Ultra Pull To Refresh

It's a replacement for the deprecated pull to refresh solution. It can contain any view you want.

It's easy to use and more powerful than SwipeRefreshLayout.

It's well designed, you can customize the UI effect you want as easy as adding a headview to ListView.

Support API LEVEL >= 8, all snapshots are taken from Genymotion, 2.3.7.

Config in xml

<in.srain.cube.views.ptr.PtrFrameLayout
    android:id="@+id/store_house_ptr_frame"
    xmlns:cube_ptr="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    cube_ptr:ptr_resistance="1.7"
    cube_ptr:ptr_ratio_of_header_height_to_refresh="1.2"
    cube_ptr:ptr_duration_to_close="300"
    cube_ptr:ptr_duration_to_close_header="2000"
    cube_ptr:ptr_keep_header_when_refresh="true"
    cube_ptr:ptr_pull_to_fresh="false" >

    <LinearLayout
        android:id="@+id/store_house_ptr_image_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/cube_mints_333333"
        android:clickable="true"
        android:padding="10dp">

        <in.srain.cube.image.CubeImageView
            android:id="@+id/store_house_ptr_image"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>

</in.srain.cube.views.ptr.PtrFrameLayout>

Or config in java code

// the following are default settings
mPtrFrame.setResistance(1.7f);
mPtrFrame.setRatioOfHeaderHeightToRefresh(1.2f);
mPtrFrame.setDurationToClose(200);
mPtrFrame.setDurationToCloseHeader(1000);
// default is false
mPtrFrame.setPullToRefresh(false);
// default is true
mPtrFrame.setKeepHeaderWhenRefresh(true);

StoreHouse Style

Config using string:

// header
final StoreHouseHeader header = new StoreHouseHeader(getContext());
header.setPadding(0, LocalDisplay.dp2px(15), 0, 0);

/**
 * using a string, support: A-Z 0-9 - .
 * you can add more letters by {@link in.srain.cube.views.ptr.header.StoreHousePath#addChar}
 */
header.initWithString('Alibaba');

Config using string array from xml:

header.initWithStringArray(R.array.storehouse);

And in res/values/arrays.xml:

<resources>
    <string-array name="storehouse">
        <item>0,35,12,42,</item>
        <item>12,42,24,35,</item>
        <item>24,35,12,28,</item>
        <item>0,35,12,28,</item>
        <item>0,21,12,28,</item>
        <item>12,28,24,21,</item>
        <item>24,35,24,21,</item>
        <item>24,21,12,14,</item>
        <item>0,21,12,14,</item>
        <item>0,21,0,7,</item>
        <item>12,14,0,7,</item>
        <item>12,14,24,7,</item>
        <item>24,7,12,0,</item>
        <item>0,7,12,0,</item>
    </string-array>
</resources>

Process Refresh

There is a PtrHandler, by which you can refresh the data.

public interface PtrHandler {

    /**
     * Check can do refresh or not. For example the content is empty or the first child is in view.
     * <p/>
     * {@link in.srain.cube.views.ptr.PtrDefaultHandler#checkContentCanBePulledDown}
     */
    public boolean checkCanDoRefresh(final PtrFrameLayout frame, final View content, final View header);

    /**
     * When refresh begin
     *
     * @param frame
     */
    public void onRefreshBegin(final PtrFrameLayout frame);
}

An example:

ptrFrame.setPtrHandler(new PtrHandler() {
    @Override
    public void onRefreshBegin(PtrFrameLayout frame) {
        frame.postDelayed(new Runnable() {
            @Override
            public void run() {
                ptrFrame.refreshComplete();
            }
        }, 1800);
    }

    @Override
    public boolean checkCanDoRefresh(PtrFrameLayout frame, View content, View header) {
        return PtrDefaultHandler.checkContentCanBePulledDown(frame, content, header);
    }
});

Customize

You can add a PtrUIHandler to PtrFrameLayout to implement any UI effect you want.

public interface PtrUIHandler {

    /**
     * When the content view has reached top and refresh has been completed, view will be reset.
     *
     * @param frame
     */
    public void onUIReset(PtrFrameLayout frame);

    /**
     * prepare for loading
     *
     * @param frame
     */
    public void onUIRefreshPrepare(PtrFrameLayout frame);

    /**
     * perform refreshing UI
     */
    public void onUIRefreshBegin(PtrFrameLayout frame);

    /**
     * perform UI after refresh
     */
    public void onUIRefreshComplete(PtrFrameLayout frame);

    public void onUIPositionChange(PtrFrameLayout frame, boolean isUnderTouch, byte status, int oldPosition, int currentPosition, float oldPercent, float currentPercent);
}
