cd.get(Calendar.MONTH),
cd.get(Calendar.DAY_OF_MONTH)).show();

et.setOnFocusChangeListener(new OnFocusChangeListener(){

嗯 可以的
你可以设置EditText的触发监听事件
我研究过，这个是在View里定义onTouchEvent()的默认处理逻辑。假如一个View是可以获得焦点的话，那么第一次点击操作就是获取焦点。这里有源代码： boolean focusTaken = false;
if (isFocusable() && isFocusableInTouchMode() && !isFocused()) {
focusTaken = requestFocus();
}
if (!mHasPerformedLongPress) {
// This is a tap, so remove the longpress check
removeLongPressCallba（）;
// Only perform take click actions if we were in the pressed state
if (!focusTaken) {
// Use a Runnable and post this rather than calling
// performClick directly. This lets other visual state
// of the view update before click actions start.
if (mPerformClick == null) {
mPerformClick = new PerformClick();
}
if (!post(mPerformClick)) {
performClick();
}
}
}所以如果你想改变这个的话，只能自己重新实现一个onTouchEvent()而不调用super.onTouchEvent()，具体需要注意哪些东西需要你自己参考源代码，不然可能有些必须的处理过程就会漏掉了

为什么要用edittext呢，反正是设置日期，你可以用button，然后设置button 的onclick事件，点击button出现DatePickerDialog，最好dialog里有两个按钮，确定和取消，点击确定把所选择的值赋给button的Text
