I'm fairly new to Android and Java for that matter, and am having a
context issue - I have a Spinner within a TabWidget within another
TabWidget, and on the code side I have my main class which is a
TabActivity, in which I set the intent of a particular tab to another
TabActivity, in which I set the intent of a tab to an Activity which I
set the content view to a layout where I have my Spinner (hopefully
that made sense). Anytime I click on the spinner and it attempts to
launch the dialog for the spinner it gives me a bad token error. From
what I've read, it's because my spinner has the wrong context, but
since I'm not actively setting my context (I created the spinner in
XML), and I can't seem to find a method or exposed property to set the
context of the spinner...well you get the point, I'm lost on this one
despite reading other people's similar issues. Here's my code:
Main:
public class Star_Android_Activity extends TabActivity
{
public static void main(String[] args) {
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be
reused)
intent = new Intent().setClass(this, Pick_Activity.class);
// Initialize a TabSpec for each tab and add it to the
TabHost
spec =
tabHost.newTabSpec("pick").setIndicator(LinearLayout.inflate(this,R.layout.tab_header_pick,
null))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
Sub-Tabs:
public class Pick_Activity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pick);
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Reusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
intent = new Intent().setClass(this,
Pending_Activity.class);
spec =
tabHost.newTabSpec("pending").setIndicator(LinearLayout.inflate(this,R.layout.tab_header_pending,
null))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
}
Child Activity:
public class Pending_Activity extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.pending);
addSpinnerValues();
}
public void addSpinnerValues()
{
Spinner spn = (Spinner)findViewById(R.id.spnPick);
List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
ArrayAdapter<String> dataAdapter = new
ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,
list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spn.setAdapter(dataAdapter);
}
}
The xml files for Main and and Pick are basically copies of the hello
tabwidget tutorial, and my pending.xml is just a FrameLayout
containing a few buttons and my spinner. I can post the code if it
helps, but I was having issues posting anymore code (character limit
perhaps).
Any help on how to properly set my contexts (and a small explanation
if it's not a hassle) would be greatly appreciated!
