What does ellipsize mean in android?

Question

You can find documentation here.

Based on your requirement you can try according option.

to ellipsize, a neologism, means to shorten text using an ellipsis, i.e. three dots ... or more commonly ligature …, to stand in for the omitted bits.

Say original value pf text view is aaabbbccc and its fitting inside the view

start's output will be : ...bccc

end's output will be : aaab...

middle's output will be : aa...cc

marquee's output will be : aaabbbccc auto sliding from right to left

In my experience, Ellipsis works only if the below two attributes are set.

android:ellipsize="end"
android:singleLine="true"

for the width of TextView, wrap_content or match_parent should both be good.

android:ellipsize added in API Level 1. An ellipsis is three periods in a row. (...) .

In your .xml

 <TextView
       ....
       android:text="Hi I am Amiyo, you can see how to ellipse works."
       android:ellipsize = "end" />

At this point, the ellipsis will not display yet as a TextView is set to automatically expand on default when new text is entered. You will need to limit TextView in some way. Do this, you can use either add to your TextView a scrollHorizontally, minLines, or maxLines to have the ellipsis display.

To make the ellipse:

    at the end: this is how it would.   
    use: android:ellipsize = "end"

And

 in the middle:
 use: android:ellipsize = "middle"

And

 at the start:
 use: android:ellipsize = "start"

And

 to have no ellipse
 use: android:ellipsize = "none"

Note Please :

Do not use android:singeLine = "true", it is deprecated.
android:maxLines = "1" will not display the three dots (...)
android:lines = "1" will not display the three dots (...)

An ellipsis is three periods in a row...

The TextView will use an ellipsis when it cannot expand to show all of its text. The attribute ellipsized sets the position of the three dots if it is necessary.
