I am creating a custom indicator, when the user dropped the custom indicator into their chart, I want the Bollinger Band be shown on the chart too. Is there a way to achieve that within the custom indicator?
only if you create three extra buffers and fill them in with Bands values. EA can show all employed indicators after backtesting is done, but in real time - no. As far as i know

I have used Charts library to make my chart. It really has ton of options, but I have been struggling to implement background for grid. I want to have gradient background, but just for grid part. I have done this by putting my view behind the chart view. I have printed _viewPortHandler.contentRect, and from there i positioned my view. Now, while this works, it is not most ideal solution. I would like to somehow at runtime have option to get gridview size, but since _viewPortHandler is internal, I see no option to do this:
Is there any better way to do this?
I am looking to improve my app's signup and login form from standard text boxes to using table rows (or something similar).
I am pretty much inspired by the forms which SnapChat have created, which you can see below...
I'm trying to figure out how they accomplished this, and am thinking it must be a table view with 3 cells (Static?), and the text below is part of the footer of that selection of cells.
How is one able to then capture data into it directly?
Am I right in maybe assuming that each cell is 'custom' with a text field in each one (with placeholder text) with a no-borders style on the text field?
Or has this been achieved via some other way?
Keen to hear your thoughts. Thanks!
You absolutely could do that with a table view. But I don't think this one is. Notice the divider lines start at the far left rather than at 15 pixels in (with the text). The separator lines are also two pixels tall rather than one. So I'd say it's a safe bet that it's just a simple view with 1 pixel tall UIView's for lines.
i have a listfield where i am adding the contents in a horizontal field manager first and then adding the manager to a vertical manager. Visually:
----Image ---Text ----Image
---Text ----Image
---Image
How can i achieve this using a horizontal field manager
You might want to clear up the question a bit, but I'll try to answer what I think you're asking. ListFields don't support (natively) drawing a Manager as its row -- or a Field for that matter. What you'll need to do is in your ListFieldCallback's drawListRow() method, emulate this by doing the painting the way you want it to look. It would end up being measurements with bitmap.getWidth() and font.getAdvance(text) to figure out where to draw the images and text, but it should be a simple enough process.
Can anybody help me how to arrange StandardTitlebar elements,for example I want battery indicator to be leftmost and network indicator rightmost,and clock to be center of status bar.
It's not possible. According to StandardTitlebar API,
You cannot change the order of components in the standard title bar. The positions are fixed to the order listed above. The order in which you call the add functions has no bearing on the position or order of these components.
So you have to stick to the order specified in API.
Only option for you to position fields is to create your own custom manager and add it to MainScreen using setTitle(). But then again I am not sure how will you create Battery, Clock and network indicator. BB doesn't provide any API for these fields.

The above is a link basically showing the form fill view of the numbers app on the iPad. Any idea as to how to achieve such a functionality which sort of looks like our vanilla tabs on Chrome?
You could do it with just buttons set to Custom type and using an image for the background. Then when they are clicked, bring the specific UIView to the front.
To create the tabs from a single image use UIImage's stretchableImageWithLeftCapWidth: topCapHeight:

This will let you dynamically set the image's width in a way that will use the middle of it to fill the new area rather than stretching (and warping) the outer edges.
I would have implemented this with simple UIButtons. All you need to do is to style them (pngs or whatever), and track which one is the current.
