Android Auto Fit Button automatically resizes text to fit perfectly within its bounds. It takes into consideration button paddings and drawables.

Setup

Installation

allprojects {
    repositories {
        jcenter()
        maven {
            url  "http://dl.bintray.com/marcouberti/maven"
        }
    }
}

Add this to your app build.gradle file:

dependencies {
    ...
    compile 'com.marcouberti.autofitbutton:android-auto-fit-button:0.1.1@aar'
    ...
}

Basic usage

In order to use the auto fit button you simply have to use it inside your layout XML file like this:

<com.marcouberti.autofitbutton.AutoFitButton
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:textSize="20sp"
        android:text="CLICK HERE"/>

Custom attributes

There is a custom attribute minTextSize you can use to prevent the text become too small. To use it ensure to import the correct namespace:

xmlns:custom="http://schemas.android.com/apk/res-auto"

And than use it like this:

<com.marcouberti.autofitbutton.AutoFitButton
		custom:minTextSize="4sp"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:textSize="20sp"
        android:text="CLICK HERE"/>

Known issues

• When using wrap_content the height of the button may not adapt accordingly to the new computed text size. It is strongly suggested to set fixed button dimensions or to use match_parent.
