  Android is very often used to obtain the screen size. For example, if you want to write a program and make a program with strong versatility, the screen is very applicable. Generally, the layout is defined based on the screen length and width, so

  A few days ago, due to project requirements, another ListView should be placed in one ListView, that is, another ListView should be placed in each ListItem of one ListView. However, at the beginning, we will find that the placed small ListView is

  Suppose: Here I have two activities: A and B. When I transfer data from A to B, I use Bundle to encapsulate the data, and then jump from A to B, when B needs to encapsulate the data and send it back to A, it jumps back to. When receiving data in A,

  Objective: A. java is the main interface and B. java is A sub-function module. The result should be reported to A after B is started and B is finished. First look at the relevant code of A. java     // -- A. java --// /* * Two things are required.
