Android XML Parsing Tutorial

If you would like package fixed XML together with your application, you need to use an XML useful resource. Simply put the actual XML document inside res/xml/, and you may access it simply by getXml() with a Resources object, providing it a resource ID of R.xml. in addition to the base name of your respective XML file.

Creating Layout for XML Parsing Example

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" >
  <TextView
    android:id="@+id/selection"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
  />
  <ListView
    android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:drawSelectorOnTop="false"
  />
</LinearLayout>

res/raw/my_words.xml

<words>
  <word value="Android" />
  <word value="Amazon"/>
  <word value="America"/>
  <word value="Bluetooth" />
  <word value="Brazil"/>
  <word value="Baseball"/>
  <word value="Chrome" />
  <word value="Cricket"/>
  <word value="Docs" />
  <word value="Denamrk"/>
  <word value="Email" />
  <word value="England"/>
  <word value="Facebook" />
  <word value= "France"/>
  <word value="Google" />
  <word value="Gmail"/>
  <word value="Greece"/>
  <word value="Germany"/>
  <word value="Hungary" />
  <word value="Iphone" />
  <word value="India"/>
  <word value="Internet"/>
  <word value="Japan"/>
  <word value="Korea" />
  <word value="London"/>
  <word value="Machintosh" />
  <word value="Nokia" />
  <word value="Norway"/>
  <word value="Orkut" />
  <word value="Olive"/>
  <word value="Picasa" />
  <word value="Singapore" />
  <word value="Talk" />
  <word value="VimalTuts"/>
  <word value="Victoria"/>
  <word value="Windows" />
  <word value="Willington"/>
  <word value="Wipeout"/>
  <word value="White Collar"/>
  <word value="X-Mas"/>
  <word value="Youtube" />
  <word value="Zimbabwe"/>
</words>
