如何使用屏幕坐标操作Android操作系统

Question

我有屏幕坐标，我想告诉操作系统执行操作，操作系统应该在触摸屏幕坐标时执行操作。就像秘密以某种方式告诉手机该做什么。而用户并不直接与手机互动。如果你知道的话，请告诉我。

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.TextView;

public class MainActivity extends Activity
{
    StringBuilder stringBuilder = new StringBuilder();
    TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.textView = (TextView) findViewById( R.id.strXY );
        this.textView.setText("X: ,Y: ");//texto inicial
        this.textView.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                stringBuilder.setLength(0);
                if (arg1.getAction() == MotionEvent.ACTION_MOVE) {
                    stringBuilder.append("Moving, X:" + arg1.getX() + ", Y:" + arg1.getY());
                } 
                else {
                    stringBuilder.append("Stoped, X:" + arg1.getX() + ", Y:" + arg1.getY());
                }
                textView.setText(stringBuilder.toString());
                return true;
            }
        });
    }
}
