Android: TextView automatically truncate and replace last 3 char of String


If a String is longer than the TextView's width it automatically wraps onto the next line. I can avoid this by using android:singleLine (deprecated) or by setting android:inputType="text". What I need now is something that replaces the last 3 characters of my String with "...". Since I'm not using a monospace font this will always be different depending on the letters used in my String. So I'm wondering what's the best way to get the last 3 characters of a String in a TextView and replace them. Maybe there's already something implemented in the Android framework, since this must be a common problem.


Solution

  • You should be able to use the "ellipsize" property of a text view:

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/text_mytext"
        android:ellipsize="end"
        android:maxLines="1"
    />
    

    You may also need to apply gravity values to the layout too; I have sometimes seen "auto-stretching" views without them.
