Android : Clear TextViews Before It Is Displayed?

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?

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)

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 ?

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 :: 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?

Nov 10, 2010

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:

Android : RelativeLayout Displaying Contained TextViews Overlapped

Android : Make TextViews Spannable Causes ListView Performance To Tank

Jun 18, 2010

I've got a list few which I've optimized in every possible way. Performance matches the exchange email client so I'm happy in that respect. It's very fluid regardless of the number of records. The problem is the moment I introduce some conditional formatting of TextViews (think bold for unread, normal for read) the list starts to get choppy when the user flings the list. Is there a better way to tackle this formatting?

Android :: Custom Fonts - Ellipsis On MultiLine TextViews - Glyphs And Glitches?

May 25, 2010

I am required to use custom fonts in my application.

Problem: For ListViews that contain rows with Multi-Line TextViews having ellipsize property set to true, I can see some illegible characters after the ellipsis. Apparently Android pads the String(in TextView) with some characters(ZERO WIDTH NO BREAK-SPACE) unknown to my custom font. Single line TextView seem to work just fine.

What is the best way to hide these characters or remove the padding?
Also, is there any variant of Helvetica font, freely available that would have ZERO WIDTH NO BREAK-SPACE character?

Android :: How To Build Activity - Pause For Few Seconds And Then Repopulate Five TextViews With New Values

Jul 15, 2010

onCreate, MyActivity will display five TextViews. After you touch one of the five TextViews, it will hide three to four TextViews and color one red and one green or just color one green.

I can code everything up to here. But how can I pause for a few seconds and then repopulate the five TextViews with new values, unhide them and make them all white?

I tried a Timer in a new project and can attach the code and make my question less vague.

Here is the main.xml


Here is the


The issue is that the Timer executes resetAndContinue and logs two entries, but it doesn't set the TextView color from green to white and it doesn't log anymore
