Question

This is my first tabbed application for Android. I walked through the “HelloTabWidget” app on androids website, but I can’t figure out how to add content to the tabs. The FrameLayout stacks stuff on top of each other to the top left (from what I’ve read). I added a couple of textviews and an imageView, but it only displays the last item added. Is there a way to use Linear Layout instead of Frame Layout? If not, how can you place multiple views in the tab? The only thing I have done different from the example is I added a 4th tab. In one of the tab Activities I inserted the following code to try to get multiple items to display:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    

        TextView textview = new TextView(this);
        textview.setText("This is the About tab");
        setContentView(textview);

        TextView textview2 = new TextView(this);
        textview2.setText("About Test");
        setContentView(textview2);

        ImageView imgView = new ImageView(this);
        imgView.setImageDrawable(getResources().getDrawable(R.drawable.header));
        setContentView(imgView);
    }

Here is the link to the example I followed:

What is your layout xml file? I use this and I can stack several textview in every tab. TabActivity:

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

Activity inside tab:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:orientation="vertical" >
    <TextView android:id="@+id/textOne" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <TextView android:id="@+id/textTwo" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
<LinearLayout>

I’m a newbie myself, so there might be a better way to do it. This works for me, though.
