有没有一种方法可以在 Android 首选项中更改字体样式、颜色？

Question

I have created custom preferences into my app, which uses SharedPreferences to save data and I used PreferenceActivity.

Now I need to modify its appearance. Including font style, color, and font type. If possible, add custom colors, background, add images, etc.

Can I do that? If so, how can I do it?

Answer 1

Start off by creating a custom style whose parent is the app's theme. styles.xml

<style name="PreferenceTheme" parent="AppTheme">
    <item name="fontFamily">@font/whatever</item>
    ...
</style>

Then, in your Settings class,

(if it extends PreferenceFragment, then do this in the onCreateView)

container.getContext().setTheme(R.style.PreferenceTheme);

(otherwise, if it extends PreferenceActivity, then do this in onCreate)

setTheme(R.style.PreferenceTheme);

Answer 2

First you create extend TextView class and create custom Typeface. Then go to style folder and create new style and set color and size there.
