PagedHeadListView Android Library

[](http://android-arsenal.com/details/1/816)

Details

If you are looking for a listview with a paged header this is the dependency you are looking for. With PagedHeadListView you will be able to set your own fragments as new pages for the header, and a brand new indicator will be added automatically. You can play with all the custom attributes provided with the library to set indicator colors and position, ViewPager drag animation, and touch behaviour for the header view. PagedHeadListView supports API 11 - Android SDK 3.0 (HoneyComb) as minimum.

This lib brings a custom ListView class called PagedHeadListView to the final user. Use it to integrate the component in your own Android application. You will not need to create your own code with FragmentStatePagerAdapter or ViewPager by yourself for creating this cool user experience, as the library does the boring work for you.

Custom Attributes

This android library allows you to customize the following properties. Feel free to combine them to create your cool user interfaces:

• pagedheadlistview:headerHeight: Dimen resources allowed.
• pagedheadlistview:disableVerticalTouchOnHeader: Set it to true if you want the header to not be affected by verticall ListView scrolling.
• pagedheadlistview:indicatorBgColor: Color resource for indicator background.
• pagedheadlistview:indicatorColor: Color resource for indicator view.
• pagedheadlistview:indicatorType: Type for the indicator. Types allowed are: topAligned, bottomAligned, and none. If you set the value to none, no indicator will be included.
• pagedheadlistview:pageTransformer: You can set it to depth, zoomout, rotate, scale, flip, or accordion for using one of the stated ViewPager drag animations.

You can cutomize your own pageTransformer by extending ViewPager.PageTransformer native Android class and by adding it to the PagedHeadListView using the following method:

mPagedHeadListView.setHeaderPageTransformer(boolean reverseDrawingOrder, ViewPager.PageTransformer customPageTransformer);

Usage

In order to make it work, you will need to use PagedHeadListView class into your Android code. Please, don't forget to add the aditional xmlns:pagedheadlistview="http://schemas.android.com/apk/res-auto" namespace to it.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:pagedheadlistview="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.jorgecastilloprz.pagedheadlistview.PagedHeadListView
        android:id="@+id/pagedHeadListView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        pagedheadlistview:headerHeight="@dimen/header_height"
        pagedheadlistview:indicatorType="bottomAligned"
        pagedheadlistview:disableVerticalTouchOnHeader="true"
        pagedheadlistview:indicatorBgColor="@color/material_green"
        pagedheadlistview:indicatorColor="@color/material_light_green" />

</RelativeLayout>

In your java code, use PagedHeadListView like this:

mPagedHeadList = (PagedHeadListView) rootView.findViewById(R.id.pagedHeadListView);

mPagedHeadList.addFragmentToHeader(new FirstHeaderFragment());
mPagedHeadList.addFragmentToHeader(new SecondHeaderFragment());
mPagedHeadList.addFragmentToHeader(new ThirdHeaderFragment());
mPagedHeadList.addFragmentToHeader(new FourthHeaderFragment());
mPagedHeadList.addFragmentToHeader(new FifthHeaderFragment());

mPagedHeadList.setHeaderOffScreenPageLimit(4);
mPagedHeadList.setHeaderPageTransformer(PageTransformerTypes.FLIP);

ArrayList<String> mockItemList = new ArrayList<String>();

for (int i = 0; i < 50; i++)
    mockItemList.add(getResources().getString(R.string.mock_item) + " " + (i+1));

MockListAdapter mockListAdapter = new MockListAdapter(getActivity(), R.layout.mock_list_item, mockItemList);
mPagedHeadList.setAdapter(mockListAdapter);

For being able to listen to header page change events, use setOnHeaderPageChangeListener which needs a ViewPager.OnPageChangeListener item as an argument.

Following methods are avaiable to setup the pager programatically:

//Types vaiable: DEPTH, ZOOMOUT, ROTATE, SCALE, FLIP, ACCORDION.
mPagedHeadListView.setHeaderPageTransformer(PageTransformerTypes pageTransformerType);

//This is a mapping for normal setPageTransformer from Android support ViewPager.
mPagedHeadListView.setHeaderPageTransformer(boolean reverseDrawingOrder, ViewPager.PageTransformer customPageTransformer);

//Dynamic mode to set header's view height. (Always in pixels)
mPagedHeadListView.setHeaderHeight(500);
mPagedHeadListView.setHeaderHeight(getResources().getDimensionPixelSize(R.dimen.header_height_test));

//For the user to be able to listen for header ViewPager events.
mPagedHeadListView.setOnHeaderPageChangeListener(ViewPager.OnPageChangeListener onPageChangeListener);

mPagedHeadListView.setHeaderOffScreenPageLimit(int offScreenPageLimit);

mPagedHeadListView.setIndicatorBgColor(int indicatorBgColor);
mPagedHeadListView.setIndicatorColor(int indicatorColor);

//If you want to disable vertical touch on header programatically.
mPagedHeadListView.disableVerticalTouchOnHeader();

mPagedHeadList.setIndicatorBgColor(getResources().getColor(R.color.material_green));
mPagedHeadList.setIndicatorColor(getResources().getColor(R.color.material_light_green));

Import PagedHeadListView dependency

Add the next code to your build.gradle project dependencies:

dependencies {
    compile 'com.github.jorgecastilloprz:pagedheadlistview:1.0.0@aar'
}

Set the mavenCentral repo into the external build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

If you are using Maven, use the following code:

<dependency>
  <groupId>com.github.jorgecastilloprz</groupId>
  <artifactId>pagedheadlistview</artifactId>
  <version>1.0.0</version>
  <type>aar</type>
</dependency>

TODO - AT WORK

• Give the users the possibility to extend AbstractPagedHeadIndicator class to develop their own indicators. A new setter will be added for it when i get sure that it is fully supported.
