Android自定义控件之日历控件
三月份学习android，至今也有半年有余，中间也做过两个项目，但是依然感觉自己做的应用不是很有新意，比不上应用市场上那些应用如此绚丽。所以自己仍需继续努力。学习至今，仍感觉自定义控件是一块硬骨头，还没修炼到身后的内功，下面就切入正题，以一次项目的需求，来实现一个自定义的日历控件。效果图先来一发。
我们分析下效果图，然后确定我们的需求。
（1）、绘制星期的自定义View，用于标识日期的礼拜。
（2）、绘制日期的自定义View。
（3）、绘制事务圆圈，从效果图中我们以红圈标识今日有事务。
（4）、绘制选中日期的颜色。
（5）、对选中日期进行点击事件的处理。
通过对效果图的分析，得出了我们的需求，我们在仔细分析效果图，发现里面就是绘制文字和绘制线条，所以我们只要回Canvas的这两个功能即可，主要的难点是如何将这些日期进行位置的安排，接下来我们就来逐个分析如何实现一个自定义View。
实现Week的自定义View
效果图
分析下效果图，我们需要绘制上下两条线、然后绘制描述文字（日、一、二、三、四、五、六）。下面就讲解下我们的实现。先看着部分的源码，然后在分开讲解。

（2）、现在来看看onMeasure方法，我们知道在自定义view中，我们遇到wrap_content属性，这是view的大小可能就不是我们想要的了，所以我们在onMeasure方法中，指定此条件下的大小，即默认大小为300*30。
（3）、onDraw方法，我们在onDraw方法中进行我们需要内容的绘制。我们使用drawLine方法，进行上下横线的绘制，然后int columnWidth = width / 7;计算每列的宽度，为什么计算宽度呢？因为我们要将”日”,”一”,”二”,”三”,”四”,”五”,”六”这七个字放在对应格子的居中位置。通过drawText方法进行绘制文字，我们需要指定绘制文字的起始位置，为了达到居中的位置，我们需要进行计算。

此处不是很了解的，可以参照下爱哥的文章。后面就是一些设置属性，没什么讲头。
至此很简单的实现了我们的week的自定义view。下面我们来分析下日期的实现。
实现日期Date的自定义View
类似WeekView的实现，我们在DateView中的难点也是如何放置这些日期date。先上源码，然后我们在具体分析：

（2）、然后进行重写onMeasure方法，类似于WeekView，不做过多解释，差不多。
（3）、在onDraw方法中进行绘制，绘制的原理，我们根据Calendar获取当前月份的天数，以及第一天是礼拜几，只有计算出礼拜几，我们才知道我们的日历从哪列开始，这样我们就可以计算出每次绘制日期的位置：
<code class="hljs vbscript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span> column = (<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">day</span>+weekNumber - <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>) % <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">7</span>; <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span> row = (<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">day</span>+weekNumber - <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>) / <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">7</span>; daysString[row][column]=<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">day</span> + <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>; <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span> startX = (<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span>) (mColumnSize * column + (mColumnSize - mPaint.measureText(dayString))/<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2</span>); <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span> startY = (<span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">int</span>) (mRowSize * row + mRowSize/<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2</span> - (mPaint.ascent() + mPaint.descent())/<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2</span>);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>
一个礼拜有七天，我们根据日期号和起始计算出日期的对应行列，然后在乘以行列宽，就可以计算出每个日期号的其实位置。这样我们就可以通过drawText进行日期的绘制。我们有一个成员变量记录选中的日期号，然后进行绘制选中的背景色，如下代码：
<code class="hljs mel has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span>(dayString.equals(mSelDay+<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">""</span>)){ <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//绘制背景色矩形</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span> startRecX = mColumnSize * column; <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span> startRecY = mRowSize * row; <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span> endRecX = startRecX + mColumnSize; <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span> endRecY = startRecY + mRowSize; mPaint.setColor(mSelectBGColor); <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">canvas</span>.drawRect(startRecX, startRecY, endRecX, endRecY, mPaint); <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//记录第几行，即第几周</span> weekRow = row + <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>; }</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li></ul>（4）、我们还有一个需求，就是绘制事务标志，我们定义了List daysHasThingList的list对象，这个对象我们用来’装’事务的日期号。然后我们在onDraw方法中判断日期是否包含在这个list中，然后绘制对应的圆圈。

最后就是我们使用自定义View进行显示。如：
