更新工作--如何在android中通过在触摸屏上滑动手指来测试智能手机屏幕？

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity implements View.OnTouchListener {
    private float startX;
    private float startY;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        View view = findViewById(R.id.touch_view);
        view.setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                startX = event.getX();
                startY = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                float endX = event.getX();
                float endY = event.getY();
                float distanceX = endX - startX;
                float distanceY = endY - startY;

                // 在这里可以根据滑动的距离进行相应的测试操作

                startX = endX;
                startY = endY;
                break;
            case MotionEvent.ACTION_UP:
                // 在这里可以进行滑动结束后的测试操作
                break;
        }
        return true;
    }
}
