<LinearLayout android:layout_width="700dp"
        android:layout_height="310dp" android:orientation="vertical">
        <TextView android:id="@+id/widget37" android:layout_width="fill_parent"

            android:textSize="10dp" android:textColor="#02284D" android:gravity="left">
        </TextView>
        <RelativeLayout android:layout_width="fill_parent"
            android:layout_height="150dp" android:layout_x="10dp">
            <ImageView android:id="@+id/bannert30"
                android:layout_width="fill_parent" android:layout_height="fill_parent"
                android:src="@drawable/front_screen" android:scaleType="fitEnd"
                android:layout_alignParentLeft="true">
            </ImageView>
        </RelativeLayout>

This is my code please help ?

You can use android:scaleType="fitXY" for the ImageView and another alternative is to set the image as the background of the layout.
