I have a code for populating content for tabs dynamically. First time it works ok, but when I want to replace tabs (and their content) with new content - tabs are changed but tabs' contents are not, how can I clear completely whole TabHost and replace with other content? code...

Since the TabHost API does not offer a way to change existing views or activities, what is the preferred means to replace an existing tab?
I only know of: clearing the tabs and adding them again. Is there an alternative? Or is this really not provided by design?
I have to create tab bar in my application in which i have to navigate between activities under single tag. So that i tried many ways one of which is to clear all tabs from tabhost and create new tabs and add on tabhost but it gives me unexpectedly close error.
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'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?

i want to clear the activity stack and replace it with a new activity as the root activity, even if that activity exists somewhere on the stack (or not). i see FLAG_ACTIVITY_CLEAR_TOP and FLAG_ACTIVITY_NEW_TASK, but it's not obvious to me how to use those in conjunction to achieve what I want. it's like i want to completely restart the task with some activity that i specify as the new root.
What exactly does HTC Sense Clear Data actually clear? That may be a solution to reverting back to 5 homescreen pages instead of 7 without having to do a factory reset. Just curious as to what I am going to mess up? Will i just have to personalize the homescreen again, put widgets up, reconnect to fb, twitter, myfaves, etc. It's not going remove any 3rd party apps, just make me create new widgets, etc..?
View 3 Replies View RelatedThis may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

I'm trying to create multiple tabs, each with a different Activity. The only downside is i'm using a custom layout file thus my class extends an Activity rather than a TabActivity. While trying to run, it fails and suggests calling TabHost.Setup(ActivityGroupManager agm)
View 3 Replies View RelatedIn a TabHost widget, I can create a new tab with its content (Intent) using TabHost.addTab(TabHost.TabSpec tabSpec).
We can remove all tabs we created by calling clearAllTabs(), but I can't figure out how to remove the tab or just replace the content (Intent) inside the tab with new Intent.
so what I need something like removeTab(int index)
I have a tabhost...

here's my source code...
I currently have a TabHost with 3 tabs.The content of each tab is an activity. The first and second tab make HTTP connections.The first tab still uses the UI thread (which i'm changing) so it would explain the slow orientation change since it's creating a fresh activity and making all those connections again. What I don't understand is why if I am on say Tab 3 which makes no connections at all does changing the orientation take such a long time (up to 5 seconds).In playing around with the TabWidget I noticed something that may be related.

Some times when I select the second tab it dissapears and a black background is shown. This issue does't happen when the first tab is shown You can find a picture of the issue here: http://1.bp.blogspot.com/_2UoVsSnv2Gk/Sl8u2o-tvzI/AAAAAAAAAJc/RMUMfKU...
This issue happens randomly and i can't reproduce it consistenly.
I have a TabActivity. Within this activity (in the onCreate method) I create a TabHost and a TabSpec and do a tabSpectSearch.setContent(intenSearch); The Indent is created using intentSearch = new Intent().setClass(this, MyActivity.class);
As far as I already found out the class MyActivity is instantiated when I select the tab, to which it is connected. Is there a way from my TabActivity to force the creation of all activities (all tabs) at once?
I want to get rid of horizontal scroll bar in TabHost. It's there even if TabWidget is on top.
View 1 Replies View RelatedI meet an issue: my activity cannot return result.
I created an activity which has one TabHost. I added three tabs using mTabHost.addTab. Every tab will launch an activity(activity A, activity B, activity C). In activity A, it will call startActivityForResult to start activity A1. The issue is activity A cannot get any result after A1 finish.
What is the reason? How should I do if I want to get return value?
I'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 am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.
I have a tabHost with tree tabs. How can I access a specific tab from the tabHost activity when this tab is not active at the moment.And a second question to this topic.How can I access the activity of a tab from another tab?I need this, because I have to update the second tab when something changes on the first tab.
