How to set EditText to show suspension points in the last line without cut the text out of bounds

I have an EditText view with a bounded size of 300dp * 300dp.

This EditText is used to show a preview of some descriptions received from a server, so if the text is too long appears cut in the last line. I want that in case of too long text, in the end of the last fully visible line are showed suspension points to avoid bad truncation

example

if for the text

Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua.

If the max visible text is only

Lorem ipsum dolor sit amet, consectetur adipisici elit,

The EditText should show

Lorem ipsum dolor sit amet, consectetur adipisici...

Any solutions?

You can measure the width of a text using measureText from the Paint class. If the text is too long for the view, just search for the substring that fit that width.

For example, if view is the EditText :

String text = "Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua.";
String subtext = text;
Paint paint = view.getPaint();

while( paint.measureText(subtext) > view.getWidth() ) {
    subtext = subtext.substring(0, subtext.lastIndexOf(' '));
}

view.setText(subtext + "...");

If your message is a description obtained from a server and it is rather useless to edit it by the user, why not using TextView instead?

    <TextView
        ...
        android:ellipsize="end"
        android:singleLine="true" />

Same you can achieve with EditText, but you have to set also android:editable="false".
