This article explains how to apply custom fonts, enable AutoLink, and use justification mode in Android TextView, providing step‑by‑step code examples for assets and res/font resources, XML attributes, and runtime settings for developers.
The article explains how to give privileged Android live‑chat users gradient nicknames by applying a LinearGradient shader via a custom GradientColorSpan, handling multi‑line text with restart or continuous strategies, and integrating these spans in a LiveGradientTextView that measures, inflates, and renders the gradient consistently across all live‑room scenarios.
This article demonstrates how to build a custom Android TextView that supports clickable topic spans, URL interception, and smooth expand‑collapse behavior using StaticLayout measurements, custom ButtonSpan labels, and optional height‑animation, providing a reusable solution for rich mobile text displays.
The article shows how to diagnose the Android 6.0+ TextView marquee jump caused by a button’s setText triggering requestLayout and onMeasure, and fixes it by giving the button a fixed size instead of wrap_content, illustrating a systematic source‑code analysis and debugging workflow for UI issues.
This article investigates an Android ANR triggered by a while‑true loop in TextView's getOffsetForHorizontal, reproduces the issue on Pixel 2, explains how to extract trace files, compares Android Studio debugging with Frida dynamic hooking, and provides step‑by‑step instructions to reproduce and debug the bug.
The article explains why Android TextView line spacing varies across devices due to mismatched FontMetrics calculations, and presents a low‑intrusion fix that uses a custom LineHeightSpan applied via an ETextView subclass to enforce a visual‑consistent line height equal to the text size on all screen resolutions.
To solve Android’s screen‑fragmentation‑induced TextView line‑spacing inconsistencies, Baidu’s team analyzed the default line‑height calculation, then created a custom LineHeightSpan (ExcludeInnerLineSpaceSpan) applied through a subclassed ETextView to enforce visual‑defined line height, delivering a simple, low‑intrusion, cross‑resolution fix.
This article explains how Android's TextView renders text, detailing its coordinate system, layout classes, span types, HTML conversion, and practical implementations such as custom ReplacementSpan and link handling within the Snowball app, providing developers with a comprehensive guide to advanced text styling.
