[android-beginners] Re: ListView refresh in ListActivity
Thank you Mark!
In my deleteBeeyard() method, the finally {dbCon.close();} was the
problem.
I thought the SQLiteDatabase I get from getWritableDatabase() is
unrelated to the previously created Cursor (with
getReadableDatabase().rawQuery(...) ) for the CursorAdapter.
Obviously I didn't (and still don't) understand some basics. :-(

Re: [android-beginners] Re: ListView Selection Help
Can you give a little more detail about how the workflow of your application is supposed to work? We might be able to give some better suggestions on how best implement it. Seems to me like you have two different options, but they are drastically different and the one you would want to choose would depend on how your app works: 1. Switch to a new Activity. You do this by creating a new intent and passing in the class of the new Activity in the constructor. You then call startActivity from the current context (most likely an Activity) and that will launch the new Activity. However, you have to set up your activities with the correct behavior when you do this... e.g. when you go to the new activity should it replace the current one on the Activity stack or should the user go back to it if they hit the back button? See http://developer.android.com/guide/topics/intents/intents-filters.htmlfor more info on Intents... 2. Use some mechanism to store a setting (most likely using SharedPreferences but there are other methods available as well) and read that setting in the onCreate method of your activity to determine which layout to load. This would require the user to exit out of the application and restart it to see the new layout though... (but I have seen this mechanism used in quite a few apps, just put a note or something saying that changing the setting requires a restart). See http://developer.android.com/guide/topics/data/data-storage.html for more info on storing data... I'm sure there are many other ways to go about this but these seem like the most intuitive to me off the top of my head. Again, if you were to walk us through the entire user experience we might be able to give some more precise advice/feedback...

Well first of all there are 2 possible ways by which u might be
getting each row item... 1 is by defining them in an xml and inflating
them at runtime and the other is by directly initiating it through
code...
supposing that u have used the xml inflation method all u have to
do is define the list's width = fill_parent... and similarly in the
properties of the xml u have created for items u must have used Linear/
Relative layout in which all items reside... just change its width
parameter from wrap_content to fill_parent...
this will do the trick...
if it doesnt then we'll have to look at the xml of your row which u
inflate or incase of making it dynamically through code, we'll have to
have a look at the code...

[android-beginners] Re: ListView with multiple TextView
Thanks Jbrohan for the reply. I saw this Notepad example. In my case, I'm parsing an XML (RSS) and needs to show this in ListView. My actual requirement is to show the title in bold. So, I was planning to insert two TextView, 1st for Title and 2nd for Description, and set the property of the first one to bold. In the Notepad example, I saw that it uses DB to get the values (cursor) and to bind it in each row. So, do I need to insert the values to DB before accessing and displaying the values? thanks ash.

[android-beginners] Re: listview height
Yes I tried that thanks. I ended up just setting a static height. Everything I read says not to embed a listview in a scrollview (from the experts). Seems kind of short sighted to me. A listview offers a lot more than just the fact that it can scroll.

[android-beginners] Re: listview
Hi, You can try getIdentifier: http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier(java.lang.String, java.lang.String, java.lang.String) However, note this note: Note: use of this function is discouraged. It is much more efficient to retrieve resources by identifier than by name. If you still think this will be the best way to go about it, you should probably cache the resources ints after they've been determined Cheers, James On Wed, Oct 14, 2009 at 9:11 AM, frederic glouzon frederic.glou...@gmail.com wrote: hello, I am looking for a way to display the 200+ images of the countries of my listview.

The problem is that if i change some attribute ( for example v.setBackgroundColor(Color.BLACK) ) the selected view no longer stays selected. That is because selected is one of the background colors. A widget background is usually some form of ColorStateList. You can supply a simple color to setBackgroundColor(), but that only works if you do not intend to allow the item to be selected, for example. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html -- When I raise my flashing sword, and my hand takes hold on judgment, I will take vengeance upon mine enemies, and I will repay those who haze me.

Thanks, It Helps me a lotI tried to populate a listView by
extending Activity, not ListActivity..The list also contains two

tough to implement this application, but finally I overcome it, and
then the task was to detect which item or row is selected or clicked

[android-beginners] Re: ListView with addHeaderView Example?
Just in case anyone wants this in future, here is the solution to
having a ListView with an addHeaderView enabled with a permanent
TextView item at the top of list that doesn't move, even after you
scroll through the list. If anyone has a better implementation please
let me know as this doesn't extend ListActivity but just Activity.
Cheers!

Dynamically create your TextView in Java, or inflate it from a separate
layout XML file via getLayoutInflater().inflate(). You cannot move a
widget that is outside the list into the list in the fashion you are
trying to.

[android-beginners] Re: listview activity not stopping
From the log, you appear to have a null pointer exception, although
that could be a red herring. What happens when you step through it? Do
you get the same problem for all list items?
Looking at your code, you might want to consider simplifying it with a
switch statement, like:
switch (position) {
case SHOULDER:
startActivityForClass
(GymExercise.this,ShoulderViewController.class);
break;
case BICEPS:
startActivityForClass
(GymExercise.this,BicepsViewController.class);
etc.
Why do you call lv.bringToFront() for position 0?

Or, check out the samples with the SDK: http://developer.android.com/guide/tutorials/views/hello-listview.html http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/view/index.html (for the latter, scroll down to the eight samples under the Lists heading) If I have completely misunderstood your question, write back! -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?

[android-beginners] Re: Listview again
I am at a loss. I have tried multiple ways to get this done. I have tried setListAdapter also with the same results. The ListView is always blank. What am I doing wrong? When you are stuck, grab the code from an example bit of code (e.g., the SDK samples), get it working, then slowly manipulate it to get it to look like you want. ListView lvDrinks = (ListView)this.findViewById(android.R.id.list); //View lvDrinks = this.findViewById(android.R.id.list); String sType = extras.getString(drinktype); // lvDrinks.setAdapter(new ArrayAdapterString(this, android.R.layout.simple_list_item_1, R.array.beers)); beerscreen XML ?xml version=1.0 encoding=utf-8?

I would have your Buttons appear in the layout second and third, anchored to the bottom, then have the ListView appear below the TextView and above the upper Button. If you use hierarchyviewer (in your SDK tools/ directory), I suspect you will find that your ListView has zero height. Fixing it to take up the space between the TextView at the top and a Button at the bottom should help. If you are not comfortable with RelativeLayout, switch to LinearLayout for now and follow this layout example: http://developer.android.com/guide/samples/ApiDemos/res/layout/list_12.html Also, dump the background and textColor for now -- you don't need them right away, and all that will do is make it more difficult to diagnose your problem. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.
