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 the TextView in some way. Do 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 (...)
