Android : Create A Bunch Of Textviews Programmatically?
Apr 17, 2010
I need some help with the following scenario, as I am so used to make all of my layouts with XML, but now I have a situation where that won't work.
I am working on the second version of my app that delivers news, in the comments section I used to use a listview to display user comments, but it doesn't work that great for comments that could be anywhere from 5 to 500+ characters long. So I want to create a whole bunch of TextViews in a scrollview and stack them below each other.
My best guess was this, although it is definitely wrong because it only shows one comment. I assume I have to use some kind of LayoutParams and so I've looked into it but am still not sure how exactly to use them.

I want to create an XML file to Store my Application Settings into. ( I can't use SharedPrefs because i want that Settings file later to be accessed by Some other Code.)
I can easily create an XML with java's code and store it in File too. but in Android I can create xml with the same java code but can't save it into the file coz they have removed the package javax.xml.transform from SDK.
I am Attaching the Java code here...

I want to launch an Activity with a webView as its content from current Activity. This new activity needs to be transparent and webview should be in the center. I looked around the web but only solutions I found were using style xmls. I want to do it using pure code i.e. no xml declarations. if anybody has come across this then please shed some light.

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.
Here's what I got:
This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):
ArrayList<String> spinnerArray = new ArrayList<String>();
This is code ...
Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ).
It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it.

In ApiDemo, there is a progressBar demo. It creates a horizontal progress bar with a xml.
<ProgressBar android:id="@+id/progress_horizontal" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" />
But how to create one programmatically? If just new ProgressBar(fContext), it is Default ProgressBar style.

Does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets?
What are the pros/cons of both approaches?
I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.

I have an xml layout that will display a grid made up of textviews within tablerows. The textview names are cell00, cell01, etc. At runtime, my program will determine which cell needs to be changed.
Is there a way get format a name so that it can be passed to the findViewById method at runtime? For example, if cell00 is needed, how can I generate the parm in this code?
TextView currcell = (TextView) findViewById(R.id.cell00)
Something like "cell"+00 doesn't compile because the findViewById method doesn't accept a String type. I don't want have every textview name in the grid hardcoded in the program - there must be a better way.

When I go to the gallery and select a photo and hit the share button, I get a bunch of choices that I never use and probably never will. I have to scroll all the way to the bottom to get to the twitdroid. Does anyone know how to remove the "share" selections like peep, or picasa, or facebook. If you know a setting that I seem to be missing, please share.

Frustrating & embarrassing!
Suspected bluetooth getting "pressed" when stuffed in my purse - bur can't replicate (make it happen on purpose.)
Have tried changing settings - no luck.
Something about putting Droid & bluetooth in purse makes 6 redials +++ happen.

I am simply trying to create a layout where there are multiple TextViews (and ultimately an EditText) stacked vertically in the activity. However, the only thing displayed is my top title bar and the first TextView (with the "Name" text). Why won't anything else show up? Here is my code...

I have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method. My problem is that whenever the dialog is displayed, then dismissed, and displayed again, the Editable TextViews are still populated with the information that was displayed previously. What is the common way to clear these text fields?

I am new to both Android and Stack Overflow. I have started developing and Android App and I am wondering two things:1) Is it possible to parametrize a TextView? Lets say I want to render a text message which states something like: "The user age is 38". Lets suppose that the user age is the result of an algorithm. Using some typical i18n framework I would write in my i18n file something like "The user age is {0}". Then at run time I would populate parameters accordingly. I haven't been able to figure out how to do this or similar approach in Android. 2) Let's suppose I have a complex object with many fields. Eg: PersonModel which has id, name, age, country, favorite video game, whatever. If I want to render all this information into a single layout in one of my activities the only way I have found is getting all needed TextViews by id and then populate them one by one through code. I was wondering if there is some mapping / binding mechanism in which I can execute something like: render(myPerson, myView) and that automatically through reflection each of the model properties get mapped into each of the TextViews. If someone has ever worked with SpringMVC, Im looking for something similar to their mechanism to map domain objects / models to views (e.g. spring:forms)

I have a string called CurrentString and is in the form of something like this "Fruit: they taste good". I would like to split up the CurrentString using the : as the delimiter. So that way the word "Fruit" will be split into its own string and "they taste good" will be another string.and then I would simply like to use SetText and 2 different textviews to display that string. What would be the best way to approach this?

I' have a view that contains several textViews an ImageView and a Button . Because on small screen devices (or in landscape mode on big ones ) not all are visible I use a Scroll as the parent of the whole hierarchy to allow the user to view all the information. The things are suck that the button must be at the buttom of the view . However on big screen device , where it remains enough space at the buttom , the button is put immediatelly below the last textview,and seems to occupy all the remaining space (resulting in an unnactractive view) . Trying to use android:allignParentButtom ="true" not only that it has no effect but it puts the button at top of the screen . Has anyone any ideea how could I accomplish what I described ?
Here's the xml
