Android位置服务 - 检查位置是否已激活

Question

我正在使用位置服务（使用Google位置服务）在我的应用上实施位置管理器，并且正在寻找一种方法来检查设备系统上的位置是否已激活设置）。我正在像这样连接到位置服务器：

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

private void createLocationRequest() { 
    mLocationRequest = new LocationRequest(); 
    mLocationRequest.setInterval(INTERVAL); 
    mLocationRequest.setFastestInterval(FASTEST_INTERVAL); 
    mLocationRequest.setSmallestDisplacement(SMALLEST_DISPLACEMENT); 
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 
} 

有没有办法检查系统的可用性位置设置？

Answer 1

可能这有助于

LocationManager locateManager=(LocationManager)getSystemService(LOCATION_SERVICE); 
boolean enabled = locateManager.isProviderEnabled(LocationManager.GPS_PROVIDER); 
// check if enabled and if not send user to the GPS settings 
if (!enabled) { 
    Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
    startActivity(intent); 
} // Better solution would be to display a dialog and suggesting to go to the settings
