I’ve created a TabHost example with 1 tab which is running fine. I’m adding views in tabs with TabContentFactory using TabSpec.setContent(TabHost.TabContentFactory contentFactory)
But as soon as I try to add tabs by views in tabs using View/Resource IDs using TabSpec.setContent(int viewId) my app crashes. The code is as follows:
public class MainAct extends TabActivity implements TabContentFactory{
protected Resources res;
protected ListView listView;
protected LayoutInflater inflater;
@Override
public void onCreate(Bundle savedInstanceState) {
/*init*/
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
res = getResources();
listView = new ListView(this);
/*prepare tabs*/
TabHost tabHost = getTabHost();
TabSpec spec;
spec = tabHost.newTabSpec(res.getString(R.string.label_project));
spec.setIndicator(res.getString(R.string.label_project));
spec.setContent(this); // << this works perfect
//spec.setContent(R.id.list_item); // << CRASHES
//spec.setContent(R.id.list_item2); // << CRASHES
tabHost.addTab(spec);
}
@Override
public View createTabContent(String tag) {
return listView;
}
}
My XML files are as follows
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="22sp"
android:id="@+id/list_item">
</TextView>
and
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_item2"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="list_item2">
</TextView>
</LinearLayout>
Both of them defines IDs properly, yet they crash. I’ve already gone through following online tutorials:
http://android-pro.blogspot.com/2010/08/tabbed-applications-in-android.html
http://www.codeproject.com/KB/android/AndroidTabs.aspx
http://www.androidpeople.com/android-custom-listview-tutorial-example/
All of them describes how to add views in tabs using IDs, but none works for me.
All I want to do is to define a view in a layout file and add it inside my tab using IDs. Please help.

If you look at your XML files in your question, you will notice that you have no
TabHost, no TabWidget, and noFrameLayout. I will assume that these are in some third XML file that you declined to include in your question.Adding by ID only works for existing children of the
FrameLayout, such as in this sample project.What you may want to do is use the
<include>element inside yourFrameLayoutto load these other files in, or simply copy their contents into theFrameLayoutand eliminate the separate files.
