Android: Ellipsise, смысл опций

Я видел, что мы можем установить 4 значения в android:ellipsize, например:

нет, начало, середина, конец и область выделения

В чем смысл и эффект установки каждого из них?

См. изображение ниже, чтобы узнать, как работает android:ellipsize enter image description here

Я использовал следующий xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:maxLines="4" 
android:ellipsize="none" 
android:singleLine="false" 
android:text="Hi make this a very long string that wraps at least 4 lines, seriously make it really really long so it gets cut off at the fourth line not joke.  Just do it!" 
android:layout_marginBottom="25dip"
/>
<TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:maxLines="4" 
android:ellipsize="start" 
android:singleLine="false" 
android:text="Hi make this a very long string that wraps at least 4 lines, seriously make it really really long so it gets cut off at the fourth line not joke.  Just do it!" 
android:layout_marginBottom="25dip"/>
<TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:maxLines="4" 
android:ellipsize="middle" 
android:singleLine="false" 
android:text="Hi make this a very long string that wraps at least 4 lines, seriously make it really really long so it gets cut off at the fourth line not joke.  Just do it!" 
android:layout_marginBottom="25dip"/>
<TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:maxLines="4" 
android:ellipsize="end" 
android:singleLine="false" 
android:text="Hi make this a very long string that wraps at least 4 lines, seriously make it really really long so it gets cut off at the fourth line not joke.  Just do it!" 
android:layout_marginBottom="25dip"/>


<TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:maxLines="4" 
android:ellipsize="marquee" 
android:text="Hi make this a very long string that wraps at least 4 lines, seriously make it really really long so it gets cut off at the fourth line not joke.  Just do it!" />

</LinearLayout>
