    <p>I'm attempting to draw to a Canvas inside each element of a ListView. Currently I'm using the following code, which gives a Force Close as soon as I launch the activity:</p> <p><b>Main.java</b></p> <pre><code>public class Main extends Activity { private ListView listView; private List&lt;Row&gt; listRows; public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.year); //Added initialisation from answers listRows = new ArrayList&lt;Row&gt;(); //Add some generic rows to the list for test purposes for (int i=0; i&lt;4; i++) { listRows.add(new Row(this)); } listView = (ListView)findViewById(R.id.ListView1); listView.setAdapter(new RowAdapter(this, listRows)); } } </code></pre> <p><br> <b>RowAdapter.java</b></p> <pre><code>public class RowAdapter extends BaseAdapter { private List&lt;Row&gt; elements; private Context context; public RowAdapter(Context c, List&lt;Row&gt; rows) { this.elements = rows; this.context = c; } @Override public int getCount() { return elements.size(); } @Override public Object getItem(int position) { return elements.get(position); } @Override public long getItemId(int id) { return id; } @Override public View getView(int position, View convertView, ViewGroup parent) { return elements.get(position); } } </code></pre> <p><br> <b>Row.java</b></p> <pre><code>public class Row extends View { public Row(Context context) { super(context); } @Override public void onDraw(Canvas canvas) { //Draw simple string as an example Paint paint = new Paint(); paint.setColor(Color.WHITE); canvas.drawText("Text here...", 0, 0, paint); } } </code></pre> <p>I realise there are probably many problems with my approach to this, so if anyone could point me in the right direction I'd be grateful.</p> <p>Thanks for your help in advance.</p> <p><br> <b>EDIT:</b> The ListView now loads but shows no elements. I'm using the main.xml file shown below.</p> <p><b>main.xml</b></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;ListView android:id="@+id/ListView1" android:layout_width="wrap_content" android:layout_height="wrap_content"&gt; &lt;/ListView&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.
