Question

I have two fragments inside my activity. That works fine. Now inside one of my fragment, I need two tabbed contents. And in each tab, I need to inflate a view. How can I do that inside the oncreateview method? is it possible?

Here is my XML layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="300dp"
android:layout_height="match_parent"
android:background="@drawable/texture_background"
android:baselineAligned="false"
android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="60dp"
    android:background="#000" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="60dp"
        android:layout_marginBottom="10dp"
        android:padding="10dp"
        android:text="header"
        android:textColor="#fff"
        android:textSize="25dp" >
    </TextView>
</LinearLayout>
<TabHost
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:visibility="gone" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </LinearLayout>
</TabHost>
</LinearLayout>

Here is my oncreateview method inside the fragment.

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
  View view = inflater.inflate(R.layout.saved_deals_fragment, container,false);
  TabHost tabs=(TabHost)view.findViewById(android.R.id.tabhost);
  tabs.setup();
  TabHost.TabSpec tab = tabs.newTabSpec("my tab content");
  tab.setIndicator("my tab content");
  tabs.addTab(tab);
  return view;
}

Here is my error:

do I need to provide any other details?

Answer 1

You don’t provide the content for your tabs. You could use a TabContentFactory to build a content like this:

TabHost.TabSpec tab = tabs.newTabSpec("tab1");
tab.setIndicator("my tab content");
tab.setContent(new TabHost.TabContentFactory() {

            @Override
            public View createTabContent(String tag) {
                if (tag.equals("tab1")) {
                    // create/inflate the view for the tab 1
                    return view;
                } else {
                    // the same as tab 1 for the other tabs if you have any             
            }
        });
tabs.addTab(tab);
