Hi all,
I am trying to start activity to a TabActivity intent and I keep
getting the same error. I have tried to make this as simplistic as
possible code wise...but no luck. My code is below the error message.
java.lang.RuntimeException: Unable to start activity ComponentInfo
{com.valpak.android/com.valpak.android.TabLayout}:
java.lang.RuntimeException: Unable to start activity ComponentInfo
{com.valpak.android/com.valpak.android.Categories}:
java.lang.RuntimeException: Your content must have a TabHost whose id
attribute is 'android.R.id.tabhost'

This is called in MyApp.java
startActivity(new Intent(getApplicationContext(),
TabLayout.class));
public class TabLayout extends TabActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost tabHost = getTabHost();
LayoutInflater.from(this).inflate(R.layout.tabs,
tabHost.getTabContentView(), true);
tabHost.addTab(tabHost.newTabSpec("tab1")
.setIndicator("Grid").setContent(new Intent(this,
Categories.class)));
}
}
Here is tabs.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+id/tabLayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
</LinearLayout>
Any help would be greatly appreciated.
