Android Code Snippet Force Consistent Layout (Ignore System Font and Display Scale)

Hi everyone,

One of the biggest challenges in UI/UX design for Android is when the user changes the Font Size (Acessibility) or Display Size (Scaling) in the system settings. This often breaks carefully designed layouts, especially when using fixed-size panels or labels.

This snippet, added to your Activity, forces the app to render at 100% font scale and uses the device's native density, ignoring system-wide overrides.

Add this to your Main Activity (or any Activity that needs to stay consistent):

#If JAVA
import android.content.Context;
import android.content.res.Configuration;
import android.content.res.Resources;

@Override
protected void attachBaseContext(Context newBase) {
    Resources res = newBase.getResources();
Configuration config = new Configuration(res.getConfiguration());
  
// 1. Fix Font Scale to 100% (Ignores "Large Text" settings)
config.fontScale = 1.0f;
  
// 2. Fix Density (DPI) to the device's native default
// This prevents "Display Size" changes from breaking layouts
    config.densityDpi = res.getDisplayMetrics().densityDpi;
  
    Context context = newBase.createConfigurationContext(config);
    super.attachBaseContext(context);
}
#End If
