Use the functions in TextViewCompat instead those on TextView directly.Use the app namespace for XML attributes.The differences to the framework API are minimal: Thankfully, all of the auto-sizing functionality is available in the AndroidX core package (formerly Support Library). There are three distinct ways of enabling auto-sizing on a TextView, with increasing levels of specificity: Default, Granular and Preset.Īt the time of this writing, the chances of anyone having a minSdk of 26 are quite slim.

It can be implemented in XML layouts or programmatically. The TextView auto-sizing API is fairly concise. In these scenarios, TextView auto-sizing is precisely what we need. The text can’t scroll and we can’t just add a 'read more' button. Examples include a newspaper-style layout, a font selector that needs to show each different font typeface/name on a single-line, etc.

However, consider the case where the width and/or height of the text bounds are fixed and the text needs to adapt to the available space. When is this needed? 🤔įor Android Development, using a fixed textSize, layout_width='match_parent” and layout_height='wrap_content” (perhaps inside a scrollable parent) is fairly common practice and suitable for most TextView use cases. It offers a simple yet powerful API to solve a particular problem: scaling of text size to fit text bounds.

Import auto-sizing was introduced to the framework with Android 8.0 Oreo (API 26). Create three TextView widgets with different text sizes.

Ĭreate an Android Application with Kotlin support and Empty Activity. If the length of text exceeds the maximum length, then the text is truncated to the specified length. To set the maximum length for text in TextView widget, set the maxLength attribute with required number of length.
