Android :: TextViews Parametrization / Binding To Model Possible?

Feb 12, 2010

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)

Nov 5, 2010

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...

Mar 17, 2010

I have a class that extends, 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?

Sep 17, 2010

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?

Android :: View That Contains Several TextViews An ImageView And A Button

Jun 9, 2010

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

Android : TextViews Don't Fit Into The LinearLayout - They Are Together Wider Than 320px

Feb 18, 2010

I have a horizontal LinearLayout, inside which I have 2 TextViews. Let's say that the LinearLayout's width is 320px. If the TextViews don't fit into the LinearLayout (they are together wider than 320px), I want to somehow achieve this:

The second TextView is fully displayed and is at the right edge of the LinearLayout
The first TextView is only shown partially, only first x characters are visible

What I mean:

[TextView1|TextView2_____________] // this is normal

[VeryVeryL...|VeryVeryLongTextView2] // VeryVeryLongTextView1 is not fully visible

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.

Android :: Should I Use Local Service Binding?

Oct 5, 2009

I am very new beginner, and I am designing a small application as below.

- After a user starts the application, he/she can click the start button to start a background task. (e.g. retrieving the news headlines periodically, then do something...)

- Even after the user quits the application, the background task still running.

- To stop the background task, the user needs to run the application again, and clicks the stop button to stop the background task.

In the above scenario, what API should I use ? (Local Service Binding ? Remote Service Binding ? Handler ?)

Android :: Binding Service To Activity

Dec 16, 2009

I am working on an android application, where the activity binds to a local service to perform certain tasks.Now I am binding the service in the OnCreate method of the Activity, after which the activity has to use the service object to invoke the functionality defined in the servicein the OnStart method. The problem here is that once a call "bindservice" has been made, we might not get the serviceobject immediately, so my service object would be null till that time. So i cannot invoke the service functions.So is there a way to determine in the activity that the service has been bound and the service object is valid and could be used now. For reference i'm attaching a code snippet for the same.

Android :: How Binding To Services Works

Jul 2, 2010

I'm a little confused on how binding to services works. I understand using Context.startService() starts the service and that bindService doesn't call onStartCommand. But my understanding is that if I use startService, I have to explicitly stop the service. But I want the service to die if there are no more activities bound to it.My problem is that calling bindService never calls onServiceConnected(), so my Service binder object is null. Does the service have to be explicitly started in order to bind to it? If so, how does it know to terminate when nothing is binding to it anymore, and how do I know if it's started so I can know to use the bound object?

Android :: Binding From SQLite To Gallery ?

Oct 19, 2010

I am just starting out with Android and I am attempting my first test app, but I am a bit stuck.

I have an SQLite database and a user is selecting a picture and a reference to this a long with a short description is getting stored in the database. This is all working fine, now I want to bind the images from to database to a gallery, but I am a bit confused how I do this.

My layout xml is as follows:


I want the gallery with a button below

My on create function I have the following:


I am using the notepad tutorial as an example and my class extends ListActivity.

When I run it I get the error

Your content must have a ListView whose id attribute is ''

I'm assuming I am using the wrong type of binding, but I can't seem to find anywhere that tells me how to bind from an sqlite DB to a gallery.

I also want to add a reference to the rowId in the gallery so when the image is clicked it will open the relevant page (so it can show the message)

Android :: Dialog With Multi-column Selectable Textviews

May 3, 2010

I'm trying to create a dialog with multi-column selectable textviews, please take a look to the uploaded picture

In other words it should be looked like a standard ListView dialog but with two or more columns separated with a line.

I've tried using a GridView for this, but I haven't found a way to add separators between items.

I also tried to play with padding&bg color (result on the picture [url]) but I couldn't avoid the table bounds and problems with selection.

Is there a way to create such dialog and how?

Android :: TextView Gravity - Implementation Of ViewGroup With Some TextViews In It?

Has anyone tried to write his own implementation of ViewGroup with some TextViews in it? I have a problem, that TextViews in such an implementation don't respect gravity attribute (TextView.setGravity(Gravity.CENTER);) and text is positioned in the top left corner.

If enyone is interested, I just overwrote method onMeasure() (for all my TextViews) and changed call from super.onMeasure() to setMeasuredDimension(int, int) and gravity started to work normally.

Basically, in my custom layout I use the following class to display text:
