Android自定義View實(shí)現(xiàn)課程表表格
更新時(shí)間：2019年03月26日 15:18:33 作者：Chaek
這篇文章主要為大家詳細(xì)介紹了Android自定義View實(shí)現(xiàn)課程表表格，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
自己閑下來時(shí)間寫的一個(gè)課表控件，使用的自定義LinearLayout，里面View都是用代碼實(shí)現(xiàn)的，最終效果如下圖，寫的可能有問題希望多多指點(diǎn)
創(chuàng)建一個(gè)自定義LinearLayout 控件用來裝載課程的信息和課程的周數(shù)，和節(jié)數(shù)大概的布局三這樣的
根據(jù)上面的看來覺得總體布局我分了兩個(gè) 上面的星期是一個(gè) 下面的節(jié)數(shù)和格子是一個(gè) 總體使用Vertical 而單獨(dú)內(nèi)部者使用了Horizontal布局 中間使用了兩種布局線條 是這樣的
/**
* 橫的分界線
*
* @return
*/
private View getWeekTransverseLine() {
TextView mWeekline = new TextView(getContext());
mWeekline.setBackgroundColor(getResources().getColor(R.color.view_line));
mWeekline.setHeight(TimeTableLineHeight);
mWeekline.setWidth(LayoutParams.FILL_PARENT);
return mWeekline;
}
/**
* 豎向分界線
*
* @return
*/
private View getWeekVerticalLine() {
TextView mWeekline = new TextView(getContext());
mWeekline.setBackgroundColor(getResources().getColor(R.color.view_line));
mWeekline.setHeight(dip2px(TimeTableWeekNameHeight));
mWeekline.setWidth((TimeTableLineHeight));
return mWeekline;
}
下面就看其它的View
那就從上到下開始先看星期的布局
private void initView() {

mVerticalWeekLaout = new LinearLayout(getContext());
mVerticalWeekLaout.setOrientation(HORIZONTAL);
//表格

switch (i) {
case 0:
//課表出的0,0格子 空白的

mTime.setHeight(dip2px(TimeTableWeekNameHeight));
mTime.setWidth((dip2px(TimeTableNumWidth)));
mHorizontalWeekLayout.addView(mTime);
//繪制1~MAXNUM
LinearLayout mMonday = new LinearLayout(getContext());
ViewGroup.LayoutParams mm = new ViewGroup.LayoutParams(dip2px(TimeTableNumWidth), dip2px(MAXNUM * TimeTableHeight) + MAXNUM * 2);
mMonday.setLayoutParams(mm);
mMonday.setOrientation(VERTICAL);
for (int j = 1; j <= MAXNUM; j++) {
