如何自動啟用GPS

Question

轉到設置->位置服務->檢查對我的位置的訪問權限，我想以編程方式自動啟用此功能，我在下面的代碼中嘗試了此功能但不起作用

Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE");      
intent.putExtra("enabled", true);
sendBroadcast(intent);
private void turnGPSOn(){     
 String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);      if(!provider.contains("gps")){ 
    //if gps is disabled         
    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);     

          } 
}

考慮API版本//啟用

 Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);

//已禁用

---

Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
sendBroadcast(intent);

在Android清單中設置權限

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
