    <p>I am writing a app for android 1.5. I want to use a complex listview to display my data. I want to show a ImageView of a drawable object in my List item.</p> <p>I learned from a demo:</p> <pre><code>------&gt; listData.put("Img", listData.put("Img", R.drawable.XXX)); listData.put("Time", "100"); listItems.add(listData); </code></pre> <p>It can display correctly, however, I want to change Img at runtime, The image maybe generated at run-time, so I change the code as follow, but it falls. Can anyone help me ? many thanks!</p> <pre><code>protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.item_list); itemListView = (ListView) findViewById(R.id.listview); ArrayList&lt;HashMap&lt;String, Object&gt;&gt; listItems = new ArrayList&lt;HashMap&lt;String, Object&gt;&gt;(); for(int i = 0;i &lt;XXX.size(); ++i) { HashMap&lt;String, Object&gt; listData = new HashMap&lt;String, Object&gt;(); ---------&gt;/*1)*/ listData.put("Img", new Drawable(XXX)); /*2)*/ listData.put("Time", "100"); /*3)*/ listItems.add(listData); } SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItems, R.layout.listitem, new String[] { "Img", "Time"}, new int[] { R.id.listitem_img, R.id.listitem_time }); itemListView.setAdapter(listItemAdapter); } </code></pre> <p>listitem.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:paddingBottom="4dip" android:paddingLeft="12dip" android:paddingRight="12dip"&gt; &lt;ImageView android:id="@+id/listitem_img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="12dip"/&gt; &lt;TextView android:id="@+id/listitem_time" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textSize="20dip" /&gt; &lt;/LinearLayout&gt; </code></pre>

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.
