实现
val etTime = findViewById<EditText>(R.id.user_et_time)
val datePickerHelper = DatePickerHelper(this)
// 将日期选择器附加到 user_et_time EditText 上
// 设置 EditText 的点击事件监听器
etTime.setOnClickListener {
datePickerHelper.showDatePickerDialog(etTime)
}
//对应格式
val date = datePickerHelper.formatDate(selectedDate)
<EditText
android:id="@+id/user_et_time"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/user_tv_grade"
android:layout_below="@id/user_et_grade"
android:hint="请输入日期"
android:minLines="2"/>
