1. First, let's look at the implementation results:

Click date "". The select date dialog box is displayed.

Click time. The time dialog box is displayed.

II. The Code is as follows:

1. xml file

<? Xml version = "1.0" encoding = "UTF-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: orientation = "horizontal" android: layout_width = "fill_parent" android: layout_height = "fill_parent"> <TextView android: id = "@ + id/txtDate" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: text = "click to set date"/> <TextView android: id = "@ + id/txtTime" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_marginLeft = "2dp" android: text = "click to set the time"/> </LinearLayout>

2. The background code is as follows:
