Button transparent background with border In some situations, android developers want to put a transparent background button in their app interface. Totally transparent background colored button can’t define the clicked area. So transparent button should have an opaque border color. It will render a solid color bordered button with a transparent background colored button widget. This android app development tutorial will show, how can an android developer render a transparent background color button with an opaque colored border. To achieve this widget, first, we put a Button widget in our XML layout file. Inside the Button tag, we have to put a property name background. The background property has a value that points to a drawable XML file. The main code is located in this XML drawable file. It has a selector with an item.

This tutorial will guide you to make a rounded corners button. The following code snippets consist of two XML files. The first is an activity XML file and another one is an XML drawable file. In the XML layout file, we put a background property inside the Button tag. The button’s background property value point to an XML drawable file that is located inside the drawable folder.

At first, in the XML layout file, we will put a background property inside the Button tag. The background property value point to an XML drawable file that actually draws the circle button in the app interface. XML drawable file selector holds an item that declares the shape of the actual widget. Here we define an oval shape to generate a circle Button.

The Button shows a default background color when users press it.Android developers can easily change the default background color of the button’s pressed state. In this android app development tutorial, we will see how can we change the button’s pressed state background color. First of all, we will write the background property on the Button widget XML file. The Button’s background property value points to an XML drawable file which includes a selector with the button’s different states colors and shapes values. Such as, Button’s default state, focused state, and pressed state’s background color. Within the selector pressed state’s item we will put a background color that we want to replace with the button’s default pressed state background color. Here we can also specify the button’s shape and corner radius. activity_main.xml ...

Month name from number The following asp.net c# example code demonstrate us how can we get month name from number. this examplecode also demonstrate us how can we get month name from a datetime object. bellow is the explain of example source code. We created a datetime object using DateTime.Today property. DateTime.Today property get the current date without time in the web server.DteTime.Month property gets the month number from a datetime object. so we uses the DateTime.Month property to get the month number fromtoday date that represent the current month of web server. At last we call the DateTimeFormatInfo.GetMonthName() method that returns the culture specific full name of the specified month based on theculture associated with the current DateTimeFormatInfo object. GetmonthName method require an integer type argument that represent month number. CultureInfo.DateTimeFormat property get or set a DateTimeFormatInfo that defines the cult...
