I saw we can set 4 values to android:ellipsize such as:

none,start,mid,end and marquee

What is the meaning and effect of setting each of these?

See the below image to know how android:ellipsize works

I have used following 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>
