Deprecated

The SmartLayoutInflator is deprecated. No more development will be taking place. In order to play with fonts and typefaces use the fonts in XML feature available in the Support Library 26.0 and supported in Android Studio 3.0

SmartLayoutInflator

The SmartLayoutInflator is a component which enables to tune the Android LayoutInflater and play with Typeface.

Usage

1. Declare the fonts used in your app as typefaces

In order to declare the fonts used into your app as Typefaces, you should create your own class using the SimpleTypefaceable class :

public final class Typefaces
    extends SimpleTypefaceable
{

   public static final Typefaces RobotoBold = new Typefaces(TypefaceLocation.Assets, "Roboto-Bold.ttf");

   public static final Typefaces RobotoCondensedRegular = new Typefaces(TypefaceLocation.Assets, "RobotoCondensed-Regular.ttf");

  public static final Typefaces RobotoLight = new Typefaces(TypefaceLocation.Assets, "Roboto-Light.ttf");

  public static final Typefaces RobotoMedium = new Typefaces(TypefaceLocation.Assets, "Roboto-Medium.ttf");

  public static final Typefaces RobotoItalic = new Typefaces(TypefaceLocation.Assets, "Roboto-Italic.ttf");

  private Typefaces(TypefaceLocation location, String fileName)
  {
    super(location, fileName);
  }

}

In order to optimize the performance of your app, you can then declare a static instance of this class directly into your Application class :

public final class LayoutInflatorApplication
    extends Application
{

  public static final class Typefaces
      extends SimpleTypefaceable
  {

    public static final Typefaces RobotoBold = new Typefaces(TypefaceLocation.Assets, "Roboto-Bold.ttf");

    public static final Typefaces RobotoLight = new Typefaces(TypefaceLocation.Assets, "Roboto-Light.ttf");

    public static final Typefaces RobotoRegular = new Typefaces(TypefaceLocation.Assets, "Roboto-Regular.ttf");

    private Typefaces(TypefaceLocation location, String fileName)
    {
      super(location, fileName);
    }

  }

  private static TypefaceManager<Typefaces> typefaceManager;

  public static TypefaceManager<Typefaces> getTypefaceManager()
  {
    if (typefaceManager == null)
    {
      typefaceManager = new TypefaceManager<>();
    }
    return typefaceManager;
  }

}

2. Declare the same fonts as XML attributs

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <declare-styleable name="Widgets">
    <attr name="android:textStyle"/>
    <attr name="typeface">
      <enum
        name="RobotoBold"
        value="0"
      />
      <enum
        name="RobotoCondensedRegular"
        value="1"
      />
      <enum
        name="RobotoLight"
        value="2"
      />
      <enum
        name="RobotoMedium"
        value="3"
      />
      <enum
        name="RobotoItalic"
        value="4"
      />
    </attr>
  </declare-styleable>
</resources>

3. Override the LAYOUT_INFLATER_SERVICE into your Activity

You have the override the getSystemService and return a SmartLayoutInflater :

@Override
public Object getSystemService(String name)
{
  if (Context.LAYOUT_INFLATER_SERVICE.equals(name) == true)
  {
    final LayoutInflater defaultLayoutInflator = (LayoutInflater) super.getSystemService(name);
    return SmartLayoutInflater.getLayoutInflater(defaultLayoutInflator, this, this);
  }

  return super.getSystemService(name);
}

The static method SmartLayoutInflater#getLayoutInflater takes 3 parameters :

• defaultLayoutInflater: the default LayoutInflater
• activity: the current Activity
• onViewInflatedListener: an implementation of the OnViewInflatedListener interface

4. Implement the OnViewInflatedListener interface

This interface exposes only one method onViewInflated which is called each time a widget is inflated. Here you can set the typeface of your widget :

@Override
 public void onViewInflated(Context context, View view, AttributeSet attrs)
{
  if (view instanceof TextView)
  {
    final TypedArray typedArray = obtainStyledAttributes(attrs, R.styleable.Widgets);
    final int typeface = typedArray.getInt(R.styleable.Widgets_typeface, 0);
    final TextView textView = (TextView) view;
     typedArray.recycle();
     switch (typeface)
    {
      case 0:
        textView.setTypeface(LayoutInflatorApplication.getTypefaceManager().getTypeface(getApplicationContext(), Typefaces.RobotoBold));
        break;
      case 1:
        textView.setTypeface(LayoutInflatorApplication.getTypefaceManager().getTypeface(getApplicationContext(), Typefaces.RobotoLight));
        break;
      case 2:
        textView.setTypeface(LayoutInflatorApplication.getTypefaceManager().getTypeface(getApplicationContext(), Typefaces.RobotoRegular));
        break;
    }
  }
}

Other features

• Activate the debug mode in order to display logs :

SmartLayoutInflater.DEBUG_LOG_ENABLED = true;

Know issues
