I just need someone to tell me if I understood correctly when to use <include>
and when <merge>
.
So, I make a header layout which I want to include into some other XML layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Header text" />
</LinearLayout>
And I include it into some other XML this way (which is pretty basic):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<include
android:id="@+id/header"
layout="@layout/top"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
This will work well, no issue about it. But in order to optimize the code, I have to use <merge>
in the layout which gets included. So the top layout
should not have a tag <LinearLayout>
but it must look like this:
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Header text" />
</merge>
Have I understood this correctly?
