Baidu Map API Usage Series 2-Show Map

This blog introduces basic maps using the types of maps inside, displaying real-time traffic maps, and displaying a marker on the map.

Note here that the operation of the map does not have to show the map of the control directly to complete, Baidu added a property for him Baidumap can interpret this attribute as a map manager

We can get this property by the corresponding Get method

Baidumapbaidumapview. Getmap ();

Map type

Baidu Maps provides two types of map resources (normal vector maps and satellite maps)

Baidumap .   normal vector map

Baidumap .   Satellite map

Baidumap . Setmaptype (map_type);

/**  set the type of map to display  Map Type */

private voidSetdisplaymaptype (intCurrentmaptype) { Switch(currentmaptype) {Case    map_normal :         // Show map types are divided into two categories 1. General vector maps 2. Satellite mapBaidumap. Setmaptype (Baidumap.Map_type_normal);  Break; Case    map_satellite :        Baidumap. Setmaptype (Baidumap.Map_type_satellite);  Break; default:        Baidumap. Setmaptype (Baidumap.Map_type_normal);  Break;}

Show real-time traffic maps

Baidu has now supported traffic maps for multiple cities

Baidumap. settrafficenabled (Boolean);

 /** * Set display implementation traffic map * @param isChecked  display true show false do not show */private voidsetdisplaytraffic (BooleanisChecked) {    if(isChecked) { // show real-time traffic map Baidumap. settrafficenabled (true); }Else{        Baidumap. settrafficenabled (false); }}

Show a marker on the map

 /** * display labels on the map by latitude * @param longitude  Longitude * @param latitude /c8> Latitude * /private voidSETLATLNG (DoubleLongitude,Doublelatitude) {     // build the coordinates of the callout through latitude/longitude //This place needs to be aware that when instantiating a latlng class, it is latitude longitude when passing parameters.latlng point =Newlatlng (latitude, longitude); Bitmap Bitmap = bitmapfactory.Decoderesource(Getresources (), r.drawable.Ic_launcher);  // building display icons for labels with bitmap bitmapdescriptor bitmapdescriptor = bitmapdescriptorfactory. Frombitmap    (bitmap);  // Create a overlay //Set the coordinates of the callout position//Set the icon for the label icons//Set the title of the label title//Set the label to drag DRA Ggable true can be dragged and false can not drag long press function can listen to drag eventsoverlayoptions options =Newmarkeroptions (). Position (point). Icon (bitmapdescriptor). Title ( " Hao King building" ). Draggable (true); Baidumap. Setonmarkerdraglistener ( This);  // add overlay with map above //This method has a return value of OverlayMarker= (Marker)Baidumap. Addoverlay (options);  // Show Default overlay location Displaymarker ( " default" , Marker);}

remove removes from the map.
