background
In fact, the program ape to develop a demo background, all! A!!! The sample!
Say what for social progress, in order to challenge themselves, all! Is!!! A blind! Pull! Egg!
Is nothing more than a background, the product manager requested this feature!!
Nonsense novel, first GIF for respect!
function
Nothing to say, use the latest version of wechat, open “position” – “send position”, lovely, feel a look, 99.99% similarity is not a dream
Or as usual:
- positioning
- Location data map logo and list display
- Move maps to get the latest location information and display it
- Provides the keyword search function
- One-click send to get specific address information latitude and longitude and so on
- ! @ # $%………………… && (* *)
steps
preparation
Go to amap development Center, register an account, apply for a key, download the JAR package! @ # $%…… & * ()
(By the way, make fun of The documents of Gaode really let people egg! Pain!)
GPS positioning
- Obtain AMapLocation data using Gaud positioning
- Move the map to the location data page using dynamic silky slide display
- Draw the Marker identified by GPS
- Use PoiSearch to retrieve and display the information of nearby landmarks in RecycleView
Moving map Canvas
- Add the OnCameraChangeListener listener to the bound AMap
- After the movement, a wave of Marker pattern animation is performed
- Use GeocodeSearch to encode longitude and latitude inverse addresses into PoiItem text information
- Display the PoiItem in RecycleView
It doesn’t look too hard
code
Direct code, have comments, steady!
