This is my first Android project. It's for convenient currency exchange rate calculation and reference. Please refer to your local bank for actual currency exchange. Bank rates are updated during business hours, Monday to Friday.
1. The main page list allows you to select the currency and quantity you wish to convert. Calculations are based on the bank's "cash selling rate."
2. An "Edit List" option has been added to the upper right corner - after entering, you can long-press and drag up and down to rearrange the order according to the user, or delete items.
Exchange rate retrieval and list refresh have been optimized.
[No need for additional SD card storage, simplified version, small capacity.]
