The AutoCompleteTextView is sort of a hybrid between the EditText (field) and the Spinner. With auto-completion, as the user types, the text is treated as a prefix filter, comparing the entered text as a prefix against a list of candidates. Matches are shown in a selection list that, like with Spinner, folds down from the field. The user can either type out an entry (e.g., something not in the list) or choose an entry from the list to be the value of the field. AutoCompleteTextView subclasses EditText, so you can configure all the standard lookand-feel aspects, such as font face and color. In addition, AutoCompleteTextView has a android:completionThreshold property, to indicate the minimum number of characters a user must enter before the list filtering begins. You can give AutoCompleteTextView an adapter containing the list of candidate values via setAdapter(). However, since the user could type something not in the list, AutoCompleteTextView does not support selection listeners. Instead, you can register a TextWatcher, like you can with any EditText, to be notified when the text changes. These events will occur either because of manual typing or from a selection from the drop-down list. The following is a familiar-looking XML layout, this time containing an AutoCompleteTextView (pulled from the Selection/AutoComplete sample application): < xml version="1.0" encoding="utf-8" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/selection" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <AutoCompleteTextView android:id="@+id/edit" android:layout_width="fill_parent" android:layout_height="wrap_content" android:completionThreshold="3"/> </LinearLayout> The corresponding Java code is: public class AutoCompleteDemo extends Activity implements TextWatcher { TextView selection; AutoCompleteTextView edit;

In general, dynamic content should have an expiration time of between 1 and 30 days, depending on the details of your application. An example of doing that declaratively is to place an OutputCache directive at the top of your .aspx page (see dyn-client.aspx): <%@ Page . . . %> <%@ OutputCache Duration="86400" Location="Client" VaryByParam="None" %> That tells the runtime to generate HTTP headers that ask the browser to cache the page for 86,400 seconds (one day). You must include VaryByParam, or the parser will generate an error. A value of None means that multiple versions of the page do not need to be cached independently. The resulting HTTP headers are as follows: Cache-Control: private, max-age=86400 Expires: Tue, 17 Mar 2009 01:34:17 GMT Cache-Control: private prevents proxies from caching the response. ASP.NET also includes an Expires header, even though it s technically redundant.

Once you download and place the three files into the Plugins folder, open SketchUp. From the menu bar in Google SketchUp, select Draw Shapes. You will then be presented with a list of shapes to choose from (Figure 5 8a). When you select a shape from the list, a dialog box will appear asking for the parameters of the model you want to create (Figure 5 8b). Enter them, and click OK.

You can also generate the same headers programmatically, either from code-behind or from an HttpModule. Here s an example (see dyn-client2.aspx): protected void Page_Load(object sender, EventArgs e) { this.Response.Cache.SetExpires(DateTime.Now.AddDays(1.0)); TimeSpan ds = new TimeSpan(1, 0, 0, 0); this.Response.Cache.SetMaxAge(ds); } The call to SetExpires() is optional and can be safely omitted. Cache-Control: private is the default and does not need to be set explicitly. If your content changes more often than once per day, even short client-side expiration times (1 to 10 minutes) can be useful to prevent extra round-trips when users click the Back button in the browser to go back to one of your pages.

String[] items={"lorem", "ipsum", "dolor", "sit", "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel", "ligula", "vitae", "arcu", "aliquet", "mollis", "etiam", "vel", "erat", "placerat", "ante", "porttitor", "sodales", "pellentesque", "augue", "purus"}; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); selection=(TextView)findViewById(R.id.selection); edit=(AutoCompleteTextView)findViewById(R.id.edit); edit.addTextChangedListener(this); edit.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, items)); } public void onTextChanged(CharSequence s, int start, int before, int count) { selection.setText(edit.getText()); } public void beforeTextChanged(CharSequence s, int start, int count, int after) { // needed for interface, but not used } public void afterTextChanged(Editable s) { // needed for interface, but not used } } This time, our activity implements TextWatcher, which means our callbacks are onTextChanged() and beforeTextChanged(). In this case, we are only interested in the former, and we update the selection label to match the AutoCompleteTextView s current contents. Figures 8-6, 8-7, and 8-8 show the application results.

When you re using OutputCache directives, it s also a good idea to use centralized cache profiles to help ensure consistency and to minimize the effort needed to make subsequent changes. The first step is to define a cache profile in your web.config file. Using the previous example, define a profile called Cache1Day:

Figure 5 8. (a.) List of shapes; (b.) enter the dimensions on the shape. Figure 5 9 shows models of the shapes created with the Shapes plug-in.

<system.web> <caching> <outputCacheSettings> <outputCacheProfiles> <add name="Cache1Day" duration="86400" location="Client" varyByParam="none" /> </outputCacheProfiles> </outputCacheSettings> </caching> </system.web> After you define the profile, just reference it from the OutputCache directive (see dyn-client3.aspx): <%@ OutputCache CacheProfile="Cache1Day" %>
