Just record my own steps:Premise: I started with the Nokia 1202, black and white screen of the function machine;1. Put the card into the Android phone, and use the app Bao to export all the contact man-made vcf suffix file;2.

because Sim the card's contacts are saved in Sim Card of EF files, and each of these files is already fixed. Therefore, there is no way to add a field to save the collected information.Therefore, we can assume that we have the collection of information in the database, if we unplug the card, and then plug in, the collection information will inevitably be discarded (each boot will be re- SIM Card to import contact data), so this feature is meaningless!

Android quick index (City list and contacts) You need to quickly index a city list. Similar to a contact application, the quick indexing function is based on the first letter of the name.To implement this function, you only need to solve two problems: 1. Grouping the list (having the same feature) and quickly locating the first item in the group. 2. Grouping the 'feature' on the right to quickly index the

1. withvaluebackreference Protected void createcontactentry () {arraylist Here withvaluebackreference ("column", "Index"); the first parameter corresponds to the column in the database, and the second parameter represents the value of the return.
