A GridView with the ability to have multiple headers

HeaderGridView

Introduction

This is an updated version of GridView which allows for Headers. The Headers themselves are not part of the adapter / data source. This means that the headers only are not being recycled.

Setup

To use HeaderGridView in your projects, simply add this project to your workspace then add it as a library project to your current project.

Usage

HeaderGridView can be added as a custom view to any layout.

instead of <GridView /> use…

    <com.origamilabs.library.views.HeaderGridView />

then simply add header views via

    // same methods as ListView
    addHeaderView(View v, Object data, boolean isSelectable);
    addHeaderView(View v);

Tests

None.

TODO:

• implement Footer support. should be simple
• develop tests

headergridview's Issues

Headerview does not travel with Gridview

When I scroll a gridview the header moves half of the screen only and half of the header is seen in the screen. It doesn't working like listview's header view.

Is it possible to set header view center horizontal?

I used this control, is a good solution to add header view to gridview. But how to set header view center horizontal?

addFooterView()

I'd appreciate if it you'd add addFooterView, since this is much more useful for me than a HeaderView.

it's fixed headerview not like the listview addheaderview()?

it's fixed headerview not like the listview addHeaderView() ? how to solve it ?

Remove headerView issue

i've added HeaderGridView to my project successfully but the problem is i cannot remove headerview or update it. because the below if statement (info.view == v) is always false :

private boolean removeFixedViewInfo(View v, ArrayList<FixedViewInfo> where) {
    int len = where.size();
    int count = 0;
    for (int i = 0; i < len; ++i) {
        FixedViewInfo info = where.get(i);
        if (info.view == v) {
            this.setPadding(this.getPaddingLeft(), getPaddingTop()-v.getMeasuredHeight(), this.getPaddingRight(), this.getPaddingBottom());
            where.remove(i);
            count++;
            break;
        }
    }

    return count > 0;
}

can you help me with this and explain me why this happens? v is a global View which i've used to add header view before.

header can't be clicked

there's some button,after i set onclicklistener ,it doesn't work

Header Scroll Issues

When scrolling down by way of DPad selection, the header moves up, but the space the header previously occupied continues to cut off the grid. The effect is that the header area becomes white, and grid items scroll under the white area.

It's can't use it

At HeaderGridView.java line 96.
"v.measure(MeasureSpec.makeMeasureSpec(mDisplayWidth, MeasureSpec.AT_MOST), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));" In setupView(View view).
It's always throw nullPointException.
why????
