打开GPS

1.第一种方法

private void toggleGPS() {
             Intent gpsIntent = new Intent();
             gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
             gpsIntent.addCategory("android.intent.category.ALTERNATIVE");
             gpsIntent.setData(Uri.parse("custom:3"));
             try {
                     PendingIntent.getBroadcast(StartActivity.this, 0, gpsIntent, 0).send();
             } catch (CanceledException e) {
                     e.printStackTrace();
             }
     }
  

2.第二种方法
   private void openGPSSettings() {       
       //获取GPS现在的状态（打开或是关闭状态）
    boolean gpsEnabled = Settings.Secure.isLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER );
  
     if(gpsEnabled)
     {

    //关闭GPS
      Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, false );
     }
     else
     {
      //打开GPS  www.2cto.com
      Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, true);

    }
    
  3.第三种方法（手动设置）

     LocationManager alm = (LocationManager)StartActivity.this.getSystemService(Context.LOCATION_SERVICE);       
        if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER))
        {           
         Toast.makeText(this, "GPS模块正常", Toast.LENGTH_SHORT).show();
        }       
       
        Toast.makeText(this, "请开启GPS！", Toast.LENGTH_SHORT).show();
        Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);
        startActivityForResult(intent,0); //此为设置完成后返回到获取界面
