How to change font in a Listview?

Postby askdon2001 » Tue Jan 13, 2009 3:54 pm

Hi,

I am new to Android Development, and trying to develop a sample application. I have been trying to change the font within the listview, but I am unable to do it. I have tried googling the topic, but unable to find a solution.

Please see the attached image to see what I want to do. I want to have different fonts within the same Listview.

Best Regards,

Akash Dongre

You can't change the font in a ListView as a ListView doesn't have a font. You need to change the font of the TextViews you use to display text in the ListView.

Thanks MrShowflake, but can I have different fonts? How do I change those?

I will try few things and will get back again.

Btw is their any link, where I can see all the attributes which can are used for Layouts. I really don't like the way Google has made the current API Doc.

Best Regards,

Actually, I want to change the font of the text which is sent to a ArrayAdapter. The text is added to the arrayadapter using toString(), but how to have different fonts for the text which is added using toString().

Thanks in advance.

The ArrayAdapter takes the resource Id of a layout which will be used to display the items in the array, so you have to make your own layout with the textviews you want (and of course your wanted font).

Thanks in advance again.

Then you have to make a layout which has 2 TextViews (@android:id/text1 and @android:id/text2) with 2 different fonts... (Don't forget to put them both in a ViewGroup).

And you should really use proper capitalization, instead of: String getaddress() do String getAddress(). It makes your life a lot easier. You probably knew this already, as you did some of them correctly :).

Thanks Snowflake.

But unfortunately, I am still stuck. I don't know how to put TextView in a viewgroup. Also, what will go into arrayadaptor?

I have tried making two list and tried to put them, but go error.

Can you please let me know about some example of putting TextView in ViewGroup.

Thanks and Regards,
