I’ve followed the Android tutorial for TabLayout, and I’m now trying to modify it by using a layout as well as an activity per tab. Unfortunately, when adding a TabSpec to my TabHost, my app is crashing with a “Resource ID Not valid” error.
I believe the error here is related to Dalvik not understanding my reference to my tab layout XML file, but don’t understand why this is the case. I have tried using additional <include> statements in my main.xml file, to no avail. Any help would be very welcome!
The crashing Java code:
public class TabLayoutActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources();
//mTabHost = getTabHost();
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
TabHost.TabSpec spec;
Intent intent;
//Search tab
intent = new Intent(this, SearchActivity.class);
spec = mTabHost.newTabSpec("search_tab");
spec.setIndicator("Search", res.getDrawable(R.drawable.magnifyingglass));
spec.setContent(intent);
mTabHost.addTab(spec); //this line crashes
//Allergies tab - when the above tab is commented out, this tab adds successfully
intent = new Intent(this, AllergiesActivity.class);
spec = mTabHost.newTabSpec("allergies_tab")
.setIndicator("Allergies", res.getDrawable(R.drawable.man))
.setContent(intent);
mTabHost.addTab(spec);
mTabHost.setCurrentTab(0);
}
}
The offending tab’s Activity:
public class SearchActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.id.search_tab_layout);
}
}
The other (working) tab’s activity (notice a layout is not specified):
public class AllergiesActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
textView.setText("Allergies");
setContentView(textView);
}
}
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TabWidget>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</FrameLayout>
</LinearLayout>
</TabHost>
search_tab.xml – is this not being included somehow?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/search_tab_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" xmlns:android1="http://schemas.android.com/apk/res/android">
</LinearLayout>

In your SearchActivity you have to set the layout. You try to set a view( from your layout) as your layout of the activity. Instead of
