Xem hình ảnh dưới đây để biết cách làm việc android:ellipsize

Tôi đã sử dụng sau 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>
