/** * 根据当前的市，更新区WheelView的信息 */ private void updateAreas() { int pCurrent = mViewCity.getCurrentItem(); mCurrentCityName = mCitisDatasMap.get(mCurrentProviceName)[pCurrent]; String[] areas = mDistrictDatasMap.get(mCurrentCityName); if (areas == null) { areas = new String[] { "" }; } mViewDistrict.setViewAdapter(new ArrayWheelAdapter<String>(this, areas)); mCurrentDistrictName = areas[0];//需要在这里加一行 mViewDistrict.setCurrentItem(0); }
