    <p>I have custom groupViews that need to change state when they are expanded and collapsed. If the same group view is expanded it toggles between two states.</p> <p>The problem i'm having is that the expand method seems to be pulling up some cached version of the views because my updates aren't visible after calling expandGroup.</p> <p>If my listener returns true (handles the whole event itself) without calling expandGroup the update does happen. So something is happening with expandGroup that only allows cached view to be drawn. I have tried invalidating() just about everything. I've tried firing off data update events on the List View. i've tried all this other stuff as well:</p> <pre><code>expandableList.setGroupIndicator(null); expandableList.setAlwaysDrawnWithCacheEnabled(false); expandableList.setWillNotCacheDrawing(true); expandableList.setItemsCanFocus(false); </code></pre> <p>no luck on any of those :(</p> <p>Here's my onClick code:</p> <pre><code>expandableList.setOnGroupClickListener(new OnGroupClickListener() { public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { MusicTrackRow mt = (MusicTrackRow) v; if (mt.isPlaying == true) { mt.setPaused(); } else { mt.setPlaying(); } mt.invalidate(); parent.invalidate(); trackAdapter.notifyDataSetInvalidated(); //need to call expandGroup if the listener returns true.. if returning false expandGroup is //returned automatically expandableList.expandGroup(groupPosition); //no view refresh return true; </code></pre>

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.
