Since it is the configuration of the reference code, then we have to configure the parameters to make the code read, so we have to develop a reading of these parameters of the tool class.Write a well-written success story first. Look at the following code is not very easy to write. If it is simple, the next issue will be updated Oh!1. Configure the param

Daily Development and Application of Android Handler message mechanism and code Testing In many cases, we need to create and maintain a View for each component or all UI threads. For example, to update the display of a TextView We cannot directly create sub-threads in the UI thread. We need to use the message mechanism: handler This blog will show you the Handler we are familiar with, along with an example
