    <p>I've developed this class to pre-inflate a pool of views and reuse it everytime I need. I've gained seconds in performance while updating UI, which is quite impressive.</p> <p>My Logcat says:</p> <pre><code>updating UI inflating on demand &gt;&gt; 2136mS updating UI reusing from pool &gt;&gt; 937mS </code></pre> <p>Here is my class, just don't mind my clumsy Java coding style, I'm a C++ embedded programmer.</p> <pre><code>import java.util.ArrayList; import java.util.List; import android.view.LayoutInflater; import android.view.View; public class ViewPool { private List&lt;View&gt; mViews; private LayoutInflater mInf; private int mIdx; private int mResource; /** * Constructor, gives Inflater and resource ID to inflate * @param mInf Layout inflater * @param rID Resource ID of view to inflate * @para number number of views that must inflate on first initialization */ public ViewPool(LayoutInflater mInf, int rID, int number) { super(); int idx; mViews = new ArrayList&lt;View&gt;(); this.mInf = mInf; mResource = rID; mIdx=0; // index of first used item for(idx=0; idx&lt;number;++idx) { mViews.add((View)mInf.inflate(mResource, null)); } } /** * Start from first item of pool */ public void Reset() { mIdx=0; } /** * Get a view from pool, if no more views on pool, inflate more * @return */ public View GetView() { View retval; retval = mViews.get(mIdx); ++mIdx; if(mIdx == mViews.size()) // no more views in pool?? mViews.add((View)mInf.inflate(mResource, null)); // inflate more return(retval); } } </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.
