Summary

We have learned so much in this chapter, and we have explored a plethora of widgets. We learned how to implement widgets in Java code without any XML, and we used our first anonymous classes to handle clicks on a widget and put all our new widget prowess into a working app.

Now, let's move on to look at another way in which we can significantly enhance our UIs.

In the next chapter, we will look at a totally new UI element that we can't simply drag and drop from the palette, but we will still have plenty of help from the Android API. Next up are dialog windows. Additionally, we will also make a start on our most significant app so far, the Note to Self app, for memos, to-do lists, and personal notes.
