GPS isProviderEnabled总是返回false [英] GPS isProviderEnabled always return false

问题描述

  lm =（LocationManager）this.getSystemService（Context.LOCATION_SERVICE）; 
 boolean isGPS = lm.isProviderEnabled（LocationManager.GPS_PROVIDER）; 
  

，即使启用GPS，它也会返回false。全球定位系统工作正常，但我使用这个布尔值显示弹出没有GPS启用。在这种情况下，每次弹出窗口都会显示出来。

1. 我检查了类似的问题，但它对我没有帮助。 b $ b
2. 是的，我在清单中拥有许可权


3. 我在onResume方法中使用此代码

感谢您的帮助。

解决方案

试试这种方法..

  private void turnGPSOn（）{
 String provider = Settings.Secure.getString（getContentResolver（），Settings.Secure.LOCATION_PROVIDERS_ALLOWED）; 
 if（！provider.contains（gps））{
 final Intent poke = new Intent（）; 
 poke.setClassName（com.android.settings，com.android.settings.widget.SettingsAppWidgetProvider）; 
 poke.addCategory（Intent.CATEGORY_ALTERNATIVE）; 
 poke.setData（Uri.parse（3））; 
 sendBroadcast（poke）; 
} 
} 
  

I've got this code

 lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
 boolean isGPS = lm.isProviderEnabled (LocationManager.GPS_PROVIDER);

and it always return false, even when GPS is enabled. GPS is working correctly but I'm using this boolean value to show pop-up "No GPS enabled". In this situation pop-up is showing up every time

1. I checked similar questions but it doesn't help me.
2. Yes, i have permission in my manifest
3. I'm using this code in onResume method

Thanks for help.

解决方案

try this way..

private void turnGPSOn(){   
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);   
if(!provider.contains("gps")){      
    final Intent poke = new Intent();  
    poke.setClassName("com.android.settings","com.android.settings.widget.SettingsAppWidgetProvider");           
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);   
    poke.setData(Uri.parse("3"));      
    sendBroadcast(poke);  
    } 
}
