The problem is that I am using a TabHost and I need to be able to do this from one of the "child" activities. Is there any way I can go about doing this?

I have a tabhost that contains three tabs showing three separate activities. One of those activities needs to show the indeterminate progress bar on the title bar. If I set that activity as the MAIN, everything works fine. As soon as I use a tabhost to show the activity, I cannot show an indeterminate progress on the title bar for the tabhost activity. One way could be to have methods on the tabhost class that show the progress on it's title bar, but I do not know how to access those methods from outside the tabhost (for example, from another activity).

I want to be able to start and stop the progress bar when things changes inside each tab ativity.
View 1 Replies View RelatedI've searched and I know it seems some people frown upon using activities within tabs, but moving past that...how would I restart a tabbed activity while still keeping the tabs visible? I have an activity in a tab, I use the menu to create a new activity to update the tab's activity displayed info, when I return from the menu activity I want the new information to be displayed in the tab's activity. I am using startActivityForResult() from the menu choice, but when I return and try to restart the activity...it wipes out the tabs above(I guess as expected, but I want to re-launch the refreshed activity within the tab).
Creating the tabs:
TabHost host = getTabHost();
Intent home_intent = new Intent(constants.HOME_ACTION,
null, this, homeTab.class);
Intent inbox_intent = new Intent(constants.INBOX_ACTION,
null, this, inboxTab.class);
Intent stats_intent = new Intent(constants.STATS_ACTION, null,
this, infoTab.class);
host.addTab(host.newTabSpec(constants.HOME_TAG)
.setIndicator(getText(R.string.home_label),
getResources().getDrawable(R.drawable.icon))
.setContent(home_intent));
host.addTab(host.newTabSpec(constants.INBOX_TAG)
.setIndicator(getText(R.string.inbox_label),
getResources().getDrawable(R.drawable.icon))
.setContent(inbox_intent));
host.addTab(host.newTabSpec(constants.STATS_TAG)
.setIndicator(getText(R.string.stats_label),
getResources().getDrawable(R.drawable.icon)).setContent(
stats_intent));
Return from the menu activity in the tab's activity(updating database info): code...
I must be overlooking something because I am unable to get my TabHost to display in my Activity class.I am getting the dreaded force close when I try to run the app.It will work if I extend TabActivity, but I can't do that [details at the bottom] because once I move the code from my prototype project its going to be in a custom class that inherits from Activity.
View 2 Replies View RelatedI have created a TabHost and in 1 of the tab, I have added the content using
mTabHost.addTab(mTabHost.newTabSpec("tab1")
.setIndicator(getString(R.string.dialerIconLabel),
getResources().getDrawable(R.drawable.ic_tab_dialer))
.setContent(intent));
Is it possible for me to switch the content's activity programatically after I called 'addTab of TabHost'?
I have 3 classes in my example:
Class A, the main activity. Class A calls a startActivityForResult:
Intent intent = new Intent(this, ClassB.class);
startActivityForResult(intent, "STRING");
Class B, this class is a TabActivity:
Intent intent = new Intent(this, ClassC.class);
tabHost.addTab...
Class C, this class is a regular Activity:
Intent intent = this.getIntent();
intent.putExtra("SOMETHING", "EXTRAS");
this.setResult(RESULT_OK, intent);
finish();
onActivityResult is called in Class A, but the resultCode is RESULT_CANCELED instead of RESULT_OK and the returned intent is null. How do I return something from the Activity inside a TabHost?
I realize that the problem is that my Class C is actually running inside of Class B, and Class B is what is returning the RESULT_CANCELED back to Class A. I just don't know a work around yet.
I am developing one application for facebook. In this application when user click on login button i start WebView acitvity there user can login. On success of login i start activity from where user pressed that login button.
Now My problem is On main activity I get all friends list from facebook. That takes some time. So i want to show ProgressDialog, however that progress dialog is not showing up in main activity.
Here is my code.
On Login success i am using this method:

I have looked at the Android API and other posts here on stackoverflow, but have not been able to figure this out.
My app downloads files to the sd card. I would like to pop a "loading..." dialog while the file is downloading and then have it disappear when the download is finished. This is what i came up with using the android API:
CODE:.............
However the dialog doesn't actually show. when i debug it, it claims that it is showing, but it is obviously not on the screen.
I've implemented an onSaveInstanceState function in the main activity of my TabHost-based application. I need to save the state of various objects I am keeping in memory that I have all marked as serializable, as well as some basic int and string values. I have stepped through my application and watched it call the onSaveInstanceState function and presumably save everything without any manner of exception or problem. The issue is that my onCreate function is being called with a null Bundle value every time after I start the application again. I'm really at a loss and unsure why it would call the save but not pass anything into the create.
View 1 Replies View RelatedI've got a tab host activity started from a home screen shortcut. When my application starts it downloads information from a server using an AsyncTask. In the onPostExecute method of the AsyncTask I call setContentView to display the TabHost.When I start the homescreen shortcut by tapping on the shortcut using my finger everything works as expected, I download the information from the server and display the TabHost with the information in the tabs. However starting the application by navigating to the shortcut with the mouse wheel and then clicking on the shortcut with the mouse wheel leads to a trap in the framework code as soon as my application starts. This looks like a simple fix since mCurrentView is null at the time that this method is called - can this issue be addressed? Does anyone know of any workarounds?
View 5 Replies View RelatedI've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?
View 3 Replies View RelatedMy application involves doing some calculation on the first activity and sending the information to the second activity. So while the calculation is being done , I want to show a activity / progress / busy indicator on the first activity , before going to the second one. Is there any way of doing so, or an sample code that does the same. I was also looking out for the same by calling the calculation method after a delay so that the progress bar is shown first before the calculation is done , but this has also failed.

View 2 Replies View RelatedI have a service that downloads something from the Internet, it shows progress in notifications and in MyActivity (only when MyActivity is on foreground of course). How should the service post the progress to MyActivity? I know this could be done somehow with IBind but can I just simply do this in MyActivity:
MySevice.myActivity = this; startService(new Intent(....));
From MyService I can now call MyActivity's methods because I have a static reference to it in MySevice.myActivity, so I can call e.g. myActivity.sendProgress(63).
this button is shown on my start activity. After pressing it a new activity will be launched but this takes some time cause on initialization of that new activity some data is gathered from the Internet. This works half. The progress dialoge is shown but the progress wheel is not spinning.
Can somebody tell me why this happens?
Button b4 = (Button) findViewById(R.id.Button01);
b4.setOnClickListener(new View.OnClickListener() {
public void onClick (View view) {
final ProgressDialog pd = ProgressDialog.show(pak.this,
"", "Working..", true);......................
this is the current state/situation: I have an Activity which binds a Service which creates AsyncTasks which downloads various web resources. That works well, but of course the ProgressBar shows nothing. Previously i had an Activity which created an AsyncTask which downloaded some stuff. The AsyncTask got the View which holds the ProgressBar. So i could update the progress using onProgressUpdate and publishProgress. Obviously this doesn't work any longer because I have no reference to the ProgressBar.
