如何在Android中显示位置设置对话框？

Question

我从2015年的Google I/O大会上了解到，Google Play服务中有一个新的对话框，用户不需要退出当前应用程序就可以打开位置。下面的图片显示了它的外观：

现在我的问题是，如何在我的项目中实现这个功能？我已经搜索过了，但没有找到有效的答案，请帮忙！

在Play Services SDK中使用SettingsApi：https://developer.android.com/reference/com/google/android/gms/location/SettingsApi.html - CommonsWare

Answer 1

请查看Google服务文档以获取API的相关信息，文档内容详尽。 对于您的请求，我建议使用LocationSettingsRequest.Builder来实现您的目标。 我在stackoverflow上找到了Kai的示例：链接。

使用 Kotlin

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

对于 Activity resolvableApiException.startResolutionForResult(this@MainActivity, REQUEST_CHECK_SETTING)

对于 Fragment startIntentSenderForResult(resolvableApiException.resolution.intentSender, REQUEST_CHECK_SETTING, null, 0, 0,0,null)

通过使用 LocationSettingsResponse 可以实现此任务。

在 MainActivity.kt 中。

    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()
                    }
                }
            }
        }
    }
