在设备所有者应用中启用GPS

本文介绍了在设备所有者应用中启用GPS的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 根据 API文档设备所有者应用可以修改一些安全设置，特别是 LOCATION_MODE 进行以下调用： devicePolicyManager.setSecureSetting（ComponentName admin，字符串设置，字符串值） 由个人资料或设备所有者调用以更新Settings.Secure设置 [...] 设备所有者可以另外更新以下设置： LOCATION_MODE 根据我的理解，LOCATION_MODE的值是一个int（对于loca分别为0 我的问题是字符串值的类型参数。 LOCATION_MODE需要一个int，但是API需要一个字符串。 我错过了什么？ 解决方案 例如，启用gps only位置模式： DevicePolicyManager dpm =（DevicePolicyManager）context.getSystemService（Context.DEVICE_POLICY_SERVICE）; if（dpm.isDeviceOwnerApp（context.getPackageName（）））{ ComponentName componentName = new ComponentName（context，MyDeviceAdmin.class）; dpm.setSecureSetting（componentName，Settings.Secure.LOCATION_MODE，String.valueOf（Settings.Secure.LOCATION_MODE_SENSORS_ONLY））; [感谢@Selvin评论] 它是有道理的，因为当挖掘到javadoc的 LOCATION_MODE ，你可以阅读： 请注意，内部设置值始终以字符串存储[...] According API documentation a device owner app can modify a few "secure settings" and specially the LOCATION_MODE with the following call :devicePolicyManager.setSecureSetting (ComponentName admin, String setting, String value) Called by profile or device owners to update Settings.Secure settings [...] A device owner can additionally update the following settings: LOCATION_MODEAccording my understanding the value of LOCATION_MODE is an int (resp. 0 for location disabled, 1 for GPS only, 2 for battery saving mode and 3 for high accuracy).My problem is the type of the String value parameter. LOCATION_MODE requires an int, but the API requires a String.Did I miss something ? 解决方案 Solution is simply to use the String representation of the int value.For instance to enable "gps only" location mode :DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);if (dpm.isDeviceOwnerApp(context.getPackageName())) { ComponentName componentName = new ComponentName(context, MyDeviceAdmin.class); dpm.setSecureSetting(componentName, Settings.Secure.LOCATION_MODE, String.valueOf(Settings.Secure.LOCATION_MODE_SENSORS_ONLY));}[Thanks to @Selvin comment] It make sense, because when digging into javadoc for LOCATION_MODE, you can read : Note that internally setting values are always stored as strings[...] 这篇关于在设备所有者应用中启用GPS的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
