本文提供了一种在Android设备上通过代码开启和关闭GPS的方法，并详细展示了如何使用广播接收器及特定Intent来实现这一功能。此外，还介绍了需要在AndroidManifest.xml中声明的相关权限。

public class GpsManager {

    @SuppressWarnings("deprecation")
    public static void turnGPSOn(Context context) {
        Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
        intent.putExtra("enabled", true);
        context.sendBroadcast(intent);

        String provider = Settings.Secure.getString(context.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"));
            context.sendBroadcast(poke);

        }
    }


    public static void turnGPSOff(Context context) {
        Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
        intent.putExtra("enabled", false);
        context.sendBroadcast(intent);
        // String provider =
        // Settings.Secure.getString(this.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"));
        // this.sendBroadcast(poke);
        // }
    }
}

清单文件添加权限：

 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_GPS" />
    <uses-permission android:name="android.permission.ACCESS_ASSISTED_GPS" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

activity标签下添加：

 android:exported="true"

调用
