android 自定义view画表格,Android自定义View实现课程表表格

自己闲下来时间写的一个课表控件，使用的自定义LinearLayout，里面View都是用代码实现的，最终效果如下图，写的可能有问题希望多多指点

059a3cc0d9dfa1e42706e0414893d74b.png

创建一个自定义LinearLayout 控件用来装载课程的信息和课程的周数，和节数大概的布局三这样的

050b7c0a81ebd892dd038f6c501bbccb.png

根据上面的看来觉得总体布局我分了两个 上面的星期是一个 下面的节数和格子是一个  总体使用Vertical  而单独内部者使用了Horizontal布局  中间使用了两种布局线条 是这样的

/**

* 横的分界线

*

* @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;

}

/**

* 竖向分界线

*

* @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

那就从上到下开始先看星期的布局

private void initView() {

mHorizontalWeekLayout = new LinearLayout(getContext());

mHorizontalWeekLayout.setOrientation(HORIZONTAL);

mVerticalWeekLaout = new LinearLayout(getContext());

mVerticalWeekLaout.setOrientation(HORIZONTAL);

//表格

for (int i = 0; i <= WEEKNUM; i++) {

switch (i) {

case 0:

//课表出的0,0格子 空白的

TextView mTime = new TextView(getContext());

mTime.setHeight(dip2px(TimeTableWeekNameHeight));

mTime.setWidth((dip2px(TimeTableNumWidth)));

mHorizontalWeekLayout.addView(mTime);

//绘制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++) {

TextView mNum = new TextView(getContext());

mNum.setGravity(Gravity.CENTER);

mNum.setTextColor(getResources().getColor(R.color.text_color));

mNum.setHeight(dip2px(TimeTableHeight));

mNum.setWidth(dip2px(TimeTableNumWidth));

mNum.setTextSize(14);

mNum.setText(j + "");

mMonday.addView(mNum);

mMonday.addView(getWeekTransverseLine());

mHoriView.addView(mWeekName);
