Android is the open source operating system for Linux-based portable deviceswhich is released by Google company.Statistical data show that the Android system isgradually gaining more space and position of the mobile internet field.Increasingandroid mobile application and mobile games demand,encourage mobile phonemanufacturer and application developers to increase the android application developmentefforts, but also generated a lot of third party electronics market.For android developers,the third party electronic market prosperity greatly increase the developers to promotetheir chance of application.With android, as a representative of the open platform witha strong potential of development, will be the first choice of developers.Application framework layer of Android system which uses a layered architecturemodel provides UI controls and powerful function types, and the overall visual effectand experience are also very good.When application developers develop their applications,they can directly call or inheritance UI controls through inheritance or provide the existingUI controls to realize the personalized expanding, spend a little time and energy willbe able to develop glaring application, very simple and convenient.Products are morelikely to attract customers use, at the same time, the Android mobile phone manufacturergenerally will have company with the characteristics of the widget function applied inmobile phone products as a mobile phone embedded in a big selling point. Becausethe existing widget framework support only seven of the most simple UI controls,it isdifficult to develop a good glaring application to attract the attention of mobile phoneusers and meet the needs of users, a large number of applications developers give upin their application to join widget function, leading to the application of the widgetfunction is very few.According to the problems, this subject summarizes the Android widget frameworkof knowledge, and researches the difference of the widget UI controls and the otherUI controls through analysis android source, and then proposes two solutions,finallydesigns a simple widget demo to verify this two solutions is correct feasible.
