View 2 Replies View RelatedAndroid :: ListActivity And SQLiteDB - Can't Refresh List
Oct 29, 2009What is the best way to display a database queries results on the screen using ListActivity? I need the db queries to run in the background and I also need to be able to make different queries and refresh the screen according to the query result. I am using the ListActivity class with a SimpleCursorAdapter in order to display the db queries result on the screen. At the moment, I am doing the db queries at the background using AsyncTask, when getting the results I want the list to be updated immediately, but I can't find a good way to do it. It worked only when I used the changeCursor(cursor) function to set the adapter to a new cursor with the new results. But I don't think this is a good solution since it seems to stuck the UI for a while. I also found some posts about notifyDataSetChanged() but I am not sure if/how/when I should be using it with a SimpleCursorAdapter to make the view refresh.

Android :: ListActivity Design / Changing Content Of List Adapter
May 31, 2010I would like to write a rather simple content application which displays a list of textual items (along with a small pic).I have a standard menu in which each menu item represents a different category of textual items (news, sports, leisure etc.).Pressing a menu item will display a list of textual items of this category.Now, having a separate ListActivity for each category seems like an overkill (or does it?)
Naturally, it makes much more sense to use one ListActivity and replace the data of its adapter when each category is loaded.My concern is when "back" is pressed. The adapter is loaded with items of the current category and now I need to display list of the previous category (and enable clicking on list items too)
Since I have only one activity - I thought of backup and load mechanism in onPause() and onResume() functions as well as making some distinction whether these function are invoked as a result of a "new" event (menu item selected) or by a "back" press.This seems very cumbersome for such a trivial usage.Am I missing something here?
Android :: Integrate ImageButton With ListActivity Failed - List No Longer Selectable
Jan 30, 2010I have a working ListActivity class. Each of the list item consists of an ImageView and a TextView. However, when I try to replace the ImageView with ImageButton, The list becomes unselectable. The onListItemClick or any other function no longer get called when press a list item (Although the track ball can still focus a list item, but nothing more can be done). I have searched the forum and also the internet and failed to find any such working example, apart from one guy reporting a similar problem but with no answer.Code...

View 1 Replies View RelatedAndroid :: Use Built In Image Viewer To Display Image
May 13, 2010Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

Sep 23, 2010I have a String countries[].now when i click a button then on the onClick event this abc array is filled.suppose it is filled with the name of 10 countries.These 10 countries should be visible as a list so that i can choose any 1 country among the list. but i am not able to show them as a list.

Android :: Image Display From A URL
Jun 17, 2009I want to display an image from a url, for this I defined the ImageView first as,
<ImageView android:id="@+id/imagename" android:layout_width="wrap_content" android:layout_height="wrap_content" />

super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView imgV = (ImageView)findViewById(R.id.imagename);
Now how should I supply the url of the image from where it should fetch the image ever time. I have seen the function setImageURI but it is not clear how to give the url.Any clues?

View 1 Replies View RelatedAndroid :: How To Display An Image From SD Card In WebView
Jul 13, 2010When I started to display an image from the SDCARD in WebView, I got errors like:
" Not allowed to load local resource: file://".
I�ve found a solution for this, and you don�t even have to care about ContentProviders�
Here�s an example:
/* Using WebView to display the full-screen image */
WebView full = (WebView)findViewById(R.id.webview);
/* Set up the Zoom controls */
FrameLayout mContentView = (FrameLayout) get Window().
getDecorView().findViewById(android.R.id.content);
final View zoom = this.full.getZoomControls();
mContentView.addView(zoom, ZOOM_PARAMS);
zoom.setVisibility(View.VISIBLE);
/* Create a new Html that contains the full-screen image */
String html = new String();
html = ("<html><center><img src=""+fileName+""></html>" );
/* Finally, display the content using WebView */
full.loadDataWithBaseURL("file:///sdcard/data/data/com.youproject.example "utf-8",
""); Hope you found it useful, let me know how it works for you!
