我有一个包含服务的android应用程序.现在我想在另一个应用程序中访问该服务.我怎样才能做到这一点？我在网上找到了这个应用程序.请找下下面的代码片段

public class LocalWordService extends Service {

    private final IBinder mBinder = new MyBinder();
    private ArrayList<String> list = new ArrayList<String>();

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Random random = new Random();
        if (random.nextBoolean()) {
            list.add("Linux");
        }
        if (random.nextBoolean()) {
            list.add("Android");
        }
        if (random.nextBoolean()) {
            list.add("iPhone");
        }
        if (random.nextBoolean()) {
            list.add("Windows7");
        }
        if (list.size() >= 20) {
            list.remove(0);
        }
        return Service.START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent arg0) {
        return mBinder;
    }

    public class MyBinder extends Binder …

我必须在地图视图上放置标记并在标记上写一个数字.我已经这样做了,但文本对齐方式因不同分辨率而异.下面是参考代码

        float xVal = (float) curScreenCoords.x;  // Point curScreenCoords
        float yVal = (float) curScreenCoords.y-20; // Point curScreenCoords
        Bitmap bitmap = BitmapFactory.decodeResource ( context.getResources() , ( R.drawable.pin_number ) ) ;
        canvas.drawBitmap(bitmap, xVal, yVal, getInnerPaint()); 

        public Paint getInnerPaint() {
         if (innerPaint == null) {
             innerPaint = new Paint();
         }
        innerPaint.setARGB(255, 117, 161, 220); // blue
        innerPaint.setAntiAlias(true);  
        innerPaint.setStyle(Style.FILL);
        return innerPaint;
        }
        canvas.drawText(String.valueOf(10), xVal+20, yVal+22, getCountPaint()); // 10 is just for example, it can vary to one digit to two to three 
        public Paint …
