Android : How Can I Access Dynamic TextView?
Jun 9, 2010
I have created a table with 2 rows in it. Each row has 5 TextViews with a default text of 0. There is also a button outside of the table. I am trying to figure out how to update each of the TextViews in each row on each successive press of the button. So on the first press of the button the first TextView in the first row should update to 1. On the second press of the button the second TextView in the first row should update to 2...etc. I can't figure out how to do this programmatically without having to code it all - is it possible? Basically I guess I need to build up the ID of the TextView dynamically. So if the TextViews have ids as item1, item2, item3 etc. Then I need to build up the findViewById(R.id.item + i); Obviously this is not possible but is there a way to do this?

I want to create a TextView that will stretch the width of the screen and use a textsize that will keep the text on one line and fill the width. So bigger words would be smaller fontsize and smaller words would be bigger font size. I tried digging around in the docs under TextView but could not find what I needed.

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

I'm trying to create a textView in the parent activity onActivityResult but the textView does not appear. There is an ImageView that takes up the whole parent activity. I can create a textView and place it, and it should go on top of the imageView?
In the parent class:
[HIGH]private void addClothes(int menuId) {
Intent chooseClothesIntent = new Intent(this, ChooseClothesActivity.class);
chooseClothesIntent.putExtra("menuId", menuId);
startActivityForResult(chooseClothesIntent, 1);
}[/HIGH]
[Code]...
then in my new activity:
[HIGH]@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
try {
ClothingItem ci = mListContents.get(position);
String imagePath = ci.getImagePath();
[Code]...

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.

I have a problem with TextView in Android
I am making an application like Facebook. In m.facebook.com, when I open it I see they do one thing specailly.
(Alice) is writing on (BackStreetBoy1010938920) wall
Because the width of Mobile screen is small so the real message like tha
(Alice) is writing on (BackStreet
Boy10101009393) wall
I guess they use TextView for (BackStreetBoy1010938920) but I can't do like this.

I am new to this android stuff and SQLlite etc.I am going to log some numbers at a certain interval, and will put them into a dynamic histogram, by dynamic i mean that there will be a maximum number of samples in the histogram, the histogram and age stuff should be persisted either in db or plain file.For simplicity, I would like the samples to be stored in a blob type datafield, but i cannot se if this is possible. Alternative i could have another table with the samples Or I could simply have files with filename = name and content = samples.my concern might be unclear by now, but put simply, what is most effecient regarding power usage?

I define once in my /xml/widget.xml the minwidth. but what can i do when I need to inflate different sizes from my widget layouts for 1 one my 3 widgets thats fine, but the last 2 widgets would just need one icon size, so they always need the width of 2 icons. also when I make minwidth smaller.. it fits with the other 2 widgets but the large widget come cutted.How to solve that. I cant believe to create a total new receiver and a new /xml/widget2.xml just for another size?!

I need a gallery to be able to hold up to thirty custom views. These views need to added or removed whenever, they also need to be able to be display in a display bow beneath the gallery. How do I do this?I looked at the doc file for arrayadapter but it requires me to use a reference Id for each view I add, but each view is all java coded. Should I just use setId upon creation of the view and just throw that id into the array adapter, or is there a way to create one without using resource id's?

I'm trying make a View that divide the screen in three sections. The first section should be 200dip high, the third section should be 50 dip high and the middle section should take the remaining place in the middle. Is there any way to implement it? I tried some ways but either it doesn't work or the app crashed.

I've been reading the (shoddy) documentation for the Google Maps API (MapActivity et al), and I think I have roughly worked out how it works. It seems that if you want to add a marker overlay you can use ItemizedOverlay easily, but you have to add all your markers at once. There doesn't seem to be any way to remove them.
What I want to do is query markers from an online database as the user pans around (in the same way the actual map tiles are fetched). Is there a simple way to do this?
As far as I can tell I need to subclass Overlay and implement the draw method, but where is the best place to put the code that fetches new markers when the map is panned? There doesn't seem to be an onMapChanged() method anywhere. My best guess is MapController.onKey() but that seems wrong.

I'm trying to find a way to open resources which name is determined at runtime only. Let me explain in more details. I want to have a XML that references a bunch of other XML files in the application apk. for the purpose of explaining lets say the main XML is main.xml and the other XML are file1.xml file2.xml...fileX.xml...
what i want is to read main.xml, extract the name of the xml I want (fileX.xml) for example. and then read fileX.XML. the problem I face is that what I extract form main.xml is a string and I can't find a way to change that to R.raw.nameOfTheFile

I have a layout which might be a bit unusual.
The structure is the following:
CODE:..............
My customRelativeLayout at the bottom of the XML has a XML layout too:
CODE:.............
My CustomRelativeLayout:
CODE:.....................
What I want to do: I want to be able to change the position of my CustomRelativeLayout. It should be follow my touch. Its smaller than the SurfaceView and should "slide" above following my touch...
There are two problems:
The onTouchListener bind to mLinearLayout (in CustomRelativeLayout) is only triggered once and only for ACTION_DOWN. I see the log output only once The note never changes the position, it is never redrawn with the changed matrix... I see the output stated in onDraw never after the touch happened.
First might be because the SurfaceView also handles touch events. But I thought if the CustomRelativeLayout handles it first, it should work.
Thanks to Xil3 I was able to remove the wall I was run into...
Here is my solution:
My note xml:
CODE:.................
And here is my constructor:
CODE:..................
I also found a bug/feature/issue, which is absolutely new for me: When I remove the background in my note root element (which is currently transparent) the note is only visible within the 200dp width/height I have set in the inner LinearLayout. So its not fill_parent, its wrap_content even as I set it to fill_parent. So layout_width and layout_height only use the given fill_parent when a background is set...

Is it possible to dynamically load classes from a URL into your application in the same way as a desktop application can? For example, can you do a simple boot-strap application which you install onto the device, that boots up loads the main jars required for the applications from a server, or from a local jar on the SD for example?
