I have a TextView (who doesn’t?) and I want to adjust its height automatically, depending on the length of the text it will contain. Should be easy. It was, but it took me a couple of minutes to figure it out.

So I want my TextView to be by default one line tall, but be able to expand up to two lines. My initial set up was to set lines=1 and maxLines=2, but it was making the TextView always two lines. Not what I wanted! I went through the documentation again, read each word carefully, and then:

<TextView android:id="@+id/title" 
          android:text="This is the text" />

So it turned out that you have to set both minLines and maxLines. TADA!
