How to get number of lines of TextView?

Question

I want to get the number of lines of a text view

textView.setText("Test line 1 Test line 2 Test line 3 Test line 4 Test line 5.............") 

textView.getLineCount(); always returns zero

Then I have also tried:

ViewTreeObserver vto = this.textView.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {      @Override     public void onGlobalLayout() {         ViewTreeObserver obs = textView.getViewTreeObserver();         obs.removeGlobalOnLayoutListener(this);         System.out.println(": " + textView.getLineCount());      } }); 

It returns the exact output.

But this works only for a static layout.

When I am inflating the layout dynamically this doesn't work anymore.

How could I find the number of line in a TextView?

Answer 1

I was able to get getLineCount() to not return 0 using a post, like this:

textview.setText(“Some text”); textview.post(new Runnable() {     @Override     public void run() {         int lineCount = textview.getLineCount();         // Use lineCount here     } });

As mentioned in this post,

getLineCount() will give you the correct number of lines only after a layout pass.

It means that you need to render the TextView first before invoking the getLineCount() method.
