XML : Bug in app while rotating android phone

hello guys i started to learn to build android applications via udacy. After a long troubleshooting i didnt find something that can cause the bug that i have. the bug is that when i rotate the phone the view seems to clone it self and not deleting the previous one if someone can help me ill be very happy. 1) normal state of app:

2) after rotation:

3) and after another rotation the application crashing

it never happend until i added the code in the xml file of the view:

      <?xml version="1.0" encoding="utf-8"?>    <!-- Layout for weather forecast list item for future day (not today) -->  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:gravity="center_vertical"      android:minHeight="?android:attr/listPreferredItemHeight"      android:orientation="horizontal"      android:padding="16dp">        <ImageView          android:id="@+id/list_item_icon"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:src="@mipmap/ic_launcher"/>        <LinearLayout          android:layout_height="wrap_content"          android:layout_width="0dp"          android:layout_weight="1"          android:orientation="vertical"          android:paddingLeft="16dp">            <TextView              android:id="@+id/list_item_date_textview"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="Tomorrow"/>            <TextView              android:id="@+id/list_item_forecast_textview"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="Clear"/>        </LinearLayout>        <LinearLayout          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:orientation="vertical"          android:layout_weight="1"          android:gravity="right">            <TextView              android:id="@+id/list_item_high_textview"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="81"              android:paddingLeft="10dp"/>            <TextView              android:id="@+id/list_item_low_textview"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="68"              android:paddingLeft="10dp"/>      </LinearLayout>    </LinearLayout>
