Adding the dots at the end of Textview (...) , dots not showing

Whenever a text (That I set programmatically from an Activity) is longer than n charachters, I want to cut off and limit the texts length and add 3 dots at the end of the textview. Text is initially set to empty (just "") in xml, and is set from activity later.

This is how I tried:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text=""
    android:maxLength="10"
    android:ellipsize="end"
    android:maxLines="1"/>

This is how it ends up looking with a random text, and I set the maxlength to 10 charachters:

enter image description here

I was expecting it to look like jrkfkgkglg... because the text is jrkfkgkglggfgirng, but the dots are not added at the end. Any suggestions?

For this you have to remove the attribute

android:maxLines="1"

and add the new attribute

android:singleLine="true"

and in addition make your textview width match_parent. It will work properly when you will add this then you don't need to use anything else.

You are telling your edit text to be maximum 10 chars in length, in your screenshot, you have a string with that length so if you will try to add anything to that string it won't get added.

You can remove the android:maxLength="10" limit and check your text from your code programmatically, something like this:

if (yourText.length() > 10) {
    yourText = yourText.substring(0, 9); //get the first 10 chars
    textView.setText(yourText + "..."); //display 
} else {
    textView.setText(original string < 10chars);
}

In order for this to work, your width must be match_parent or have a any other size defined instead of being wrap_content.
