Question

我正在尝试开发像Doodle Jump这样的游戏。在该游戏中，您将手机移至另一侧，而玩家则移至手机移至的一侧。我使用陀螺仪传感器，因为好像应该这样。我还使用android图形，并在“自定义”视图而不是“活动”中编写所有代码，因为我无法在“活动”中使用图形，因此我只在视图中编写代码并替换“活动”内容

所以基本上我创建了一个名为Gyroscope的类，它可以满足我所需的所有功能：

public class Gyroscope {

public interface Listener{
    void onRotation(float rx, float ry, float rz);
}
private Listener listener;

public void setListener(Listener l){
    listener = l;
}

private SensorManager sensorManager;
private Sensor sensor;
private SensorEventListener sensorEventListener;

Gyroscope(Context context){
    sensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
    sensor = sensorManager.getDefaultSensor(Sensor.TYPE_GYROSCOPE);
    sensorEventListener = new SensorEventListener() {
        @Override
        public void onSensorChanged(SensorEvent sensorEvent) {
            if (listener != null){
                listener.onRotation(sensorEvent.values[0],sensorEvent.values[1],sensorEvent.values[2]);
            }
        }

        @Override
        public void onAccuracyChanged(Sensor sensor, int i) {

        }
    };
}

public void register(){
    sensorManager.registerListener(sensorEventListener,sensor,sensorManager.SENSOR_DELAY_NORMAL);
}

public void unregister(){
    sensorManager.unregisterListener(sensorEventListener);
}

现在要使用此功能，我需要使用“暂停”和“恢复”功能，但它仅适用于活动，而且我不知道如何将其用于视图，因此我将所有类都附加到了项目中，以便您可以更清晰地理解它< / p>

public class  CustomView extends View {
//Screen
Context context;
float screenWidth, screenHeight;

//Player
Sprite spritePlayer;
Bitmap player_Image;

//Floor
Sprite spriteFloor;

//Others
Intent intent;

public CustomView(Context context, int w, int h) { super(context);
    //Screen
    this.context = context;
    screenWidth = w;
    screenHeight = h;

    //Player
    player_Image = BitmapFactory.decodeResource(context.getResources(), R.drawable.player);
    spritePlayer = new Sprite(screenWidth/2-150,screenHeight-900,300,600,player_Image);

    //Floor
    spriteFloor = new Sprite(0,screenHeight-300,screenWidth,200,null);

    //Others
    intent.putExtra("spritePlayer",spritePlayer);
