我目前正在尝试通过包含单个ImageView的X和Y布局连续更新浮动窗口小部件的位置。从主要活动中，我有：

        new java.util.Timer().schedule(
            new java.util.TimerTask() {
                @RequiresApi(api = Build.VERSION_CODES.N)
                @Override
                public void run() {
                    CursorService.moveCursor(centerX,centerY);

                }
            },1000
    );

上面的代码向（moveCursor）发送信号，该信号试图在CursorService.java包含的浮动叠加层上移动imageview。

centerX和centerY是正确传递的外部变量。

我的问题是试图在CursorService.java类（该类包含整个屏幕上浮动的类似于窗口小部件的覆盖物的类）中实现一个方法。我想每秒更改此光标在覆盖物上的位置，该方法正在调用Mainactivity.java。

以下是CursorService的代码：

import android.app.Service;
import android.content.Intent;
import android.graphics.PixelFormat;
import android.os.Build;
import android.os.IBinder;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.WindowManager;
import android.widget.ImageView;

public class CursorService extends Service {

    private WindowManager mWindowManager;
    private static View mFloatingView;

    private static ImageView cursor;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        //Inflate the floating view layout we created
        mFloatingView = LayoutInflater.from(this).inflate(R.layout.cursor_layout,null);

        int LAYOUT_flaG;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            LAYOUT_flaG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        } else {
            LAYOUT_flaG = WindowManager.LayoutParams.TYPE_PHONE;
        }

        //Add the view to the window.
        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,LAYOUT_flaG,WindowManager.LayoutParams.flaG_NOT_FOCUSABLE,PixelFormat.TRANSLUCENT);

        //Specify the view position
        params.gravity = Gravity.TOP | Gravity.LEFT;        //Initially view will be added to top-left corner
        params.x = 0;
        params.y = 100;

        //Add the view to the window
        mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        mWindowManager.addView(mFloatingView,params);

        cursor = mFloatingView.findViewById(R.id.cursor);
    }

    // Handling the movement
    public static void moveCursor(Integer paramX,Integer paramY) {
/******** Implement changing the x and y position of the cursor here ********/
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        if (mFloatingView != null) mWindowManager.removeView(mFloatingView);
    }
}

我尝试在无限循环中直接更改oncreate方法中的参数，以及从onCreate外部的函数调用中更改X和Y，但是没有运气。对于在浮动叠加层中移动imageview的任何指导，我将不胜感激。

谢谢！
