    <p>The tvReceiveNumber and tvOnlyOrExceptNumber controls have many rows, so I add a ScrollView control in my UI. I think I can display more rows using ScrollView, but I failed, the ScrollView control don't scroll to diplay more rows. How can I do? Thanks!</p> <p>BTW, if you have better way to display many rows by scrolling screen and keep the toolbar buttons such as btnEdit, btnDeleet and btnClose always display on the bottom of screen, wolud you please tell me?</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/border_ui" &gt; &lt;com.google.ads.AdView android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" ads:adSize="SMART_BANNER" ads:adUnitId="a15284e3e927f18" ads:loadAdOnCreate="false" /&gt; &lt;LinearLayout android:id="@+id/LinearLayoutName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/adView" android:orientation="horizontal" &gt; &lt;TextView android:id="@+id/tvRuleNameTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Rule Name" /&gt; &lt;TextView android:id="@+id/tvRuleName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:text="Rule Name" /&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/LinearLayoutChecked" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/LinearLayoutName" android:orientation="horizontal" &gt; &lt;TextView android:id="@+id/tvEnabledRule" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Enabled Rule" /&gt; &lt;CheckBox android:id="@+id/chEnabledRule" android:layout_width="wrap_content" android:layout_height="wrap_content" android:enabled="false" android:text="" /&gt; &lt;/LinearLayout&gt; &lt;ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@+id/LinearLayoutChecked" &gt; &lt;LinearLayout android:id="@+id/LinearLayoutOption" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/tvReceiveTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Receiver" /&gt; &lt;TextView android:id="@+id/tvReceiveNumber" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1\n2\n3\n4\n5\n6\n7\n8\n9"/&gt; &lt;TextView android:id="@+id/tvOptionTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Forward Option" /&gt; &lt;TextView android:id="@+id/tvOnlyOrExceptNumber" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1\n2\n3\n4\n5\n6\n7\n8\n9\n10" /&gt; &lt;/LinearLayout&gt; &lt;/ScrollView&gt; &lt;LinearLayout android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_gravity="center_vertical" android:background="#DCDCDC" android:gravity="center" android:orientation="horizontal" &gt; &lt;Button android:id="@+id/btnEdit" style="@style/myTextAppearance" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:checked="true" android:text="Edit" /&gt; &lt;Button android:id="@+id/btnDelete" style="@style/myTextAppearance" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:text="Delete" /&gt; &lt;Button android:id="@+id/btnClose" style="@style/myTextAppearance" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:text="Close" /&gt; &lt;/LinearLayout&gt; &lt;/RelativeLayout&gt; </code></pre> <p>The following code is not good too.

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.

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).
