As I say in the topic, I want my WebView to prevent from reloading the webpage when another activity comes to the foreground or just when the orientation is changed. The reason why is because the WebView content is generated by Javascript/AJAX almost completely. After searching on a couple of forums, I found out many people suggested to use "saveState" and "restoreState" methods, but when I look the documentation, it says:Please note that this method no longer restores the display data for this WebView. See savePicture(Bundle, File) and restorePicture(Bundle, File) for saving and restoring the display data.So, here I was using that savePicture and restorePicture as it follows:protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); some other lines
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
if (savedInstanceState == null){
loadInicialWebUi();
}else{ mWebView.restoreState(savedInstanceState);
boolean restoredPic = mWebView.restorePicture(savedInstanceState, new File("savedDisplayWebView.temp"));
Log.d(TAG, "restored Picture:" + restoredPic);
@Override protected void onSaveInstanceState(Bundle savedInstanceState) {
mWebView.saveState(savedInstanceState);
boolean savedPic = mWebView.savePicture(savedInstanceState, "savedDisplayWebView.temp");
Log.d(TAG, "saved Picture:" + savedPic);
super.onSaveInstanceState(savedInstanceState);
}And well, those logs were revealing that it saves the picture, but it couldn't restore it. I suspect there might be something about the File references, but I couldn't think of a better way of getting the reference of the File I created when saving the state.Anyone thrilled?
I have a ListView that could have 4 different views for a row depending on the data for the row. I have the ListView working correctly overriding getViewTypeCount and getItemViewTYpe. I originally was trying to dynamiclly update the view type count as new views were inflated by forcing calls to getViewTypeCount because it was possible that maybe one or two views may be all that would be needed. The app never functioned correctly crashing after there was more than one view added. The problem was fixed by setting getViewTypeCount to always return 4. I noticed getViewTypeCount is automatically called on app start-up and never called again unless a force call is made. So I'm just curious if this can be changed dynamically or do you need to know the number of max views you can possibly have and override getViewTypeCount to return that max value.

View 3 Replies View RelatedI am having a problem with ListViews. After adding a few items to the list and it becomes larger than the layout, my cancel button disappears. Scrolling and everything else on the ListView still work fine, but it replaces the views I have below it. Anyone else run into this issue? Am I missing something?
Here is an example layout:
CODE:...................
I'm trying to make a ListView when every item in that list can be a different type of View. for example the list could be: 1. TextView 2. ImageView 3. MyCustomView
I understands that in order to make a list I need to use an Adapter. the problem is that the Adapter uses a single layout for all of the list items, which will not support the different views.
my goal is to make an abstract View list when I can dynamically add and removes items in that list (each item is a View or subclass of it).

I have a listview that is populated by a couple threads that pull in data from the network. Before that data comes in, there are some default values displayed. When the screen loads, there are 6 items displayed, each with the default data. The 1st (index 0) loads and is updated on the screen, and then number 6 (index 5) is updated with that same info. Then, item 2 (index 1) loads, and then item 5 (index 4) mirrors that data. Then item 3 loads, then item 4 reloads with the correct data, then then item 5 with the correct data, then item 6. Why are items 5 and 6 briefly showing the data from other elements in the list? I can't figure out what in the world could be causing this.
View 7 Replies View RelatedI have the following code to intantiate a SimpleCursorAdapter to use with a ListView. As you can see I have passed the R.layout.log_item to display the list items, and one value/control to bind to (TripDate).
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.log_item,c,new String[] {DBAdapter.KEY_LOG_TRIPDATE},new int[]{R.id.txtTripDate});
This works. I currently only have one widget in the layout xml, a TextView to hold the TripDate.
How do I pass multiple binding parameters for the additional widgets in the layout? So I can also display other info.

View 9 Replies View RelatedIm using ListView to to show some custom data, once data is updated in the adapter i call notifyDatasetChanged(), so the view will get updated, all of this works well, my issue though is i would like to run an animation once only on items that got changed when the adapter was updated. currently i keep a copy of all the changed objects and i tried to animate the correct items through the getView() call.
However if i do it only once for every getView call then i see no animation most of the time on items that changed. if i continue to do so in successive getView calls i see animation on items that don not change as well and also the ones that changed get animated again and again.
Im guessing sometimes android calls the getView() for other reasons than showing the generated view immediately, and thats the reason it doesnt work if i do it once.
I have TabActivity that uses 2 other ListActivities for the tabs. Both underlying ListViews are set to CHOICE_MODE_MULTIPLE. When I run the following sequence of events, I get a strange result: 1) Setup one activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 2) Reorient the screen (open the keyboard) 3) Setup the second activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 4) Switch back to the first tab
At this point, I can see in Eclipse that although (of course) each ListView is a distinct object, the internal variable used to store the checked state of items, called mCheckStates, is the SAME OBJECT REFERENCE in each of the ListViews.
Clearly this is an issue, since the two views should not share the checked state of items between them.
If I skip step #2, this does not occur
Here is a bit more detail:
After Step 1: ListView1 is object reference @1, ListView1.mCheckStates is object reference @2
After Step 2: ListView1 is object reference @3, ListView1.mCheckStates is object reference @4 (the reorientation recreates the views)
After Step 3: ListView2 is object reference @5, ListView1.mCheckStates is object reference @2 <-- note the reuse of this reference from step #1, not sure how/why
After Step 4: ListView1 is object reference @3 (unchanged), ListView1.mCheckStates is object reference @2 (changed) <-- same as ListView2.mCheckStates
I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
I want to ask where does the defaults values of memory min-free values of a Rom reside? I mean what file I would have to edit to edit those values?
View 1 Replies View RelatedI am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.
View 2 Replies View RelatedIs there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

View 2 Replies View RelatedI have implemented a BroadcastReceiver which is triggered by the AlarmManager. The AlarmManager is initialized on BOOT_COMPLETED. So i have to declare the receiver in the manifest.
My problem is that i want the BroadcastReceiver only to do something when none of my own activities are in the foreground (aka the user is not interacting with my application). I pull information from a remote server and don't want to notify the user if he is currently in my application anyways.
So far i have not managed to find a way to determine if my application is in the foreground. Is there a way to do such thing? The ActivityManager tells me if my application is running but not whether it is in the foreground.
Is there a way to call startActivity(Intent) without the newly started activity displacing the current one as the active, foreground activity?
If not purely so, are there near approximation to this effect that can be done, such as mimicking a back keypress event right after calling startActivity()? If so, which means is preferred?
Anyone else had abny issues with the back up restore function? I tried to do a software update, to which something seems to have happened. All i can see for the time being is an update to the virtual keyboard. Anyway, lost apps, contacts etc, so went into the menu on the handset and selected back up, restore. Restored numbers etc to phone book and over 150 number details are missing. The back up utility doesn't seem to have backed up all my numbers. Also, any personal photo's of callers etc have either vanished or the photo's are now against the wrong people. So much for this back up service, it's going to take hours, if not days to try to get the phone back tot he way it was!
