I have a remove assistant app, which allows customers to perform a
subset of functions of a desktop application, untethered. Results are
communicated back & forth via messages left at a license server. In
order to have a single source for the logic of the assistant, yet run
on multiple platforms (Swing, MIDP, & Android), I write a driver
composed of Database, Network, & Display pieces.
The Android driver is nearly complete, but I run into a brick wall
when it comes to Tabs. All views are instanced calling code, not XML
defined. I already have the view before I try to add it. I tried sub-
classing TabHost:
==============================================================
class DynamicTabHost extends android.widget.TabHost{
public DynamicTabHost(android.content.Context context){
super(context);
super.setup(); // errors with: Your TabHost must have a
TabWidget whose id attribute is 'android.R.id.tabs'
}
public void addTab(View view, String tabTitle){
android.widget.TabHost.TabSpec tabSpec = super.newTabSpec
(tabTitle);
tabSpec.setContent(new PreExistingViewFactory(view));
tabSpec.setIndicator(tabTitle);
super.addTab(tabSpec);
}
}
class PreExistingViewFactory implements
android.widget.TabHost.TabContentFactory{
private final View preExisting;
public PreExistingViewFactory(View view){ preExisting =
view; }
public View createTabContent(String tag) { return
preExisting; }
}
============================================================
As is shown in the code, it errors in setup. Looking further down in
setup() I will also get this exception too:
Your TabHost must have a FrameLayout whose id attribute is
'android.R.id.tabcontent
Is there a way to trick setup() into instancing me mTabWidget &
mTabContent members?
