如何在模拟器上测试接近传感器？

Question

这是获取proximity传感器的代码。更改传感器时我会显示一条Toast消息。

public class MainActivity extends Activity implements SensorEventListener {

    private SensorManager mSensorManager;
    private Sensor mSensor;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
        mSensorManager.registerListener(this, mSensor,
                SensorManager.SENSOR_DELAY_NORMAL);
    }

    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(this, mSensor,
                SensorManager.SENSOR_DELAY_NORMAL);
    }

    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(this);
    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        Toast.makeText(this, "Sensor Changed", Toast.LENGTH_LONG).show();

        if (event.values[0] == 0) {
            Toast.makeText(this, "Screen off", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "Screen on", Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        // TODO Auto-generated method stub

    }

}

为了测试这个应用程序，我通过 telnet 连接到模拟器，如下所示telnet localhost 5554。我像这样改变接近度sensor set proximity 5。但它不起作用。我做错了什么？

Answer 1

这可以通过以下步骤实现：

1. 打开AS，运行模拟器
2. 点击Extended controls
3. 选择Virtual sensors
4. 在上方选项卡中选择Additional sensors
5. 就这样，你可以随心所欲地玩邻近游戏
