963721 - Handle clicks on views in dynamic panels

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: Awesomescreen, defect)

Description

[:Margaret Leibovic]

Once bug 959777 lands, we should look into how we'll handle clicks (and long clicks) on items in dynamic panels.

We've talked about storing URLs with dataset items, then launching an intent with this URL when the user clicks on an item. I think this would be a good approach to start with.

This would be a good hack week task!

I can take this.

Looking good. Still needs a round of tweaks.

Don't we already have something in GeckoAppShell for triggering intents from URLs? Just make sure you're not duplicating code here.

INTENT -> OPEN_WITH_INTENT for clarity?

I'd go with:

if (cursor == null || !cursor.moveToPosition(position)) {
    throw new IllegalStateException("Couldn't move cursor to position " + position);
}

The cursors used in PanelListView use the HomeItems schema. So this should actually be HomeItems.URL instead.

nit: add an empty line above this.

Fixed up, one point of discussion:

The only one in GeckoAppShell that would work seems much less readable to me, and is complicated (which could be more prone to breaking):

> Intent intent = GeckoAppShell.getOpenURIIntent(this, url, "", Intent.ACTION_VIEW, null);

It could be still more preferable to add a new static method though?

Hmmm, this constructor is getting a bit too loaded but I can live with that.
