Text Size for Different Resolution Density Just Using XML

Question

How do we change the textSize based on Resolution density?

I have found several ways on SO, but all of them usng java code to do that.

I however need a java free approach because I have someplaces where I set a textSize on XML and some on Java code.

In xml, I do this

        android:textSize="@dimen/FONT_SIZE_SMALL"

however sometimes I need to set it via java code.

        textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimension(R.dimen.FONT_SIZE_SMALL);

Any ideas please? is it doable?

Use textSize in sp unit in xml. It will adjust to all resolutions.

Hope this helps.

UPDATE Please also refer to Text size with different resolution which proposes some scaling factors for different resolutions.

Yes, that is what I have been doing – JayVDiyk Jan 21 '16 at 11:48
That should suffice your needs. What else do you need? – Anirudh Murali Jan 21 '16 at 11:50
Doesn't this fulfill your need? – Mustansar Saeed Jan 21 '16 at 11:51
@MustansarSaeed No, cause sometimes I had to use Java when setting text Size. (i.e.: When I request data from server). I have edited the question – JayVDiyk Jan 21 '16 at 11:52

Have a look at this: http://stackoverflow.com/questions/7157069/how-to-change-the-font-size-and-font-color-from-the-java-file Is this what you're looking for? – Anirudh Murali Jan 21 '16 at 11:55
Are you using single layout file or different for different DPIs? – Mustansar Saeed Jan 21 '16 at 11:55

You can declare sizes with the <dimen> tag in dimens.xml in resolution specific values folder.
eg

<dimen name="my_text_view_size">12sp</dimen>

You can have multiple value files for different resolutions and can assign different values for the same constant for each resolution. then assign the constant to textsize.
