How to use this library

  • Download this library, import to your IDE (eclipse...) as a library project.

  • Using Gradle(from 0.5)

    compile 'com.cocosw:undobar:1.+@aar' 
  • Using Maven



  • You can also use UndoBar with builder style.

    new UndoBar(getActivity()).message("Undo-bar title").listener(listener).show();
  • Or you can use UndoBar by just one line code (Deprecated from 1.4)

    UndoBarController.show(getActivity(), "Undo-bar title" , listener, undoToken);
  • UndoBar support customize style with background/icon/duration/animation attribution.

  • UndoBar will determine if tranlucent mode(4.4) is using and adjust its position.


  • UndoBar provides 3 default styles. You can use them for different purposes like undo,refresh, or just use it as replacement of toasts. For example, you can use retry style in this way.

    new UndoBarController.UndoBar(this).message(loader.getException().getMessage()).style(UndoBarController.RETRYSTYLE).listener(this).show();
  • UndoBar will switch to KitKat L&F in API-19 target and Material design in API20+.

  • You can set theme in your appliation to change the look and feel. For example, you can use following lines in your style.xml to always use material style UndoBar.

    <style name="MaterialTheme" parent="android:Theme.Light">
        <item name="undoBarStyle">@style/UndoBarMaterialStyle</item>
  • You can change undobar style completely by define your own style

        <style name="UndoBarClassicStyle">
            <item name="containerStyle">@style/UndoBarClassic</item>
            <item name="messageStyle">@style/UndoBarMessageClassic</item>
            <item name="buttonStyle">@style/UndoBarButtonClassic</item>
            <item name="dividerStyle">@style/UndoBarDividerClassic</item>
            <item name="inAnimation">@anim/undobar_classic_in_anim</item>
            <item name="outAnimation">@anim/undobar_classic_out_anim</item>

Advanced usage

  • Using UndoBarController.AdvancedUndoListener if you need to get notification when UndoBar was cleared or hidden.
  • UndoBar is designed to dynamically add to activity viewgroup, so you need to handle screen-rotation by your self. Check this example to see more.
