Since I schedule some time in C ++ and C # and now started a work in java
android android studio. I have two small problems that I believe are easy
to solve, the first is that I am getting data from a MySQL database using
PHP, this bank there are 14 entries, my application is getting these 14
entries, but repeating the last all Recycle List View, i.e the last value
passed by JSON is repeated by the amount of select results. The other
problem is that I am trying to use the Parcelable class to send data from a
selected item in the recycle view the other activity, but without success,
I think we have to create an array that stores these values during the Json
as well the position of each item in the list but googled a lot and did not
get success, your help will have great value to me! Below is my code.
Thanks in advance.
