最近專案中用到百度地圖，其中一個功能是點選路徑規劃生成的路線的終點圖示彈出InfoWindow,顯示目的地資訊。

我是這樣解決的：

在DrivingRouteOverlay中，

@Override
public final List<OverlayOptions> getOverlayOptions(){

在此方法中新增路線節點、起始點圖示的對應資訊，等到需要點選監聽時，根據根據不同的對應資訊，做相應處理。

}

具體程式碼：

@Override
    public final List<OverlayOptions> getOverlayOptions() {
        if (mRouteLine == null) {
            return null;
        }

        List<OverlayOptions> overlayOptionses = new ArrayList<OverlayOptions>();
        // step node
        if (mRouteLine.getAllStep() != null
                && mRouteLine.getAllStep().size() > 0) {
            
            for (DrivingStep step : mRouteLine.getAllStep()) {
                Bundle b = new Bundle();
                b.putInt("index", mRouteLine.getAllStep().indexOf(step));
                b.putString("end","jiedian");
                if (step.getEntrance() != null) {
                    overlayOptionses.add((new MarkerOptions())
                            .position(step.getEntrance().getLocation())
                                    .anchor(0.5f, 0.5f)
                                            .zIndex(10)
                                                    .rotate((360 - step.getDirection()))
                                                            .extraInfo(b)

                        //點選終點圖示後做相應的操作.
                        mBaiduMap.showInfoWindow(mudiInfoWindow); //顯示氣泡
                    }else{
                       
                    }
