Include the same layout multiple times

Question

I have a generic layout (common.xml) that I want to include many times in another layout (layout_a.xml). But it only shows me only once. What for?

common.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="@android:drawable/alert_light_frame">

        <ImageView

            android:layout_width="match_parent"
            android:layout_height="150dp"
            android:id="@+id/imageView"

            android:src="@drawable/test"

            android:scaleType="centerCrop" />

        <TextView

            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:layout_below="@+id/imageView"
            android:id="@+id/textView"
            android:text="test"
            android:layout_marginTop="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginLeft="10dp" />
    </RelativeLayout>
</merge>

layout_a.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/common" />

    <include layout="@layout/common" />
</LinearLayout>

Answer 1

The IDs defined in XML must be unique. You include two layouts that have views containing the same identifier.

Here is how you could fix it.

ps If there is no code in your first layout file that you do not include, this merge tag is useless.

Answer 2

btse, XML . :

<include android:id="@+id/common1"
    layout="@layout/common" />

<include android:id="@+id/common2"
    layout="@layout/common" />

Answer 3

I fixed the layout_height setting of the RelativeLayout parameter to 250dp as they overlap.
