Combining two widgets with each other

First, Sorry my English not good enough. Iam new in Android development. I have many widgets. Can I make them in one widget and when I need to add them I just add. Because Iam creating a library and I need to publish it on github.

<com.example.custom.view>
... />

These are all the views(widgets) I need them in one widget and I can add it in a layout.

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <HorizontalScrollView
        android:id="@+id/hscroll1"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <ScrollView
            android:id="@+id/vscroll1"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <LinearLayout
                android:id="@+id/linear2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="horizontal">
                <LinearLayout
                    android:id="@+id/linear3"
                    android:layout_width="wrap_content"
                    android:layout_height="match_parent"
                    android:orientation="vertical">
                    <TextView
                        android:id="@+id/textview6"
                        android:layout_width="wrap_content"
                        android:layout_height="match_parent"
                        android:text="TextView"
                        android:textSize="12sp"
                        android:textColor="#000000" />
                </LinearLayout>
                <View
                    android:id="@+id/linear4"
                    android:layout_width="1dp"
                    android:layout_height="match_parent"
                    android:background="#000000"
                    android:orientation="vertical" />
                <LinearLayout
                    android:id="@+id/linear5"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:orientation="vertical">
                    <TextView
                        android:id="@+id/textview7"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:text="TextView"
                        android:textSize="12sp"
                        android:textColor="#000000" />
                </LinearLayout>
            </LinearLayout>
        </ScrollView>
    </HorizontalScrollView>
</LinearLayout>
