How can you dynamically create a CheckedTextView in android [without creating a new implementation]?
It seems CheckedTextView is abstract ... (which does not make any sense at all) because I keep getting the compile time error: "Cannot instantiate the type CheckedTextView"
Using Android 1.5

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.
I need to display contents of a list of objects. Capture the selected items and later process it. I have been trying to find a tutorial on net but in vain. Could some one please advise me when can I find a tutorial. I know how to display a list but I want the CheckedTextView option.

View 1 Replies View RelatedI'm creating a view where it will list about 30 items, each with its own checkbox. I'm using the android.R.layout.simple_list_item_multiple_choice layout for this.
I have it displaying on the screen with my items and the checkboxes and it looks great. But here's the problem. When I click on one, it checkmarks, but when I scroll to the next page of items it shows the item in the exact same position is also checked.
Example of what I mean:
The emulator shows me 7 results on the screen at a time. If I click the checkbox for the first item, it enables. Then I scroll the screen down past the 7th item I see that the 8th item is checked, even though it shouldn't be. If I scroll down again to I see another item checked. The only one that should be checked is the one I actually clicked on. I can repeat this same exact problem for for any position in the item list. I must be doing something wrong in the code.
Here's my code -- not much to it:

View 2 Replies View RelatedI am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidget Provider {RemoteViews remoteViews; AppWidgetManager appWidgetManager; Component Name thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidget Manager, int[] appWidgetIds) { timer timer = new Timer(); timer.schedule AtFixed Rate(new WlanTimer(context, appWidgetManager), 1, 10000); The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask?
View 12 Replies View RelatedI'm trying to learn how to build apps for Android. The first simple app, which will become a component of a bigger app I hope to build, is to have a button on the screen where, when tapped, it adds something new to the view. For instance: Imagine a layout that only has a button:
[Create!]
When that button is pressed, the view gets a new row added to it:

In my main.xml layout file, I define a FrameLayout. Then in another layout file (say overlay.xml), I define another layout.
At runtime (onCreate) I want to create a new View object, set it's layout with overlay.xml, and add it to the frame dynamically. I need access to the elements of the overlay, to change text etc.
I use a LinearLayout and first I have a MapView and below the map I have a TableLayout with informations fields.
Now I would like to add additional information fields (e.g. a new TableLayout) when the user select a specific menu item on the Options Menu. I would like to have these fields either between the MapView and the TableLayout, or on top of the bottom area of the MapView.
How can I add this TableLayout with additional information fields dynamically after the user has selected a menu item? How can I show it below the MapView or on top of the bottom area of the MapView?
Is it possible to find dynamically what are the languages supported by the application? For example, I have strings for the following languages: English, French, Dutch and German. They are defined in their corresponding res directories: values, values-fr, values-nl and values-de. I want to give the user the possibility to choose between them and for this I want to load them. But I don't want to hard-code the choices. I tried to use: getApplication().getResources().getAssets().getLocales() But this method returns all the locales the phone supports.

I have three tabs in my Application. On an event under one Tab, i want to change the title of an another existing Tab. This is the title that we provide while adding the tabs to the TabHost.
Eg: TabHost.addTab(tabHost.newTabSpec("Tab2")).setIndicator("I need to be Changed dynamically").setContent....
In the above example, the title of the tab2 that i provided under setIndicator(), should be changed dynamically.
Is there any way to accomplish this.
I have an Android application which has four tabs (I use a main TabActivity with TabHost and TabSpecs).
In one of my sub activity (activity opened in a tab), i need to open a tab not by clicking on the tab title and i don't know how to do this.
For example, i have a button in my activity and when i click on it, it opens a different tab.
For the moment, it is what i do:
Intent intent = new Intent(myActivity.this, myTabActivity.class);
intent.putExtra("ComeFrom", true);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
Then in the TabActivity, if i get true reading the "ComeFrom" extra i open the wished tab but the problem is that it kills all the other activity. So, if someone knows a better (cleaner) way to do that trick.
How can i add image to my listview dynamically.
Here is My Code...
