I have a listlayout with items in it that looks like this:
There is first an ImageView (the light) and then two textViews. All of this inside a TableLayout. (source here: http://code.google.com/p/switchctrl/source/browse/trunk/android/res/layout/device_switch.xml)
I want to have a rotating animation of a loading indicator Ontop of this light when this particular device (light) performs an action or an action is performed on it.
How do I put an animation ontop of this light imageview?
How can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

I am writing an Android app, part of which will be a survey involving multiple pages of checkbox question and answers. I have created an activity to display the question and options (from the DB) and what I want to do now is when i press the "Next" button it should just reload the current activity with the next question set from the database. (the activity starts with survey.getNextQuestion() - so its just a case of refreshing the activity so it updates)

I was getting this cheapo tablet ready to sell and wanted to reset it to factory settings but there was not an option to do that in its settings so I found "format internal" and without even thinking selected that. Well needles to say I can no longer start it up. This tablet has no model number on it, not even in the instructions.

I have a Tabview with 3 tabs (each having their own activity). I have a tab that parses a RSS feed. How can I refresh this feed via a menu button? I tried doing the following but I lose the tabs above of course.

I have one activity. OnCreate the activity gets the source (html) of a web page to a string and presents the result (after parsing it a bit) in a textview. I would like the activity to reload/refresh periodically to always present the latest information.

View 3 Replies View RelatedI have an application, where I need to change the language through a settings menu. Now this part works perfectly, but it doesn't change the language for activities that have gone through onCreate.
I got a TabHost, and 2 tabs in it, from the tabs you can get to settings.
Refreshing the TabHost isn't an issue, as it's fairly small, however both the 2 tabs are quite large views, and having a function to manually update all the strings seem unnecessarily difficult. Is there any way to force the activity to recreate itself and trigger a new onCreate?
I tried having a static function in the tabhost that clears all tabs and recreates them, this refreshes the tab titles, but not the content in the tabs.
When i load a url in a webview. it loads perfectly. but i touch anything in that webview its redirected to the browser by default.

I've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.

What Should i do to Avoid Reload ?

could some one please suggest me how do I perform the reloading part.

View 7 Replies View RelatedI have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.
Solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?

View 3 Replies View RelatedI tried to install the viper one rom. Everything installed fine, and I followed the instructions listed. Now my phone boots up to a black screen, has sound of turning on and that is it. The keys at the bottom light up sometimes, but nothing else happens. I can't get my computer to see it as a drive so I can't load any other roms up. And I cannot reload viper because it is no longer showing.
View 1 Replies View RelatedAs 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?
Today i noticed that when i leave an application either by backing out or pressing home, sense has to reload. It first flashes the HTC sign, then it takes about 10 seconds to load my home screen. Now this morning i installed an update for "spare parts". Im assuming this was the culprit so I un installed. Still having the problem though. Extremely annoying!
