &lt;RelativeLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent" android:cacheColorHint="#FFFFFF" android:background="#FFFFFF"&gt; &lt;TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center_vertical" android:textSize="16px" android:textColor="#000000" /&gt; &lt;TextView android:id="@+id/desc" android:layout_below="@id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:textSize="11px" android:textStyle="italic" android:textColor="#000000" /&gt; &lt;/RelativeLayout&gt; &lt;ImageButton android:id="@+id/qtyMinus" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/minus" android:paddingTop="15px" android:onClick="minusQty" /&gt; &lt;TextView android:id="@+id/qty" android:layout_width="50px" android:layout_height="50px" android:textColor="#000000" android:textSize="18px" android:gravity="center_vertical|center_horizontal" android:freezesText="true" android:background="@android:drawable/editbox_background"/&gt; &lt;ImageButton android:id="@+id/qtyPlus" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/plus" android:paddingTop="15px" android:onClick="addQty" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>Any help will be greatly appreciated. </p> <p>Many Thanks.</p>

    1. CODo u have 2 types of views? As in you have a Category Item and Order Item? If thats true then you need to change the way u r handling them. Your design needs a little more work.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
