Hi all,
same problem here..
I've been trying to debug this problem all day long and can't seem to
find the breakthrough. I'm using tabhosts to create tabs on the main
screen, then I try to put list inside the other tab.To achieve that,
I'm using setContent(Intent e ) methods.. hoping that the list will be
contained on the tab.
Here's my errorr I'm getting: Did you forget to call 'public void setup
(LocalActivityManager activityGroup)'?
But as you see on the codes below, I already call tabs.setup();
So here's the structure of my program:
public class myHome extends TabActivity {
@Override
public void onCreate(Bundle home) {
super.onCreate(home);
// call the home screen
try {
setContentView(R.layout.home);
} catch (Exception e) {
Log.e("ERROR0001", e.getMessage());
// TODO: handle exception
}
// do the actual work here...
// manage tab
try {
final TabHost tabs = (TabHost)
findViewById(R.id.tabhost);
tabs.setup();
TabSpec tab = tabs.newTabSpec("TabOne");
tab.setContent(R.id.home_scroll);
tab.setIndicator("TabOne");
tabs.addTab(tab);
// tabs.setup();
tab = tabs.newTabSpec("TabTwo");
// tab.setContent(R.id.home_scroll_events);
tab.setContent(new Intent(this, myList.class));
tab.setIndicator("TabTwo");
tabs.addTab(tab);
tabs.setCurrentTab(1);
} catch (Exception e) {
// TODO: handle exception
Log.e("ERROR0002", e.getMessage());
}
}
It triggers the second exception (ERROR0002) when it reach
tabs.setCurrentTab(1)
Commenting out the setContent(Intent) method and use R.id, everything
works fine... minus the list I wanted...
Here is the error:
java.lang.IllegalStateException: Did you forget to call 'public void
setup(LocalActivityManager activityGroup)'?
I already add
<activity android:name=".myList"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar">
</activity>
on the android manifest file
Here's the content of myList.java
public class myList extends ListActivity {
@Override
public void onCreate(Bundle home_list) {
super.onCreate(home_list);
setContentView(R.layout.two);
String[] items={"lorem", "ipsum", "dolor", "sit", "amet",
"consectetuer", "adipiscing", "elit", "morbi",
"vel",
"ligula", "vitae", "arcu", "aliquet", "mollis",
"etiam", "vel", "erat", "placerat", "ante",
"porttitor", "sodales", "pellentesque",
"augue"};
this.setListAdapter(new ArrayAdapter<String>(this,
R.layout.row, R.id.label,
items));
}
}
where two.xml is simply like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Second tab"
/>
</LinearLayout>
and here is row.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="44sp"
/>
<TextView
android:id="@+id/information"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:text="life.."
/>
</LinearLayout>
I must have missing something here...can anyone please help?
Thanks.
