• Simple Builder pattern
• Includes three styles (incl. Material Design Snackbar)
• Supports API Level >= 8 (using nineoldandroids)
• I18N (about ~100 languages)

• pre KitKat

• KitKat

• Lollipop and later

• It's as simple as:

new UndoBar.Builder(this)//
  .setMessage("X items deleted.")//
  .setListener(this)//
  .show();

• You can also explicitly use one of the styles shown above. This is useful, for example, if you want to show a consistent Material Design style across all API levels. By default, it uses the style of the device's current API level. Here's an example:

new UndoBar.Builder(this)//
  .setMessage("X items deleted.")//
  .setListener(this)//
  .setStyle(UndoBar.Style.LOLLIPOP)//
  .show();

Grab it via Gradle:

For API Level >= 15:

compile 'com.github.jenzz.undobar:library:1.3:api15Release@aar'

For API Level < 15 (includes nineoldandroids):

compile 'com.github.jenzz.undobar:library:1.3:api8Release@aar'
