If we get CHECK_VOICE_DATA_PASS back, we instantiate a TextToSpeech object. Notice that our MainActivity implements OnInitListener. This allows us to receive a callback when the TTS engine interface has been created and is available, which we receive with the onInit() method. If we get SUCCESS inside of onInit(), then we know we re ready to speak text and we enable our button in the UI. Two more things to note are the call to stop() in onPause(), and the call to shutdown() in onDestroy(). We call stop() because if something goes in front of our application, we ve lost focus and should stop talking. We don t want to interrupt something audio-based in another activity that has jumped in front. We call shutdown() to notify Android that we re through with the TTS engine and the resources can be released. Go ahead and experiment with this example. Try different sentences or phrases. Now give it a large block of text to hear it go on and on. Now consider what would happen if our application were interrupted while the large block of text was being read, perhaps if some other application made a call to the TTS engine with QUEUE_FLUSH, or we simply lost focus. In fact, go ahead and hit the Home button while a large block of text is being

spoken. Because of our call to stop() in onPause(), the speaking stops, even though our application is still running in the background. If our application regains focus, how can we know where we were It would be nice if we had some way to know where we left off so we could begin speaking again, at least close to where we left off. There s a way, but it takes a bit of work.

4, Building User Interfaces and Using Controls This chapter is all about building user interfaces with the Android widget toolkit. We first cover building UIs programmatically, then cover Android s preferred way of defining UIs in XML layout files. We also discuss Android s layout managers and view adapters. Plus, this chapter provides an introduction to the Hierarchy Viewer tool, which you use to optimize UIs.

The TTS engine can invoke a callback in your application when it has completed speaking a piece of text, called an utterance in the TTS world. We set the callback using the setOnUtteranceCompletedListener() method on the TTS instance, mTts in our example above. When calling speak(), we can add a name-value pair to tell the TTS engine to let us know when that utterance is finished being played. By sending unique utterance IDs to the TTS engine, we can keep track of which utterances have been spoken and which have not. If we regain focus after an interruption, we could resume speaking with the next utterance after the last completed utterance. Building upon our previous example, change the code as shown in Listing 15 2 (changes are in bold).

5, Working with Menus and Dialogs Here we extend our discussion on UI programming in Android by talking about menus and dialogs. We show you Android s philosophy on building menus, and then discuss the various types of menus available in the Android SDK. We also talk about dialog components.

The first thing we need to do is make sure our MainActivity also implements the OnUtteranceCompletedListener interface This will allow us to get the callback from the TTS engine when the utterances finish being spoken We also need to modify our button onClick() method to pass the extra information to associate an utterance ID to each piece of text we send For this new version of our example we re going to break up our text into utterances using the comma and period characters as separators We then loop through our utterances passing each with QUEUE_ADD and not QUEUE_FLUSH (we don t want to interrupt ourselves!) and a unique utterance ID, which is a simple incrementing counter, converted to a String, of course We can use any unique text for an utterance ID, since it s a String; we re not limited to numbers.
