百度方式

private void openBaiduMap(double lon, double lat, String title, String describle) {

try {

StringBuilder loc = new StringBuilder();

loc.append("intent://map/direction?origin=latlng:");

loc.append(lat);

loc.append(",");

loc.append(lon);

loc.append("|name:");

loc.append("我的位置");

loc.append("&destination=latlng:");

loc.append(lat);

loc.append(",");

loc.append(lon);

loc.append("|name:");

loc.append(describle);

loc.append("&mode=driving");

loc.append("&referer=Autohome|GasStation#Intent;scheme=bdapp;package=com.baidu.BaiduMap;end");

Intent intent = Intent.getIntent(loc.toString());

if (isInstallPackage("com.baidu.BaiduMap")) {

startActivity(intent); //启动调用

Log.e("GasStation", "百度地图客户端已经安装");

} else {

Log.e("GasStation", "没有安装百度地图客户端");

}

} catch (Exception e) {

e.printStackTrace();

}

}

高德方式

高德-uri-api


private void openGaoDeMap(double lon, double lat, String title, String describle) {

try {

double[] gd_lat_lon = bdToGaoDe(lon, lat);

StringBuilder loc = new StringBuilder();

loc.append("androidamap://viewMap?sourceApplication=XX");

loc.append("&poiname=");

loc.append(describle);

loc.append("&lat=");

loc.append(gd_lat_lon[0]);

loc.append("&lon=");

loc.append(gd_lat_lon[1]);

loc.append("&dev=0");

Intent intent = Intent.getIntent(loc.toString());

startActivity(intent);

} catch (Exception e) {

e.printStackTrace();

}
