Question

I got a xml layout file like this:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    android:id="@+id/tabBar"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#474747"
    android:orientation="horizontal" >

    <ImageButton
        android:id="@+id/BtnSlide"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:background="@null"
        android:src="@drawable/lin" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:text="SteriaFIT Mobile"
        android:gravity="center"
        android:paddingLeft="12dp"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>

<RelativeLayout
android:background="#41413F"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
    <LinearLayout
        android:id="@+id/some_layout_item"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

</LinearLayout>

<View
    android:layout_below="@id/some_layout_item"
    android:layout_width="fill_parent"
    android:layout_height="5dip"
    android:background="@drawable/drop_shadow">
</View>

<ListView android:id="@+id/list" android:layout_width="match_parent" android:layout_height="wrap_content"
    android:background="#FFFFFF" android:cacheColorHint="#FFFFFF">
</ListView>


<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="To Next Activity" />

I only want to get the tabBar layout from this file into another xml layout file, i do this by including after @+id this way:

<include android:id="@+id/tabBar" layout="@layout/horz_scroll_app" />

but it seems to me that this line of code will include the whole layout file?

EDIT

should mention that this method will also give me the Button with the id button1

EDIT 2

Ok, so after putting the tabBar inside a new layout file like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/tabBar"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:background="#474747"
  android:orientation="horizontal" >

    <ImageButton
        android:id="@+id/BtnSlide"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:background="@null"
        android:src="@drawable/lin" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:text="SteriaFIT Mobile"
        android:gravity="center"
        android:paddingLeft="12dp"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

and included this to my orginal xml layout like this:

 <include  layout="@layout/tab_bar" android:id="@+id/tabBar" />

it seems to me that I cant register any OnClickListener to my ImageButton inside my tabBar layout. What I tried to do:

 View app = inflater.inflate(R.layout.tab_bar, null);
 ViewGroup tabBar = (ViewGroup) app.findViewById(R.id.tabBar);

btnSlide = (ImageButton) tabBar.findViewById(R.id.BtnSlide);
btnSlide.setOnClickListener(new ClickListenerForScrolling(scrollView, menu));

Can anybody give me a hint=

Answer 1

Include is used to include the whole xml file into the current layout. If you only want tabBar path then put them into a separate layout file then include them into the original view as well.

You will access the view normally:

LinearLayout tabBar = (LinearLayout) findViewById(R.id.tabBar);
ImageButton btnSlide = (ImageButton) tabBar.findViewById(R.id.BtnSlide);

I believe, the whole putting views together part is done when compile. So you treat it as you normally would to a view in xml layout.
