Question

I’m trying to create an App that has a 2-tabbed activity, where tab1 has a picture and some text on top of it, and tab2 has two buttons users could click on (that should lead to further activities)

For some reason, I couldn’t get the buttons on tab2 to show; all I can see is the same picture from tab1. On closer inspection, I noticed that the buttons are hidden under the picture from tab1. What am I doing wrong? How do I make that picture go away and not show up on tab2?

The following is my code:

IndexActivity

public class IndexActivity extends TabActivity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    TabHost.TabSpec spec = getTabHost().newTabSpec("tab1");
    spec.setContent(R.id.tab1content);
    spec.setIndicator("tab1");
    getTabHost().addTab(spec);

    spec = getTabHost().newTabSpec("tab2");
    spec.setContent(R.id.tab2content);
    spec.setIndicator("tab2");
    getTabHost().addTab(spec);

    getTabHost().setCurrentTab(0);    

    }
}

My main.xml file goes like this:

<?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">
    <LinearLayout 
       android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:padding="5dp">
           <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">       
                <include layout="@layout/tab1"/>
                <include layout="@layout/tab2"/>            
           </FrameLayout>           
 </LinearLayout>

tab1.xml is like this:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent">
       <ImageView android:layout_width="fill_parent"
                  android:layout_height="fill_parent"
                  android:scaleType="center"
                  android:src="@drawable/pic"/>
       <ScrollView android:id="@+id/scrolltab1"
                   android:layout_width="fill_parent"
                   android:layout_height="fill_parent">
       <TextView  android:id="@+id/tab1content"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
                  android:background="#65000000"
                  android:text="@string/text"
          android:textColor="#ffffffff"
          android:textSize="20sp"
              android:padding="15dp"  
        />
       </ScrollView>      
</merge>

tab2 is like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tab2content"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:orientation="vertical">

    <Button
        android:id="@+id/button2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1.10"
        android:text="Button" />

    <Button
        android:id="@+id/button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1.10"
        android:text="Button" />

</LinearLayout>

Please help! I must’ve overlooked something but I can’t figure out what:(

Remove the following two lines from the FrameLayout in your main.xml and see what happens.

<include layout="@layout/tab1"/>
<include layout="@layout/tab2"/>
