As mentioned earlier, implementing an AsyncTask is not quite as easy as implementing a Runnable. However, once you get past the generics and varargs, it is not too bad. For example, the following is an implementation of a ListActivity that uses an AsyncTask, from the Threads/Asyncer sample project:

Public Class LostFocusTextBox Inherits System.Web.UI.WebControls.TextBox Protected Overrides Sub AddAttributesToRender( _ ByVal writer As HtmlTextWriter) MyBase.AddAttributesToRender(writer) writer.AddAttribute("onBlur", _ "javascript:alert('You Lost Focus')") End Sub End Class

command= new Customer Review setBook(book)

The resulting HTML for the LostFocusTextBox looks something like this:

Figure 25-12 shows what happens when the text box loses focus. You can extend the usefulness of this control by making the alert message configurable, as shown here:

package com.commonsware.android.async; import import import import import import import android.app.ListActivity; android.os.AsyncTask; android.os.Bundle; android.os.SystemClock; android.widget.ArrayAdapter; android.widget.Toast; java.util.ArrayList;

setCustomer(customer)

Once you start experimenting with altering the TextBox control s HTML, you might wonder whether you could render the entire content of a control by hand, by writing HTML. Once you deal with raw HTML, there s nothing you can t do. You no longer need to find a similar control to inherit from instead, you can generate exactly what you want (although a detailed visual appearance will obviously take a fair bit of work). Rendering a control from scratch is an easy task in ASP.NET all you need to do is inherit from the System.Web.UI.WebControls.WebControl class, which is the base of all ASP .NET web controls. Figure 25-13 shows the inheritance hierarchy for web controls.

Note Technically, you can inherit from the base System.Web.UI.Control class instead, but it provides

fewer features. The main difference with the WebControl class is that it provides a basic set of formatting properties such as Font, BackColor, and ForeColor. These properties are automatically implemented by adding the appropriate HTML attributes to your HTML tag and are also persisted in view state for you automatically. If you inherit from the more basic Control class, you need to provide your own style-based properties, add them as attributes using the HtmlTextWriter, and store the settings in view state so they ll be remembered across postbacks.

To create your own control from scratch, you need to do little more than add the appropriate properties and implement your own custom RenderContents() or Render() method, which writes the HTML output using the HtmlTextWriter class. The RenderContents() method takes place after the Render() method, which means the formatting attributes have already been applied. The code is quite similar to the earlier TextBox examples. It creates a repeater type of control that lists a given line of text multiple times. The RepeatTimes property sets the number of repeats.
