使用Java代码的方式实现简易的走势图(1)

这是我第二篇优快云文章了，写这篇文章的时候，心态已经发生了些变化。因为最近看了一个朋友介绍的一本书《奇特的一生》。在很多人看来，书中的主人翁柳比歇夫生活、工作的方法饱受争议。但是，在我看来，如果一个普通人，想要在一生之中有点成就，想要给这个世界留点什么有价值的东西，柳比歇夫的方法或许可以起到很大的作用。当我尝试去按照他的方法去做的时候，我的内心变得很纯净，丝毫不受外界各种琐碎之事的影响。另外看过一本书里面的一句话：当你安静的时候，智慧就会升起来。所以，在很多的时候，我就会去静静的思考，思考多了，慢慢地就看开了一些事情，对时间、生命的本质也会有自己的理解。闲话扯远了，今天我想要给大家带来的是关于纯代码实现的简易的的走势图。下面是效果图:

1.为了减轻我们UI的压力，我们只出了一套图片是针对分辨率为1280 *720，这样为了解决屏幕的适配的问题，我们必须对不同的手机的屏幕的分辨率对图片进行处理。下面是对控件加载显示的核心的类：

                (int) (w * BaseCommond.radio_s),
                (int) (h * BaseCommond.radio_s));
        layoutParams.leftMargin = (int) (left * BaseCommond.radio_s);
        layoutParams.topMargin = (int) (top * BaseCommond.radio_s);
        if (textSize > 0) {
            if (view instanceof TextView) {
                ((TextView) view).setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize * radio_s);
                ((TextView) view).setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));
            }
        }
        container.addView(view, layoutParams);
    }
}

下面我对上面的类的核心的方法进行解读：

/**
     * 初始化屏幕适配的相关参数  从大厅开始
     */
    public static void initScreenParam(Activity act) {
        DisplayMetrics dm = new DisplayMetrics();
        act.getWindowManager().getDefaultDisplay()
                              .getMetrics(dm);
        sW = dm.widthPixels;
        sH = dm.heightPixels;
        Log.d("Base", "sW" + sW + "sH" + sH);
        radioH = sH / H;
        radioW = sW / W;
        if (radioH > radioW) {
            deltaY = (int) ((sH - radioW * H) / 2);
            radio_s = radioW;
        } else {
            deltaX = (int) ((sW - radioH * W) / 2);
            radio_s = radioH;
        }
    }

1.上面的方法获取手机的宽、高像素，然后跟指定为标准的宽、高进行比，求出其比例系数。取宽高比例系数较小的一个，为什么要取系数较小的一个呢？下面我们就来看看下面的图来帮助理解

2.根据图很容易就能够就明白initScreenParam方法计算像素的比例的算法，我们总是取宽或者高的比例中较小的，采取极限的思维，如果去交大的值，那么必然会导致图片的宽或者高溢出屏幕的情况发生，这样图片显示就不完整。
2.这里的第二个核心的方法就是:

 /**
     * 适配控件相关宽高
     *
     * @param container  父容器
     * @param view       控件
     * @param w          控件宽度
     * @param h          控件高度
     * @param leftMargin 以屏幕左上角为原点 的左边距
     * @param topMargin  以屏幕左上角为原点 的上边距
     * @param isRoot     是否为根容器
     */
    public static void setPositionAndWH(ViewGroup container, View view, int w, int h,int leftMargin, int topMargin, Boolean isRoot) {
        FrameLayout.LayoutParams layoutParams;
        layoutParams = new FrameLayout.LayoutParams((int) (w * radio_s),
                (int) (h * radio_s));
        if (isRoot) {
            layoutParams.leftMargin = (int) (leftMargin * radio_s) + deltaX;
            layoutParams.topMargin = (int) (topMargin * radio_s) + deltaY;
        } else {
            layoutParams.leftMargin = (int) (leftMargin * radio_s);
            layoutParams.topMargin = (int) (topMargin * radio_s);
        }
        container.addView(view, layoutParams);
    }

**3.在这里，我们所有的布局都放在FrameLayout里面，所有的空间的位置都是相对于屏幕的左上角进行测量，然后按照比例进行计算其位置以及大小。我们关注的是这个函数的参数的含义，下面简单的介绍一下：
第一个参数是容器，这里就是我们定义的xml的FrameLayout，在我们的Activity的xml中的定义：**

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rl_root"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <FrameLayout
        android:id="@+id/root"
        android:layout_width="match_parent"
        android:layout_height="match_parent"></FrameLayout>
</RelativeLayout>

后面几个参数分别是控件的引用，控件的宽、高、控件离屏幕leftMargin和topMargin，使用的方法如下：

  //彩票的图标的大小和位置的设定
  ImageView ivLottery = new ImageView(this);
  ivLottery.setImageResource(R.drawable.lottery);
  ivLottery.setId(ROOM_LOTTERY);
  ivLottery.setOnClickListener(this);
  BaseCommand.setPositionAndWH(root, ivLottery, 112, 86, 874, 555, false);

4.上述的是用Java代码的方式实现简易的走势图的第一步，即创建在一个控制控件在屏幕上的大小和位置的基础类。
