Question

我想制作三星设备诊断工具等测试触摸屏应用程序。谁能做到并向我发送源代码？

Answer 1

这个应用程序的开发很容易。你需要明白：

如何获取点击的坐标。

import UIKit
import iAd

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.canDisplayBannerAds = true
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

覆盖方法onDraw，绘制矩形。

最近，我还必须在我的应用中进行此屏幕测试。所以我想出了一个解决方案。我正在使用RectF的数组，即ArrayList<RectF> arr = new ArrayList<>()并按以下顺序绘制此Rects：

左垂直线

private void drawLeftLine(int width, int height) {
int leftPoint = 0;
int topPoint = 0;
int rightPoint = 100;
int bottomPoint = 100;

int maxNoOfRect = height / 100;
int lastRectHeight = height % 100;

for (int i = 0; i < maxNoOfRect; i++) {
    arr.add(new RectF(leftPoint, topPoint, rightPoint, bottomPoint));
    topPoint = bottomPoint;
    bottomPoint = bottomPoint + 100;
}

}

顶部水平线

private void drawTopLine（int w，int h）{

int leftPoint = 0;
int topPoint = 0;
int rightPoint = 100;
int bottomPoint = 100;

int maxNoOfRect = w / 100;
int lastRectWidth = w % 100;

for (int i = 0; i < maxNoOfRect; i++) {
    arr.add(new RectF(leftPoint, topPoint, rightPoint, bottomPoint));
    leftPoint = rightPoint;
    rightPoint = rightPoint + 100;
}
arr.add(new RectF(leftPoint, topPoint, rightPoint + lastRectWidth, bottomPoint));

}

并类似地； 3.右垂直线4.底部水平线，借助于大小为100的RectF的集合。

因此，当用户触摸一个点时，检查该坐标是否位于任何RectF范围内？如果是，请从阵列中删除该RectF。像：

     @Override
public boolean onTouchEvent(MotionEvent event) {
    float touchX = event.getX();
    float touchY = event.getY();

    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            if (mOnViewTouchedListener != null)
                mOnViewTouchedListener.onViewTouched();
            Point point = new Point();
            point.x = (int) event.getX();
            point.y = (int) event.getY();
            Log.d("TAG", "point: " + point);

            for (int i = 0; i < arr.size(); i++) {
                if (arr.get(i).contains(point.x, point.y)) {
                    Log.d("TAG", "Touch IN");
                    arr.remove(i);
                    invalidate();
                    break;
                }
            }
            break;
        case MotionEvent.ACTION_MOVE:
            if (mOnViewTouchedListener != null)
                mOnViewTouchedListener.onViewTouched();
            Log.d("TAG", "ACTION_MOVE");
            Point point1 = new Point();
            point1.x = (int) event.getX();
            point1.y = (int) event.getY();
            Log.d("TAG", "point: " + point1);

            for (int i = 0; i < arr.size(); i++) {
                if (arr.get(i).contains(point1.x, point1.y)) {
                    Log.d("TAG", "Touch IN");
                    arr.remove(i);
                    invalidate();
                    break;
                }
            }
            break;
        default:
            return false;
    }
    return true;
}

因此，这是解决方案。用同样的方式绘制对角线。

从左上角到右下角的对角线：

 private void drawTBDiagonalLine(int w, int h) {

    float height = h;
    float width = w;
    float slope = (height / width);

    float left = 0;
    float top = 0;
    float bottom = 100;
    float right = bottom / slope;

    int maxNoOfRect = h / 100;

    for (int i = 0; i < maxNoOfRect; i++) {
        arr.add(new RectF(left, top, right, bottom));
        left = right;
        top = bottom;
        bottom = bottom + 100;
        right = bottom / slope;
    }
}
