This library let you define a front and back layout, which get added to the FlipIconChecker. The view flips with a animation to the other side when it is checked and a custom view scale in. This library makes it easy to make flipping views like Google in the Holo and Material Gmail app or the material sms app. Compatible with api level 15+.

compile 'org.tmcrafz.flipiconchecker:flipiconchecker:0.8.3'

By default, when you dont specify an extra atrribute, the front layout contains a red colored shape and a gray back, with a white check icon "scaling" in:

Front:	Back:

<org.tmcrafz.flipiconchecker.FlipIconChecker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

You can specify your own custom layouts for the front, back and the layout which "scale" in when the view get checked. When you use custom layouts it is best you set "layout_width" and "layout_height" of the FlipIconChecker to "wrap_content". You get the best results when all custom layouts have the same size. The checkView layout, which you specify get scaled from 0% to 80% of his full size. With the "duration" attribute you can set a custom duration for the animation from one side to the other side. By default one flip takes 200ms:

<org.tmcrafz.flipiconchecker.FlipIconChecker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:frontView="@layout/custom_front_layout"
        app:backView="@layout/custom_back_layout"
        app:checkView="@layout/custom_check_layout"
        app:duration="250" />

Instead of custom layouts you can specify custom drawables. If you have specified a custom drawable and a custom layout for the same purpose (e.g. front) the layout is ignored. So only specify a custom drawable or a custom layout for the same purpose:

<org.tmcrafz.flipiconchecker.FlipIconChecker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:frontSrc="@drawable/red_shape"
        app:backSrc="@drawable/blue_shape"
        app:checkSrc="@drawable/ic_camera" />

Get the state of the FlipIconChecker:

flipIconChecker.isChecked();

You can add a click listener to the flipIconChecker:

flipIconChecker.setOnFlipIconCheckerClickedListener(
                new FlipIconChecker.OnFlipIconCheckerClickedListener() {
      @Override
      public void onFlipIconCheckerClicked() {
                // Do something
      }
});
