  1. POTablelayout in Scrollview not working
    text
    copied!<p>My fragment loads its data into a tablelayout inside a scrollview. At first, it will load saying "Click on image to view more data".<br> I have a onclick listener from the gallery that should delete all the rows from the tablelayout with <code>tableLayout.removeAllViews();</code>. Then the fragment will add row/rows to a tablelayout inside a scrollview. </p> <p>The tablelayout should change on every click from the gallery.</p> <p>However I am getting: **java.lang.IllegalStateException: ScrollView can host only one direct child. This line shows up with the above error in logcat: <code>getFragmentManager().executePendingTransactions();</code> in my addToTracker function.</p> <p><strong>gallery activity</strong></p> <pre><code>public class GalleryActivity extends Activity { private Gallery[] galleryView;
