没有调用android – onConnected()来获取位置更新(GooglePlayApi用于位置)

所以我有这个代码：

package com.entu.bocterapp;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.os.Bundle;
import android.widget.Toast;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;

public class LocationManager implements GoogleApiClient.ConnectionCallbacks,GoogleApiClient.OnConnectionFailedListener {

private Context mContext;
private GoogleApiClient mGoogleApiClient;
private Location mLastLocation;
private LocationRequest mLocationRequest;

public LocationManager(Context context) {
    mContext = context;
    //
    if (checkIfGooglePlayServicesAreAvailable()) {
        //Get Access to the google service api
        buildGoogleApiClient();
        mGoogleApiClient.connect();
    } else {
        //Use Android Location Services
        //TODO:
    }
}

public Location getCoarseLocation() {
    if (mLastLocation != null) {
        return mLastLocation;
    } else return null;
}

private synchronized void buildGoogleApiClient() {
    mGoogleApiClient = new GoogleApiClient.Builder(mContext)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
}

private boolean checkIfGooglePlayServicesAreAvailable() {
    int errorCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(mContext);
    if (errorCode != ConnectionResult.SUCCESS) {
        GooglePlayServicesUtil.getErrorDialog(errorCode,(RecentSightings) mContext,0).show();
        return false;
    }
    return true;
}


@Override
public void onConnected(Bundle bundle) {
    Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    if (location != null) {
        mLastLocation = location;
        Toast.makeText(mContext,location.getLongitude() + "," + location.getLatitude() + " : " + location.getAccuracy(),Toast.LENGTH_LONG).show();
    }
}

@Override
public void onConnectionSuspended(int i) {
    Toast.makeText(mContext,"suspended",Toast.LENGTH_LONG).show();
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}

}

我想在这个类中获取位置,但onConnected()永远不会被调用(我等了1-2分钟).我使用调试器,它说谷歌播放服务可用.

有谁知道我做错了什么？我被困在这里几个小时,阅读一切,无法让它工作.

干杯!

解决方法

你必须打电话

mGoogleApiClient.connect();
