所謂自定義多點規劃路線，就是從服務器下載多點的座標，標註在百度地圖上，在按照一定順序連接規劃路線。
（由於本人也是實習小白，所以有做錯的，費事麻煩的歡迎大神指出，讓我少走點彎路^^）
好戲開始~~（先局部，再整體）
首先數據庫文件就省略了，第一是我還沒研究明白，第二太多（如果有需要可以找我）
1.這個是spinner，用來選擇URL，然後返回到數據庫，數據庫下載該URL的站點信息。（獲取lineName，switch相應的“部分url”，用靜態方法返回拼接數據庫中URL）
<span style="white-space:pre"> </span>zdlist.add("浦電線");
zdlist.add("華苑線");
zdlist.add("海泰線");
// zdlist.add("福州");
// zdlist.add("廈門");
lineAdapter = new ArrayAdapter<String>(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("您選擇的是：" + lineAdapter.getItem(arg2));
arg0.setVisibility(View.VISIBLE);
}
public void onNothingSelected(AdapterView<?> arg0) {
System.out.println("NONE");
arg0.setVisibility(View.VISIBLE);
}
});
/* 下拉菜單彈出的內容選項觸屏事件處理 */
lineSpinner.setOnTouchListener(new Spinner.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
return false;
}
});
/* 下拉菜單彈出的內容選項焦點改變事件處理 */
lineSpinner
.setOnFocusChangeListener(new Spinner.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
}
});
// 地圖標註點擊處理
bdMap.setOnMarkerClickListener(new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker mMaker) {
// TODO Auto-generated method stub
// 泡泡
List<ZhanDianUtil> zdu = new ArrayList();
LatLng a = mMaker.getPosition();
String b = "車站";
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.這個是獲取數據庫中點的座標畫在地圖上，站點嘛，
問題：如果不刪除數據庫文件，情況1在更換路線時還保留之前的站點，clear地圖時還會在畫出來，情況2顯示不是唯一primary key，求解！！

}drivingOption.passBy(lu);但是我要提幾個我認爲我代碼裏的重點。
1)泛型，當你需要將一個泛型中的某一個值，比如說是經度，這時候用到的get和set點對點的賦值。例d1.setLng(d2.getLng)。當你需要像代碼中一樣，不是點對點，要將精度跟緯度合成這個LatLng ll，這時候應用add這個方法。
2）drivingOption.passBy(lu);lu是List<PlanNode>的對象而且必須是List對象，list裏就是經過的點。除此之外，必須要起點和終點。OK

在最後重申我的這幾個小問題
1.當調用BaiduMap.OnMapClickListener這個接口時，點擊地圖時hideInfoWindow出於某種原因可能不起作用
2.點擊Marker返回的經緯度可不可以匹配到list裏相應的站點，從而獲取其站點名稱（list裏有這些信息）
3.如果不刪除數據庫文件，情況1在更換路線時還保留之前的站點，clear地圖時還會在畫出來，情況2顯示不是唯一
的primary key
希望能得到幫助，感謝。
