IconButton for Android

IconButton is an Android button widget that allows you to center both the button's text and an icon.

Android's stock Button class allows you to assign a Drawable to the left, right, top, or bottom of a button, but it looks bad if you need to have the button fill the screen:

Installation

For Gradle / Android Studio

Make sure you declare the JCenter repository in your project's build.gradle:

repositories {
    jcenter()
}

Then add a compile-time dependency on this library, adding the dependencies section to build.gradle if it doesn't already exist:

dependencies {
    compile 'com.githang:com-phillipcalvin-iconbutton:1.0.1@aar'
}

For Old Version

If you're using ADT, clone this repository and import it into your workspace using File - Import. Then add it to your project by right-clicking your project, selecting Properties, then Android, and adding IconButton in the references list at the bottom of the Properties window.

If you're not using ADT, I recommend using this library as a submodule:

git submodule add [email protected]:pnc/IconButton.git

Generate a local.properties for IconButton:

android update project -n IconButton --path IconButton/IconButton

Then reference the library from your own project.properties:

android.library.reference.1=IconButton/IconButton

If you already have library references, change the 1 to the appropriate number.

Usage

In your layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/your.project.package"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

<!-- ... -->

  <com.phillipcalvin.iconbutton.IconButton
      android:id="@+id/search"
      android:drawableLeft="@drawable/action_search"
      android:text="@string/search"
      app:iconPadding="10dp" />

The use of app:iconPadding is optional. It allows you to add padding between the drawable and your text.

Change the text your.project.package to your own project's package. You don't have to use LinearLayout, but you do need to make sure to define the namespace definition (xmlns:app="http://schemas.android.com/apk/res/your.project.package") appears in the root element.

You can assign either a drawableLeft or a drawableRight to the IconButton.

Caveats

IconButton only supports one drawable on the left or right. I'll absolutely accept patches that improve its handling of multiple drawables.
