Updating Android Tab Icons
- by lnediger
I have an activity which has a TabHost containing a set of TabSpecs each with a listview containing the items to be displayed by the tab. When each TabSpec is created, I set an icon to be displayed in the tab header.
The TabSpecs are created in this way within a setupTabs() method which loops to create the appropriate number of tabs:
TabSpec ts = mTabs.newTabSpec("tab");
ts.setIndicator("TabTitle", iconResource);
ts.setContent(new TabHost.TabContentFactory(
{
public View createTabContent(String tag)
{
...
}
});
mTabs.addTab(ts);
There are a couple instances where I want to be able to change the icon which is displayed in each tab during the execution of my program. Currently I am deleting all the tabs, and calling the above code again to re-create them.
mTabs.getTabWidget().removeAllViews();
mTabs.clearAllTabs(true);
setupTabs();
Is there a way to replace the icon that is being displayed without deleting and re-creating all of the tabs?
