Question

I have a simple ScrollView in a layout that displays an About Box in a dialog format. So it just pops up on the phone screen in a dialog. The only way for the user to close the box is to click the back button (it is an intent).

Do I have a way of adding a close button to the box or could I have the user hit the box on the screen with their finger and close it?

Here is my xml:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:screenOrientation="portrait"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dip" >

   <TextView
       android:id="@+id/about_box"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="@string/about_text" />
</ScrollView>

That’s what any Android user would want to do. Anyway, if you want to provide the “close with button” functionality just keep in mind this: ScrollView cannot contain more than one item, so you will have to wrap both TextView and Button inside a LinearLayout or something.

But, my suggestion is that you should build an AlertDialog, which can be automatically configured with an “OK” button which will close the dialog.
