Talking AlanlogClock, using Text-To-Speech function.

Extends from previous article; Android AnalogClock and AndroidSpeech: Android can speech! this exercise implement a analog clock with speech function. When you click on the analog clock, the current hour and minute will be speeched.

Create a basic Analog Clock application following the article Android AnalogClock, with the target platform set Android 1.6, because we have to use the Test-To-Speech function.

Add TextView in main.xml, it's helpful for checking.

<?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:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="@string/hello"
  />
<AnalogClock
 android:id="@+id/myAnalogClock"
 android:layout_width="fill_parent"
  android:layout_height="wrap_content"
 />
<TextView
 android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="I can speech"
 />
<TextView
 android:id="@+id/myText"
 android:layout_width="fill_parent"
  android:layout_height="wrap_content"
 />

</LinearLayout>

Implement AnalogClock.OnClickListener to start the speech once the AnalogClick is clicked. In AnalogClock.OnClickListener, the current time can be retrieve by Calendar.getInstance().
