如何建立一个传感器模拟器为Android？ [英] How to Build a Sensor Simulator for Android?

问题描述

我建立针对Android平台的应用程序，我想用加速感应器。现在，我已经找到了一个非常好的应用传感器仿真（ OpenIntents软件SensorSimulator ），但是，对于我想做的事情，一个想创造我自己的传感器模拟器应用程序。

I am building a application for the Android platform and I would like to use the accelerometer. Now, I have found a very nice application for sensor simulation (OpenIntents' SensorSimulator) but, for what I want to do, a would like to create my own sensor simulator application.

我还没有找到的信息（我不知道，如果拆卸模拟器的罐子是正确的），正如我说的，我想建一个传感器模拟器的更小，更简单的版本，更适合我的意图。

I have not found information on how to do this (I do not know if disassembly the jar of the Simulator is correct) and, as I said, I would like to build a smaller and simpler version of a sensor simulator, more suitable for my intents.

你知道我能开始？我在哪里可以看到什么是code的作品，我需要建立？

Do you know where could I start? where can I see what are the pieces of code that I need to build?

基本上，我所有的要求只是对一些方向。

Basically, all my asking just for some direction.

推荐答案

嗯，看来你想那是什么将模拟一个Android设备上的传感器，为您的应用程序，同时测试在模拟器上的应用程序。
也许在你的应用程序，你有这样一行：

Well, it seems what you want to make is a application that will emulate the sensors on a Android device for your application while testing on the emulator.
Probably in your application, you have a line like this:

SensorManager mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);

为什么不创建一个具有您的SensorManager使用的方法的接口：

Why not create a interface that has the methods you use from SensorManager:

interface MySensorManager {
    List<Sensor> getSensorList(int type);

    ... // You will need to add all the methods you use from SensorManager here
}

然后创建一个包装的SensorManager只是调用一个真正的SensorManager对象的方法：

And then create a wrapper for SensorManager that just calls those methods on a real SensorManager object:

class MySensorManagerWrapper implements MySensorManager {
    SensorManager mSensorManager;

    MySensorManagerWrapper(SensorManager sensorManager) {
        super();
        mSensorManager = sensorManager;
    }

    List<Sensor> getSensorList(int type) {
         return mSensorManager.getSensorList(type_;
    }

    ... // All the methods you have in your MySensorManager interface will need to be defined here - just call the mSensorManager object like in getSensorList()
}

和再创造​​另一个MySensorManager，这一次传达了一个插座到桌面的应用程序，您将创建在其中输入传感器的值或东西：

And then create another MySensorManager, that this time communicates over a socket to a desktop application you will create where you enter the sensor values or something:

class MyFakeSensorManager implements MySensorManager {
    Socket mSocket;

    MyFakeSensorManager() throws UnknownHostException, IOException {
        super();
        // Connect to the desktop over a socket
        mSocket =  = new Socket("(IP address of your local machine - localhost won't work, that points to localhost of the emulator)", SOME_PORT_NUMBER);
    }

    List<Sensor> getSensorList(int type) {
        // Use the socket you created earlier to communicate to a desktop app
    }

    ... // Again, add all the methods from MySensorManager
}

最后，更换您的第一行：

And finally, replace your first line:

SensorManager mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);

通过一个新行：

MySensorManager mSensorManager;
if(YOU_WANT_TO_EMULATE_THE_SENSOR_VALUES) {
    mSensorManager = new MyFakeSensorManager();
else {
    mSensorManager = new MySensorManagerWrapper((SensorManager)getSystemService(SENSOR_SERVICE));
}

现在你可以使用你之前使用的的SensorManager中的对象，而不是。

Now you can just use that object instead of the SensorManager you used before.
