需要在官方文档下载
libs，res，overlay，util
需要接口 RouteSearch.OnRouteSearchListener, GeocodeSearch.OnGeocodeSearchListener
//显示地图
sourceSets{
main{
jniLibs.srcDirs = ['libs']
}
}
这重写的的方法onDriveRouteSearched里
//清除所有地图标识点
aMap.clear();
if (errorCode == AMapException.CODE_AMAP_SUCCESS) {
if (result != null && result.getPaths() != null) {
if (result.getPaths().size() > 0) {
DriveRouteResult mDriveRouteResult = result;
final DrivePath drivePath = mDriveRouteResult.getPaths()
.get(0);
DrivingRouteOverlay drivingRouteOverlay = new DrivingRouteOverlay(
MainActivity.this, aMap, drivePath,
mDriveRouteResult.getStartPos(),
mDriveRouteResult.getTargetPos(), null);
drivingRouteOverlay.setNodeIconVisibility(false);//设置节点marker是否显示
drivingRouteOverlay.setIsColorfulline(true);//是否用颜色展示交通拥堵情况，默认true
drivingRouteOverlay.removeFromMap();
drivingRouteOverlay.addToMap();
drivingRouteOverlay.zoomToSpan();
} else if (result != null && result.getPaths() == null) {
ToastUtil.show(MainActivity.this, R.string.no_result);
}
} else {
ToastUtil.show(MainActivity.this, R.string.no_result);
}
} else {
ToastUtil.showerror(this.getApplicationContext(), errorCode);
}
在重写方法onGeocodeSearched里
GeocodeAddress geocodeAddress = geocodeResult.getGeocodeAddressList().get(0);
//经度
double longitude = geocodeAddress.getLatLonPoint().getLongitude();
//纬度
double latitude = geocodeAddress.getLatLonPoint().getLatitude();
Log.d("MainActivity", longitude + "..." + latitude);
//驾车路线规划
routeSearch = new RouteSearch(MainActivity.this);
routeSearch.setRouteSearchListener(MainActivity.this);
// fromAndTo包含路径规划的起点和终点，drivingMode表示驾车模式
// 第三个参数表示途经点（最多支持16个），第四个参数表示避让区域（最多支持32个），第五个参数表示避让道路
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(new LatLonPoint(40.1767200000, 116.16502000000), new LatLonPoint(latitude, longitude));
RouteSearch.DriveRouteQuery query = new RouteSearch.DriveRouteQuery(fromAndTo, RouteSearch.BUS_DEFAULT, null, null, "");
routeSearch.calculateDriveRouteAsyn(query);
在点击按钮里
//内容地址的坐标查询
GeocodeSearch geocodeSearch = new GeocodeSearch(MainActivity.this);
geocodeSearch.setOnGeocodeSearchListener(MainActivity.this);
//城市编码
GeocodeQuery query = new GeocodeQuery(mEditText.getText().toString(), "010");
geocodeSearch.getFromLocationNameAsyn(query);
