Can I limit TextView's number of characters?

What I have now is a ListView of TextView elements. each TextView element displays a text (the text length varies from 12 words to 100+). What I want is to make these TextViews display a portion of the text (let's say 20 word or roughly 170 chars).

How to limit the TextView to a fixed number of characters?

Solution

  • Here is an example. I limit the sizewith the maxLength attribute, limit it to a single line with maxLines attribute, then use the ellipsize=end to add a "..." automatically to the end of any line that has been cut-off. 

    <TextView 
    android:id="@+id/secondLineTextView" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:maxLines="1" 
    android:maxLength="10" 
    android:ellipsize="end"/>
