Summary of an android alarm on the Internet

A week ago, I decided to write a self-developed Android appProgramSince I was engaged in development, most of the time I spent in my work has been wasted in vain. My elder sister told me a lot about development, so I decided to resign and leave, the boss does not know how to train new people, but does not understand that learning should be done step by step. What makes my elder sister feel best is that my ability does not pose any threat to her role, if you do not learn the basics well, you can start a very difficult project. If you are a person with no Japanese knowledge, you can't learn Japanese every day!

Learning should start with the basics. With this idea, I started my android alarm clock project, which uses a lot of tips .,

1. Database --- used to save the alarm time set by the user.

2. boradcast is used to send broadcasts and make an alarm.

3. View component listview preferences custom components, such as timepickpreference, seekbarpreference, and mutilistviewpreference

4. Continue tomorrow
