  1. Creating a simple text layout:
TextLayoutBuilder builder = new TextLayoutBuilder()
    .setText("Hello, World!")
    .setTextColor(Color.BLACK)
    .setTextSize(16)
    .build();
  1. Adding multiple styles to a single text layout:
TextLayoutBuilder builder = new TextLayoutBuilder()
    .setText("Hello, World!")
    .setTextColor(Color.BLACK)
    .setTextSize(16)
    .addTextStyle(new TextStyle(0, 5)
        .setTextColor(Color.RED)
        .setTextSize(20))
    .build();
  1. Using custom fonts:
Typeface customFont = Typeface.createFromAsset(getAssets(), "fonts/custom_font.ttf");
TextLayoutBuilder builder = new TextLayoutBuilder()
    .setText("Custom Font Text")
    .setTypeface(customFont)
    .setTextSize(18)
    .build();

Getting Started

To use TextLayoutBuilder in your Android project:

  1. Add the dependency to your app's build.gradle file:
dependencies {
    implementation 'com.facebook.fbui.textlayoutbuilder:textlayoutbuilder:1.4.0'
}
  1. In your Java code, import and use the TextLayoutBuilder:
import com.facebook.fbui.textlayoutbuilder.TextLayoutBuilder;

// ...

TextLayoutBuilder builder = new TextLayoutBuilder()
    .setText("Your text here")
    .setTextColor(Color.BLACK)
    .setTextSize(16)
    .build();

// Use the built layout in your custom view or drawing code

TextLayoutBuilder

Build text Layouts easily on Android.

Features

  • Create text Layouts easily.
  • Reuse builders to create similarly styled Layouts.
  • Cache Layouts of commonly used strings.
  • Improve performance by warming up the FreeType cache.

Download

If using Gradle, add this to your build.gradle:

compile 'com.facebook.fbui.textlayoutbuilder:textlayoutbuilder:1.7.0'

or, if using Maven:

<dependency>
  <groupId>com.facebook.fbui.textlayoutbuilder</groupId>
  <artifactId>textlayoutbuilder</artifactId>
  <version>1.7.0</version>
  <type>aar</type>
</dependency>

Usage

  1. Set the properties on the TextLayoutBuilder:
TextLayoutBuilder builder = new TextLayoutBuilder()
    .setText("TextLayoutBuilder makes life easy")
    .setTextColor(Color.BLUE)
    .setWidth(400 /*, MEASURE_MODE_EXACTLY */);
  1. Call build() on the builder to get a Layout:
Layout layout = builder.build();
  1. Use the Layout in your code:
public class CustomView extends View {
    private Layout layout;

    public CustomView(Context context) {
        super(context);
    }

    public void setLayout(Layout layout) {
        this.layout = layout;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        // Draw the layout.
        layout.draw(canvas);
    }
}

Additional Usage

  1. Cache the layouts for commonly used strings by turning on caching in the TextLayoutBuilder.
textLayoutBuilder.setShouldCacheLayout(true);
  1. Glyph warming provides significant performance boost for large blurbs of text. Turn this on and pass in a GlyphWarmer for the TextLayoutBuilder.
textLayoutBuilder
    .setShouldWarmText(true)
    .setGlyphWarmer(new GlyphWarmerImpl());
  1. Import a style defined in XML into a TextLayoutBuilder object.
ResourceTextLayoutHelper.updateFromStyleResource(
    textLayoutBuilder, // builder object
    context,           // Activity context
    resId);            // style resource id
