The view is the component which Android provides us to design the layouts of the app. Here, we are going to start with XML (extensible markup language) and design a screen and understand what the different types of View Components Android Studio provided to us. So, in this blog, we will learn about User Interface(UI) in Android.
So, to make the UI of the application good, we need to learn about XML(Extensible Markup Language) and View components in Android. While (event != XmlPullParser.The Android application having an excellent UI will have a large number of users because usually, people get attracted towards the look and feel of the application. So XMLPullParser has a separate function for parsing each of the component of XML file. An XML file consist of events, Name, Text, AttributesValue e.t.c. In our case it is a stream.Its syntax is given below − The next step involves specifying the file for XmlPullParser that contains XML. Private XmlPullParser myparser = xmlFactoryObject.newPullParser() Private XmlPullParserFactory xmlFactoryObject = XmlPullParserFactory.newInstance() In the next step, we will create XMLPullParser object, but in order to create that we will first create XmlPullParserFactory object and then call its newPullParser() method to create XMLPullParser. Such as GB is a text in the country tag.Īttributes are the additional properties of a tag such as value e.t.c Document starts, Document ends, Tag start, Tag end and Text e.t.cĪpart from tags and events, and xml file also contains simple text. The first line that contains the information about a file is prologĪn XML file has many events. Here is the table defining the components of an XML file and their description. In the XML given below we interested in getting temperature only.Īn xml file consist of many components. The first step is to identify the fields in the XML data in which you are interested in. So we are going to use XMLPullParser for parsing XML. Among all of them android recommend XMLPullParser because it is efficient and easy to use.
