Installation

? Just download the package from here and add it to your project classpath, or just use the maven repo:

Gradle:

'com.ramotion.foldingcell:folding-cell:1.2.1'

SBT:

libraryDependencies += "com.ramotion.foldingcell" % "folding-cell" % "1.2.1"

Maven:

<dependency>  <groupId>com.ramotion.foldingcell</groupId>  <artifactId>folding-cell</artifactId>  <version>1.2.1</version> </dependency>

Basic usage

Add com.ramotion.foldingcell.FoldingCell to your layout ?

... <com.ramotion.foldingcell.FoldingCell
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/folding_cell"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"> ? </com.ramotion.foldingcell.FoldingCell> ...

? 2. Add exactly two child elements to your cell. The first child ( content view) always represents the unfolded state layout and the second child ( title view) represents folded state layout. Of course, those layouts can contain any number of child elements and they can be any complexity, but to work correctly, there are some limitations: content view height must be at least 2x times greater than title view height, and the height of each of those layouts must be set to android:layout_height="wrap_content". If you want to set exact height in dp , you can set height for child elements in your own layout inside content view or title view. Also, you need to hide your content view layout using android:visibility="gone". ?

... <com.ramotion.foldingcell.FoldingCell
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/folding_cell"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"> ?

<FrameLayout

 android:id="@+id/cell_content_view"

 android:layout_width="match_parent"

 android:layout_height="wrap_content"

 android:background="@android:color/holo_green_dark"

 android:visibility="gone">

 <TextView

  android:layout_width="match_parent"

  android:layout_height="250dp" />

</FrameLayout> ?

<FrameLayout

 android:id="@+id/cell_title_view"

 android:layout_width="match_parent"

 android:layout_height="wrap_content">

 <TextView

  android:layout_width="match_parent"

  android:layout_height="100dp"

  android:background="@android:color/holo_blue_dark" />

</FrameLayout> ? </com.ramotion.foldingcell.FoldingCell> ...

? 3. Almost done! Two steps remain! For correct animation, you need to set up two properties on the root element(s) of your Folding Cell: ?

android:clipChildren="false" android:clipToPadding="false"

? 4. Final step! Add onClickListener to your Folding Cell in MainActivity.java to toggle animation: ?

@Override protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);
 ?
  // get our folding cell
  final FoldingCell fc = (FoldingCell) findViewById(R.id.folding_cell);
 ?
  // attach click listener to folding cell
  fc.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

 fc.toggle(false);

}

  
}
);
 
}

? 5. Extra step - customizing cell settings. For now, there are three main parameters - animation time, back side color and additional flips count. If first two do not cause questions, the third requires an some explanation. It is count of flips to be executed after first(main) flip. Default value is 0(auto choose). Also there is a fourth, additional parameter - camera height, it controls level(depth) of 3d effect. There are two ways to change cell settings: From xml layout file with res-auto namespace xmlns:folding-cell="http://schemas.android.com/apk/res-auto":

folding-cell:animationDuration="1000" folding-cell:backSideColor="@color/bgBackSideColor" folding-cell:additionalFlipsCount="2" folding-cell:cameraHeight="30"

Or from code:

// get our folding cell final FoldingCell fc = (FoldingCell) findViewById(R.id.folding_cell);
 // set custom parameters fc.initialize(1000, Color.DKGRAY, 2);
 // or with camera height parameter fc.initialize(30, 1000, Color.DKGRAY, 2);
