Android 即使GPS打开，也会显示“位置设置”对话框

以上代码用于请求用户打开位置。但最近我发现，有时它会要求打开位置，即使位置已打开

我最近发现，如果设备已打开电池节电模式或设备位置精度设置较低，则此请求将以相同的状态代码失败。

在

OnFailureListener

中，您可以另外检查GPS是否打开，然后显示用户对话框。大概是这样的：

val request = LocationRequest()
    request.interval = 1000 * 60
    request.fastestInterval = 1000 * 30
    request.smallestDisplacement = 10f
    request.priority = LocationRequest.PRIORITY_HIGH_ACCURACY

    val builder = LocationSettingsRequest.Builder().addLocationRequest(request)
    builder.setAlwaysShow(true)
    val result = LocationServices.getSettingsClient(this).checkLocationSettings(builder.build())
    result.addOnFailureListener {
        if (it is ResolvableApiException) {
            // Location settings are not satisfied, but this can be fixed
            // by showing the user a dialog.
            try {
                // Show the dialog by calling startResolutionForResult(),
                // and check the result in onActivityResult().
                it.startResolutionForResult(this, 1)
            } catch (sendEx: IntentSender.SendIntentException) {
                // Ignore the error.
            }

        }

    }

请记住，您需要在清单文件中添加以下权限

result.addOnFailureListener {
    if (it is ResolvableApiException) {
        try {
           val lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
           val gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);

           if(!gps_enabled) {
               it.startResolutionForResult(this, 1)
           } else {
               powerManager = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
               val locationMode = Settings.Secure.getInt(activityUnderTest.getContentResolver(), Settings.Secure.LOCATION_MODE)

            // location mode status:
            //  0 = LOCATION_MODE_OFF
            //  1 = LOCATION_MODE_SENSORS_ONLY
            //  2 = LOCATION_MODE_BATTERY_SAVING
            //  3 = LOCATION_MODE_HIGH_ACCURACY

               if(powerManager.powerSaverMode) {
                   //show dialog to turn off the battery saver mode
               } else if (locationMode != 3){
                  //show dialog that "make sure your location accuracy is not low"
               }
           }
        } catch (sendEx: Exception) {
            // Ignore the error.
        }

    }

}

如果启用了GPS，我在其他部分应该怎么做？@LalitJadav您可以向toast显示“GPS没有响应，请确保您没有处于电池节省模式”如果用户单击“不感谢”收到相同的响应，我想强制GPS启动。@LalitJadav在这种情况下，您可以关闭应用程序，也许用户此时不想使用GPS还有另一个原因。您只能提示用户，如果GPS没有响应，此应用将无法正常工作。请检查编辑，它只在某些情况下发生，即使用户希望启用并单击“确定”
