之前有个项目要用到 日期选择器,于是百度了有关 方法,自己 将其 封装成了 自定义 控件
项目 地址:点击打开链接
Android 自带 的 日期选择器和时间选择器 为DatePicker 和 TimePicker,一个是 年月日选择器,一个是时分 选择 器。
而在 Android 不同 的 API 下 它们的 显示 样式 也不同。
因为 此次封装 是在 弹框中显示 的 ,所以选择 了 比较简单的 样式
DatePicker如果 要 显示 上图的 样式 ,在 xml 布局中 需如此 设置
android:id="@+id/datePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:calendarViewShown="false"
android:datePickerMode="spinner"/>
TimePicker 要显示上图 样式 ,则需要 用 代码 设置 布局 的 主题
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); Context contextThemeWrapper = new ContextThemeWrapper( getContext(), android.R.style.Theme_Holo_Light); LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper); View view = localInflater.inflate(R.layout.view_time_picker_dialog, null, false); timePicker = (TimePicker) view.findViewById(R.id.timePicker);
要 自定义Dialog的 布局 则需自己 通过 布局文件 实例化 view 然后 调用 setView()
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); Context contextThemeWrapper = new ContextThemeWrapper( getContext(), android.R.style.Theme_Holo_Light); LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper); View view = localInflater.inflate(R.layout.view_time_picker_dialog, null, false); setView(view);
这种效果 在 我的另一篇文章里有 点击打开链接
年月日 选择 如果 想 单纯 显示 年,月,日 或 隐藏 某一模块可以用
// 是否 显示 年 if (!this.isYearVisible) { ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(0).setVisibility(View.GONE); } // 是否 显示 月 if (!this.isMonthVisible) { ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(1).setVisibility(View.GONE); } // 是否 显示 日 if (!this.isDayVisible) { ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(2).setVisibility(View.GONE); }
完整 的 日期 选择 器 效果图 为
标题 为 RadioGroup,中间为 ViewPager,底部 为 LinearLayout 放入 两个Button
ViewPager有两页 ,一个 DatePicker, 一个TimePikcer
这是 布局 代码
这是 完整Dialog 的 代码
