This is my java class. The following xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

I am trying to parse a XML document and the values put in a ArrayList, and then preview the ArrayList items in a ListView but I am getting a lot of errors. Can someone tell me what am I doing wrong?
R.layout.carproileview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="schemas.android.com/apk/res/android"; android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:gravity="center">
<TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Large Text" android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
