No title bar and xml loading strangely

I have downloaded android studios before but i tried uninstalling and deleting files because whenever i create a new project the xml loads strangely (still functional). The code will look like android:something android:something android: tools android:something (it doesn't actually say something). The formatting is strange. Also, I don't see the title bar at the top with a Android icon. I just see the text box screen saying "Hello World". Is there something wrong with my files?

Thank you

I had a problem on linux before. Not Windows 8. Sorry to say but I can't help with this one. If no-one can help with this, try asking stackoverflow. They may have people who know a little bit more into the IDE and how to fix this rather than problems with code. Not saying there's anyone here who knows how to fix this.

Matthew;

Here is what my XML looks like as a new project with no edits:

activity_main.xml 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:paddingLeft="@dimen/activity_horizontal_margin"
                android:paddingRight="@dimen/activity_horizontal_margin"
                android:paddingTop="@dimen/activity_vertical_margin"
                android:paddingBottom="@dimen/activity_vertical_margin"
                tools:context=".MainActivity">

    <TextView
        android:text="@string/hello_world"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</RelativeLayout>

and the manifest:

AndroidManifest.xml 
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zyzzyxtech.testhelloworld" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Is that what yours looks like?
