I am building an Android app for a forum and the API they have created returns 'bbCode' for posts and private messages. Things like [b]bold text here[/b] for bold text and [spoiler]hidden text here[/spoiler] for hidden text which is then revealed by clicking a button of some kind. I am building a parser that will create a mapping between raw text some text to be hidden and type of component PostComponent.SPOILER for example.
How would I go about inflating this parsed and categorised data into multiple Android views dynamically, and then proceed to merge them into one view which will be displayed in a list (to display a list of posts like you see in a forum)?
I can think of a few hacks to get this done (like creating a layout for each post component and having each of them in a non-scrollable listview stacked on top of one another), but I can't quite think of a nice efficient solution.

My app displays a map with some type of map marker (within a Fragment) and if I click on one of these markers, a popup comes up to show some additional information about this marker. Currently I'm using a normal AlertDialog for that but I might replace it with a DialogFragment in the future.
Inside the dialog there's a RecyclerView that is filled with multiple values. If I click on one of the rows, I want my app to open a "fold-out" underneath it (the other rows should move down) that displays even more information about that row. Clicking on the row again should close that "fold-out".
Similar to what the FoldingCell library does but I want to add to the original row (instead of replacing it) and also don't need the fancy animation.
Like this:
Is "fold-out" the right word for it? I'm pretty sure I saw a similar question here on Stackoverflow (might have been for iOS) a while back but I've not been able to find it again yet. I know how to do the whole onClick thing for the map and the RecyclerView but how do I accomplish the "fold-out" part (create design in xml, then load via Java class)?
I want to create a sort of inline list of clickable text blocks in Android Studio. Below is the closest image I could find to the effect I would like. How would I achieve such an effect?
The information shown will be just a string, however clicking on this will take the user to another activity. It would be good if the text blocks also had a background, by the looks of it this app uses an image as the background, which should be fairly easy to set if the list is made from text views. I just don't know how to make a list with variable length inline objects.

What I was looking for was specifically a horiztonal, wrapping, inline list.
I'm new to Java and Android. I have been trying for the past week to make an app for my phone. The app consists of 4 pages, which are diagrammed below:
Page 1: Contains a picture taking up the size of the screen. If I click on the picture it needs to go to "page 2".
Page 2: Consists of an icon on the left (say the flag for instance) followed by a text field (eg. USA). When "USA" strip is clicked it needs to go to page 3.
Page 3: Consists of text, picture and then more text from a string. This page needs to correspond to the strip clicked on in page 2 ("USA" in this example). There are also two buttons at the bottom of "page 3" and "page 4" which when pressed need to go to the corresponding page numbers.
Page 4: This page is displayed if the "More" button is pressed on "page 3".
I would like this phone to work on a minimum Android 2.2 or 2.3. All logos, pictures and string texts need to be locally available (resources folder) and not website based. I have tried all sorts of combinations of ListView's and buttons with OnClickListener's as well as toast screens. My limited knowledge of programming is frustrating.
My question is if there is a template around which will help me out with this app? Or if there are any web resources.
In Android, individual "pages" or "screens" can be implemented as Activitys. You need to extend the Activity class and add the components that you wish to display. Most of the layout can be done in an XML file. I strongly suggest that you google for a tutorial that illustrates the basics of Android programming. From there, you can start by creating an app with two pages. And then just keep adding a little bit at a time until you get the complete app that you want.
There some easy ways to do this. If you want to be backwards compatible to SDK 8 you can do this in two ways. You can use Fragments or Activities for each layout. If you implement fragments, I suggest reading http://developer.android.com/guide/components/fragments.html inside there you will about using the FragmentActivity instead of the Activity. Read this link http://developer.android.com/tools/extras/support-library.html as it will have the needed libraries to implement the Fragments in older versions of the SDK. It does looks like you looking for some navigation buttons that reside on the bottom of the layout. In order to fully implement a layout that has this view on the bottom of the screen in SDK 8, you will need to create your own View and place it on the bottom of the screen. RelativeLayout and alignParentBottom = "true" will accomplish this. There is also a way to do this using a ViewPager which will also work in the backwards compatibility requirements you have. I am sorry the amount of information I am throwing at you but I really would recommend looking into other questions posted by users on this topic. How to navigate to another page in android? for example. Good luck and everything you are looking for is able to be learned through a Google search. Maybe not all at once.
To clarify this - what I want to do is:
a) to open a http request to obtain some XML
b) parse that XML
c) given the (fixed) number of elements, put them with a bucle in the layout.
What I am missing is the last part. An example is 'twicca' or just the official Twitter application, that fills the layout with tweets. I want to do something like that. How should I proceed?
My first thought was creating a fixed number of TextView and change those TextView (TextView1, TextView2, ...) with the content I wish. But that doesn't sound very professional...
The standard way to do this in Android is with a ListView (link to developer guide), which automatically creates as many items as needed from the data source. Most examples show pulling from a local SQLite database, but after you've loaded your XML items into an array in memory you can use an ArrayAdapter as the data source for the ListView.
I want to be able to add a text-messaging balloon every time the user revives data from a HttpGet, I want it so that it looks nearly identical to the default Android text messaging UI. I'm fine with all the code, I just need a way to create the UI and create another text balloon every time data comes back from a HttpGet request.
Thanks ever so much, for the answering this questions and I'm sure there's an easy way to do it, yet I've found no way by using the 'ole Google.
I am doing something similar for my app am doing the following to achieve it:
You will need a 9-Patch-Image (a stretchable PNG, see here) that represents the bubble. You want to make the part stretchable that does not include the corners of the bubble. You can create the bubbles using an image editor of your choice (I'd recommend a vector graphics editor like Inkscape). Then use the 9-Patch editor included in the Android Developer Tools to transform the PNG image into a 9-Patch PNG.
Create a custom layout file for one bubble. Create a textview inside it, and add your bubble as a background resource. (android:background)
Use an arraylist with a custom adapter to inflate and fill your items.
So far, this will give you identical bubbles as background for all messages.
If you want to get fancy, you can create different bubbles for participants, and use the setBackgroundResource method in your Adapter to set the correct background.
Further, if you wish to align them left or right, like in the message app, you will need to add spacers to the left and right of your TextView in the layout file. I used FrameLayouts with a fixed width. Make sure to set their visibility to GONE.
As with swapping the different bubble colors, just set the visibility of the left/right spacer.
