百度地图自定义多点规划路线
所谓自定义多点规划路线，就是从服务器下载多点的坐标，标注在百度地图上，在按照一定顺序连接规划路线。
（由于本人也是实习小白，所以有做错的，费事麻烦的欢迎大神指出，让我少走点弯路^^）
好戏开始~~（先局部，再整体）
首先数据库文件就省略了，第一是我还没研究明白，第二太多（如果有需要可以找我）
1.这个是spinner，用来选择URL，然后返回到数据库，数据库下载该URL的站点信息。（获取lineName，switch相应的“部分url”，用静态方法返回拼接数据库中URL）
zdlist.add("浦电线");
zdlist.add("华苑线");
zdlist.add("海泰线");
// zdlist.add("福州");
// zdlist.add("厦门");
lineAdapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, zdlist);
lineAdapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
lineSpinner = (Spinner) findViewById(R.id.spinner1);
lineSpinner.setAdapter(lineAdapter);
lineSpinner
.setOnItemSelectedListener(new Spinner.OnItemSelectedListener() {
public void onItemSelected(AdapterView arg0, View arg1,
int arg2, long arg3) {
String lineName = lineSpinner.getSelectedItem()
.toString();
SelectURL.SURL(lineName);
System.out.println("您选择的是：" + lineAdapter.getItem(arg2));
arg0.setVisibility(View.VISIBLE);
}
public void onNothingSelected(AdapterView arg0) {
System.out.println("NONE");
arg0.setVisibility(View.VISIBLE);
}
});
/* 下拉菜单弹出的内容选项触屏事件处理 */
lineSpinner.setOnTouchListener(new Spinner.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
return false;
}
});
/* 下拉菜单弹出的内容选项焦点改变事件处理 */
lineSpinner
.setOnFocusChangeListener(new Spinner.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
}
});
// 地图标注点击处理
bdMap.setOnMarkerClickListener(new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker mMaker) {
// TODO Auto-generated method stub
// 泡泡
List zdu = new ArrayList();
LatLng a = mMaker.getPosition();
String b = "车站";
popupText = new TextView(BusLineSelectActivity.this);
popupText.setBackgroundResource(R.drawable.popup);
popupText.setTextColor(0xFF000000);
popupText.setText(b);
popupText.setGravity(Gravity.CENTER);
bdMap.showInfoWindow(new InfoWindow(popupText, a, 0));
return false;
}
});
bdMap.setOnMapClickListener(new OnMapClickListener() {
@Override
public boolean onMapPoiClick(MapPoi arg0) {
// TODO Auto-generated method stub
return false;
}
@Override
public void onMapClick(LatLng arg0) {
// TODO Auto-generated method stub
bdMap.hideInfoWindow();
}
});
} 3.这个是获取数据库中点的坐标画在地图上，站点嘛，
问题：如果不删除数据库文件，情况1在更换路线时还保留之前的站点，clear地图时还会在画出来，情况2显示不是唯一primary key，求解！！

}
}
};
} drivingOption.passBy(lu);但是我要提几个我认为我代码里的重点。
1)泛型，当你需要将一个泛型中的某一个值，比如说是经度，这时候用到的get和set点对点的赋值。例d1.setLng(d2.getLng)。当你需要像代码中一样，不是点对点，要将精度跟纬度合成这个LatLng ll，这时候应用add这个方法。
2）drivingOption.passBy(lu);lu是List
/**

private void drivingSearch(int index) {
List zdu = new ArrayList();
List lu = new ArrayList();
zdu = bmydb.searchBusList();
int endn = zdu.size() / 2 - 1;
System.out.println(endn);
double lat = zdu.get(0).getLat();
double lng = zdu.get(0).getLng();
LatLng stall = new LatLng(lat, lng);
LatLng endll = new LatLng(zdu.get(endn).getLat(), zdu.get(endn)
.getLng());
for (int i = 0; i < zdu.size() / 2; i++) {
double Latitude = zdu.get(i).getLat();
double Longitude = zdu.get(i).getLng();
LatLng ll = new LatLng(Latitude, Longitude);
PlanNode node = PlanNode.withLocation(ll);
lu.add(node);
}
DrivingRoutePlanOption drivingOption = new DrivingRoutePlanOption();
drivingOption.from(PlanNode.withLocation(stall));
drivingOption.to(PlanNode.withLocation(endll));
drivingOption.passBy(lu);
routePlanSearch.drivingSearch(drivingOption);// 发起驾车路线规划

在最后重申我的这几个小问题
1.当调用BaiduMap.OnMapClickListener这个接口时，点击地图时hideInfoWindow出于某种原因可能不起作用
2.点击Marker返回的经纬度可不可以匹配到list里相应的站点，从而获取其站点名称（list里有这些信息）
3.如果不删除数据库文件，情况1在更换路线时还保留之前的站点，clear地图时还会在画出来，情况2显示不是唯一
的primary key
希望能得到帮助，感谢。
