I believe the TextView has a method getLineCount which you can use to get the number of lines. You can compare that function's return value with maxLines and show/hide if the limit is reached.

See also: TextView.getLine()

And: TextView - maxLines attribute

Use a thread to count the number of lines, 

 textView.setText("Text Here");
    textView.post(new Runnable() {

        @Override
        public void run() {

            Log.v("Line count: ", textView.getLineCount()+"");
        }
    });

If you want to limit the number of lines in TextView from xml then use android:maxLines
