标签： android location location-client

我尝试按照http://developer.android.com/training/location/retrieve-current.html

的指南获取当前位置

我的google play服务已启动，但我的locationclient仍无法连接，并且在运行程序时出现这些错误。 （PS：以前我的位置代码正常，但现在不能，奇怪）

你去吧

package com.example.Wifin;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesClient;
import com.google.android.gms.common.GooglePlayServicesUtil;

import com.google.android.gms.location.LocationListener;
import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.model.LatLng;

import com.google.android.gms.maps.model.MarkerOptions;

import android.app.Activity;
import android.location.Location;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

public class myMap extends Activity implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,LocationListener {

     GoogleMap mMap;
     LatLng Current;
     Marker here;
     LocationClient mLocationClient;
     int resultCode;
     Location mCurrentLocation;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

        resultCode =GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        if(ConnectionResult.SUCCESS == resultCode){
            Log.d("Location Updates",
                    "Google Play services is available.");

        }
        else{
            Toast.makeText(this, "Google Play Service Error " + resultCode,Toast.LENGTH_LONG).show();
        }

        mLocationClient = new LocationClient(this, this, this);

        mCurrentLocation = mLocationClient.getLastLocation();

        Current = new LatLng(mCurrentLocation.getLatitude(),mCurrentLocation.getLongitude());

        mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

        here = mMap.addMarker(new MarkerOptions()
                                .position(Current)
                                .title("you're here!")
                                .snippet("Connect to home2, Signal Strenght -20dBm")
                                .icon(BitmapDescriptorFactory.fromResource(R.drawable.testmarker)));

    }





    @Override
    public void onConnectionFailed(ConnectionResult result) {

    }


    @Override
    public void onConnected(Bundle connectionHint) {
        mLocationClient.connect();
    }


    @Override
    public void onDisconnected() {

    }


    @Override
    public void onLocationChanged(Location arg0) {

    }


}

2 个答案:

答案 0 :(得分：3)

看这里

Not connected. Call connect() and wait for onConnected() to be called.

您应该致电.connect() ..然后在onConnected()中执行该方法。

因为如果它没有连接，而你正试图访问互联网，它就会崩溃。

答案 1 :(得分：0)

我觉得错误的是mLocationClient.connect(); onConnected()方法，因为onConnected()是GooglePlayServicesClient.ConnectionCallbacks接口的方法，当LocationClient被连接时调用onConnected()谷歌服务，这是在调用mLocationclient.connect()方法后发生的。您应该在其他地方使用mLocationClient.connect()方法，例如onResume()或onStart()。
