How to include layout inside layout?

Question

How to include layout inside layout in Android?

I am creating common layout. I want to include that layout in another page.

Answer 1

Edit: As in a comment rightly requested here some more information. Use the include tag

<include
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   layout="@layout/yourlayout" />

to include the layout you want to reuse.

Note that if you include android:id... into the <include /> tag, it will override whatever id was defined inside the included layout. For example:

<include
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:id="@+id/some_id_if_needed"
   layout="@layout/yourlayout" />

yourlayout.xml:

<LinearLayout
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:id="@+id/some_other_id">
   <Button
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:id="@+id/button1" />
 </LinearLayout>

Then you would reference this included layout in code as follows:

View includedLayout = findViewById(R.id.some_id_if_needed);
Button insideTheIncludedLayout = (Button)includedLayout.findViewById(R.id.button1);

Try this

<include
            android:id="@+id/OnlineOffline"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            layout="@layout/YourLayoutName" />

Answer 4

Use <include /> tag.

          <include 
            android:id="@+id/some_id_if_needed"
            layout="@layout/some_layout"/>

• Above layout you can used in other activity using

   <?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

From Official documents about Re-using Layouts

Although Android offers a variety of widgets to provide small and re-usable interactive elements, you might also need to re-use larger components that require a special layout. To efficiently re-use complete layouts, you can use the tag to embed another layout inside the current layout.

Here is my header.xml file which i can reuse using include tag

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFFFFF"
    >


    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:gravity="center"
        android:text="@string/app_name"
        android:textColor="#000000" />

</RelativeLayout>

No I use the tag in XML to add another layout from another XML file.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#f0f0f0" >


    <include
        android:id="@+id/header_VIEW"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        layout="@layout/header" />

        <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:background="#ffffff"
        android:orientation="vertical"
        android:padding="5dp" >


    </LinearLayout>
