【问题描述】：

从 google i/o 2015 我了解到，google play 服务中有一个新对话框，用户无需退出当前应用程序即可打开位置。下图显示了它的外观：

现在我的问题是，如何在我的项目中实现它？我已经搜索了，但没有找到任何有效的答案，请帮忙！

【问题讨论】：

在 Play Services SDK 中使用 SettingsApi：developer.android.com/reference/com/google/android/gms/location/…

【参考方案1】：

看看google service documetation 的api 你会发现一切都有据可查。 对于您的要求，我建议使用LocationSettingsRequest.Builder 来实现您的目标。

我在 *** 中找到了 Kai 的一个示例：Link

有人专门找SettingsApi页面的，请参考link

【参考方案2】：

使用 Kotlin

通过进行以下更改，此解决方案适用于 Activity 和 Fragment：

关于活动 resolvableApiException.startResolutionForResult(this@MainActivity, REQUEST_CHECK_SETTING)

片段 startIntentSenderForResult(resolvableApiException.resolution.intentSender, REQUEST_CHECK_SETTING, null, 0, 0,0,null)

使用LocationSettingsResponse可以完成这个任务。

在MainActivity.kt内

    private fun checkLocationSetting()
        
            locationRequest = LocationRequest.create()
            locationRequest.apply 
                priority=LocationRequest.PRIORITY_HIGH_ACCURACY
                interval = 5000
                fastestInterval = 2000
            
    
            val builder = LocationSettingsRequest.Builder()
                .addLocationRequest(locationRequest)
            builder.setAlwaysShow(true)
    
            val result: Task<LocationSettingsResponse> = LocationServices.getSettingsClient(applicationContext)
                .checkLocationSettings(builder.build())
    
            result.addOnCompleteListener 
                try
                    val response: LocationSettingsResponse = it.getResult(ApiException::class.java)
                    Toast.makeText(this@MainActivity, "GPS is On", Toast.LENGTH_SHORT).show()
                    Log.d(TAG, "checkSetting: GPS On")
                catch(e:ApiException)
    
                    when(e.statusCode)
                        LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
                            val resolvableApiException = e as ResolvableApiException
// for fragment change below line to: startIntentSenderForResult(resolvableApiException.resolution.intentSender, REQUEST_CHECK_SETTING, null, 0, 0,0,null)
                            resolvableApiException.startResolutionForResult(this@MainActivity, REQUEST_CHECK_SETTING)
                            Log.d(TAG, "checkSetting: RESOLUTION_REQUIRED")
                        
    
                        LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> 
                            // USER DEVICE DOES NOT HAVE LOCATION OPTION
                        
                    
                
            
        

onActivityResult

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) 
        super.onActivityResult(requestCode, resultCode, data)
        when(requestCode)
        
            REQUEST_CHECK_SETTING ->
                when(resultCode)
                    Activity.RESULT_OK->
                        Toast.makeText(this@MainActivity, "GPS is Turned on", Toast.LENGTH_SHORT).show()
                    
                    Activity.RESULT_CANCELED ->
                        Toast.makeText(this@MainActivity, "GPS is Required to use this app", Toast.LENGTH_SHORT).show()
