FlippableStackView
An Android library introducing a stack of Views with the first item being flippable.
Views
inside the stack remain the aspect ratio of the FlippableStackView
.
Library in action
Usage
For a working implementation of this library see the sample/
folder.
-
Include the view inside your layout xml
<com.bartoszlipinski.flippablestackview.FlippableStackView android:id="@+id/stack" android:layout_width="match_parent" android:layout_height="match_parent" />
-
FlippableStackView
is based on the specificPageTransformer
used with theViewPager
. Therefore to fill theView
you can use just a typical implementation of aPagerAdapter
. In youronCreate
method (oronCreateView
for a fragment), setup all the parameters of theFlippableStackView
.FlippableStackView stack = (FlippableStackView) findViewById(R.id.stack); stack.initStack(2); stack.setAdapter(mStackAdapter); //assuming mStackAdapter contains your initialized adapter
Important Note: The current implementation of the library will display the elements from the Adapter
in the reverse order. In other words: view at position 0 of your adapter will be displayed at the bottom of the stack and view at position adapter.getCount()-1
will be visible first (available for the first flip).
Customization
The FlippableStackView
is highly customizable to provide you with just the visual effect you really wanted.
There are three methods that allows for initialization of the stack:
-
First one sets up the stack in the default way (scale-wise and orientation-wise):
public void initStack(int numberOfStacked)
-
The second one sets up the stack in the default way (scale-wise) but let's you choose the orientation of it:
public void initStack(int numberOfStacked, StackPageTransformer.Orientation orientation)
-
And the last one... a bit more advanced (lets you customize all the scale-related, orientation-related and alignment-related parameters):
public void initStack(int numberOfStacked, StackPageTransformer.Orientation orientation, float currentPageScale, float topStackedScale, float overlapFactor, StackPageTransformer.Gravity gravity)
Be sure to read about all the parameters in Javadoc
before using the last one.
Including In Your Project
You can grab the library via Maven Central. Just add a proper dependency inside your build.gradle
. Like this:
dependencies {
compile 'com.bartoszlipinski.flippablestackview:library:1.2.1'
}
