AutoCompleteTextView, as the name implies, is a modified TextView that will refer a possible value for the completion of a word or phrase typed into it Such Views are greatly useful in mobile applications when you do not want to devote a large amount of space to a ListView, or you want to speed along the process of entering text into your application To begin creating your Activity for the AutoCompleteTextView, you need to add a new xml file for that layout, a java file for the code, and an Intent Filter to handle the calls

The process of creating these items appeared in the Building the Activities section earlier in the chapter Refer to that section as needed to create the following pieces of the project

Finally, we can add the needed Submit button:

Create a new xml file in your AndroidViews project named autocompletexml Keep in mind that the filename must be all lowercase The file should appear in the layout folder in your Package Explorer Double-click the file to edit it This file is going to control the layout for your AutoCompleteTextView Activity, so you need to have an AutoCompleteTextView in the layout The XML for adding an AutoCompleteTextView looks like this:

Members make, buy, sell, and use specialty parts and accessories to make vehicles more attractive, faster, safer, more fun, and even like new again This organization holds a trade show every year in Las Vegas

You can see what textfieldhtml looks like in Figure 10-6, where the user has entered their name and is clicking the Submit button

You have created a few Views now in xml files, so you should be familiar with the format There is nothing different or unusual about the AutoCompleteTextView You are setting the id to testAutoComplete, and the width and height to fill_parent and wrap_content, respectively You should add the layouts for two Buttons as well These Buttons will be used to control the attributes that you will change Name the Buttons autoCompleteButton and textColorButton, as follows:

Figure 10-6

<Button android:id="@+id/autoCompleteButton" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Change Layout"/> <Button android:id="@+id/textColorButton" android:layout_width="fill_parent"

So what happens when the user clicks the Submit button The text in the text field is sent to the PHP script textfieldphp, but first we need to write that script
