自定義的時間進度條，主要是分一種是黃色，一種是暗灰色，比如某個時間段占用了那么改時間段就是黃色....
首先我們先要準備畫布大小代碼如下：
大家會疑問：progressIndex是多少呢？ 或者又是什么意思呢。這個在之前已經定義了。效果圖可以看出時間段從08：00-20:00（一共12小時） 。如果按5分鐘為一個小單位的話，那么半小時就是6個小單位。一個小時就是12個小單位。那么也就是說progressInde就是12*12.那么每一個單位寬度就是preIndex=mWidth/progressIndex;
第二步就是準備畫筆，畫布，并且在畫筆上畫畫了。在onDraw()方法里面搞事情：
第三步：就是填充色值
最后貼上代碼：
public class MeetingRoomBookView extends View {
/**進度條最大值*/
private float maxCount;
/**進度條當前值*/
private float currentCount;
/**畫筆*/
private Paint mPaint;
private int mWidth,mHeight;
private int preT=6;
//分為24份每一份30分鐘
private long progressIndex=24*preT;
private List<String> timeListIndex=new ArrayList<>();
//每30分鐘有多寬
private long preIndex=0;
private List<MeetingManaBean> bookViewList=new ArrayList<>();
public MeetingRoomBookView(Context context) {
super(context);
}
public MeetingRoomBookView(Context context, AttributeSet attrs) {
super(context, attrs);
setMaxTimeIndex();
}
public MeetingRoomBookView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
//設置時間標誌
private void setMaxTimeIndex(){
timeListIndex.add("8:00");
timeListIndex.add("12:00");
timeListIndex.add("14:00");
timeListIndex.add("18:00");
timeListIndex.add("20:00");
}
/***
* 設置最大的進度值
* @param maxCount
*/
public void setMaxCount(float maxCount) {
this.maxCount = maxCount;
}
/**
* 得到最大進度值
*/
public double getMaxCount(){
return maxCount;
}
/***
* 設置當前的進度值
* @param currentCount
*/
public void setCurrentCount(float currentCount) {
this.currentCount = currentCount > maxCount ? maxCount : currentCount;
