In "Settings", "Show", "Font size" We can set the system font size

The app interface font, if modified, may not achieve the desired effect, the interface layout has changed.

Unmodified effect (Test model: Nexus 5):

Normal small Super big

Effect after modification (test model: Nexus 5):

Normal small Super big

From these two sets of comparison charts, we can visually see that the modified app font size does not change with the system changes.

In fact, it is easy to implement, without having to set the "TextSize" in the layout file, simply rewrite the Getresources () method in the parent activity:

@Override      Public Resources getresources () {        super. getresources ();         New Configuration ();        Configuration.settodefaults ();        Resources.updateconfiguration (Configuration, Resources.getdisplaymetrics ());         return resources;    }
