    <p>So, i'm trying to start activity by sweeping across the screen, it works fine for all the other screens, just this screen that doesn't fire the onTouch at all? Would you mind helping me? I've tried debugging it and still have no idea at all. Below are the codes, sorry for not putting snippets only as I thought I might did something wrong elsewhere </p> <p>Btw, I'm also looking for advice on implementing sweeping to change screen. I've read about ViewFlipper and I know it will work very well, but I've around 8 screens with different backend coding needed. Anyways, I really need advice on this.</p> <p>Thanks alot!!</p> <p>Alvin</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; </code></pre> <p></p> <pre><code> &lt;TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="20dip" android:padding="5dip" android:textStyle="bold" android:text="@string/skills" /&gt;

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.

SQuiL has stopped working due to an internal error.

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