Fragment data transmission and Fragment data transmission Fragment is used in development more and more times, and many small projects are directly using Fragment as the carrier of Activity to switch pages. During development, the most important issue of page switching is data transmission. Today, we will focus on the

1. Initial knowledge of fragmentFragment's Chinese meaning is fragmentation, before Android development is, the user interface switches all use activity switching, which causes the entire application to use the slow and very memory, because activity is a heavyweight component, it is inconvenient to use inside the application. So there was a fragment to solve the problem. Fragment is a convenient, lightweigh
