Baidu Maps API MKSearch in the first run, MKSearchListener no return value

API Baidu map

First on the code

public class BusinessActivity extends MapActivity implements OnClickListener {

private SharedPreferences gpsinfo;
private String latitude, longitude, addrStr;
private BMapManager mapManager;

findById ();
setOnClickListener ();
initView ();

/ / Initialize MKSearch
mMKSearch = new MKSearch ();
mMKSearch.init (mapManager, new MySearchListener ());

gpsinfo = getSharedPreferences ("GPS_INFOS", 0);

gpt = new GeoPoint ((int) (Double.valueOf (latitude) * 1e6), (int) (Double.valueOf (longitude) * 1e6));

if (StringUtils.isEmpty (addrStr)) {
/ / Query the latitude and longitude values ​​corresponding to the address location information
mMKSearch.reverseGeocode (gpt);
}
}

public void findById () {
btnFood = findViewById (R.id.food_u);
}

public void setOnClickListener () {
btnFood.setOnClickListener (this);
}

public void initView () {
/ / Initialize MapActivity

The first parameter / / init methods need to fill an application API Key
mapManager.init ("285B415EBAB2A92293E85502150ADA7F03C777C4", null);

/ / Set the map mode to traffic maps

}


public void onClick (View v) {
Intent intent = new Intent ();
switch (v.getId ()) {
case R.id.food_u:
mMKSearch.poiSearchNearBy (ContentUtils.SELECT_FOOD, gpt, 500);
intent.putExtra ("SELECT_CATEGORY", ContentUtils.SELECT_FOOD);
intent.putStringArrayListExtra ("STORE_INFO_LIST", storeList);
intent.setClass (BusinessActivity.this, BusinessResultActivity.class);
break;
default:
break;

}


startActivity (intent);
}

super.onPause ();
}

@ Override

}

/ **

public class MySearchListener implements MKSearchListener {

public void onGetAddrResult (MKAddrInfo result, int arg1) {
if (result == null) {
return;

/ / Position corresponding to the latitude and longitude
addrStr = result.strAddr;

public void onGetPoiDetailSearchResult (int arg0, int arg1) {}

}

public void onGetBusDetailResult (MKBusLineResult arg0, int arg1) {}

public void onGetDrivingRouteResult (MKDrivingRouteResult arg0, int arg1) {}

public void onGetRGCShareUrlResult (String arg0, int arg1) {}

public void onGetTransitRouteResult (MKTransitRouteResult arg0, int arg1) {}

public void onGetWalkingRouteResult (MKWalkingRouteResult arg0, int arg1) {}

Why jump to the first screen poiList is empty, while the second will use the data,
That is why, newcomers seek advice .....
