Android gps 以编程方式打开和关闭

Android gps programmatically turning on and turning off(Android gps 以编程方式打开和关闭)

问题描述

我编写了一个简单的 gps 代码，它在某些设备(比如 moto g)中以编程方式打开和关闭 gps，但在某些旧版本或三星二重奏和其他一些设备上它没有以编程方式打开 gps.请帮我解决这个问题，

i have written a simple gps code , which is turning on and turning off the gps programmatically in some device(say moto g) but some older version or Samsung duos and some other devices it not turning on gps programmatically . please help me regarding this issue,

如果gps开启成功我会得到纬度和经度，所以我会用它

If gps is turned on successfully i will get latitude and longitude, so i will use it

提前致谢

您必须从清单文件中降低您的 API 级别

You have to decrease your API level from Manifest File

推荐答案

请根据您的要求更改.

GPS 转向

    private void turnGPSOn() 
{

    String provider = android.provider.Settings.Secure.getString(getContentResolver(),android.provider.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);
    }
}

停止 GPS 并获得更长的纬度

Stop GPS and Get Lat Long

此代码用于停止 gps

this code for stop gps

LocationUtil locationUtil = new LocationUtil(getApplicationContext());
                        locationUtil.stopUsingGPS();
 if (statusOfGPS) {

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

     String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
     if(provider.contains("gps"))
     { //if gps is enabled
         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);
     }
