Шаг 1: Марка include_error_list_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ebebeb"
android:gravity="center"
android:orientation="vertical">
<!--android:background="#ebebeb"-->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/labelError"
android:layout_centerHorizontal="true"
android:src="@drawable/img_icon_error_list" />
<TextView
android:id="@+id/labelError"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:padding="10dp"
android:text="@string/err_error_list"
android:textColor="@color/color_app_font_primary" />
<ProgressBar
android:id="@+id/errorProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/labelError"
android:layout_centerHorizontal="true"
android:layout_margin="20dp"
android:visibility="gone"/>
</RelativeLayout>
</LinearLayout>
Шаг 2: Создание макета фрагмента fragment_abc.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="@+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="@+id/errorView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<include layout="@layout/include_error_list_view" />
</RelativeLayout>
</RelativeLayout>
Шаг 3: Схема привязки с JAVA.
