如何使用自定义形状创建对话框片段？

我有一个图标需要放在对话框窗口的顶部(透明).

对话框本身应该是:

对话框布局:

<FrameLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="80dp">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="40dp"
            android:layout_gravity="bottom|center">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/server_error_title"
                android:layout_marginTop="80dp"
                android:layout_centerHorizontal="true"
                android:textSize="20sp"
                android:textAllCaps="true"
                android:text="@string/server_error_title"
                android:textColor="@color/soft_blue"
                android:fontFamily="sans-serif-medium"/>
            <View
                android:layout_width="60dp"
                android:layout_height="2dp"
                android:id="@+id/server_error_divider"
                android:layout_marginTop="21dp"
                android:layout_centerHorizontal="true"
                android:layout_below="@id/server_error_title"
                android:background="@color/soft_blue" />
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/server_error_message"
                android:layout_marginTop="19dp"
                android:layout_centerHorizontal="true"
                android:layout_below="@id/server_error_divider"
                style="@style/TextDialog"
                android:text="@string/server_error_message"/>
            <View
                android:layout_width="match_parent"
                android:layout_height="1dp"
                android:id="@+id/server_error_large_divider"
                android:layout_marginTop="51dp"
                android:layout_below="@id/server_error_message"
                android:background="@color/greyish"/>
           <LinearLayout
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:gravity="center_horizontal"
               android:background="@color/white_grey"
               android:layout_below="@id/server_error_large_divider">
               <Button
                   android:layout_width="320dp"
                   android:layout_height="46dp"
                   android:id="@+id/server_error_close_btn"
                   android:layout_marginTop="30dp"
                   android:layout_marginBottom="30dp"
                   style="@style/TextButton2"
                   android:text="@string/server_error_close_btn"
                   android:background="@drawable/big_button_shape" />
           </LinearLayout>
        </RelativeLayout>
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/error_dialog_icon"
            android:src="@drawable/ic_error_circle"
            android:layout_gravity="center|top"/>
    </FrameLayout>

但我得到的是这个:

我是否需要自定义ViewGroup,或者可以更简单地完成它？

我正在尝试使用本手册在片段中实现选项卡:http://bit.ly/1yW6GUr

这是我的片段片段:

public class InputWaterLevelFragment extends Fragment {

private ViewPager pager;
private ViewPagerAdapter adapter;
private SlidingTabLayout tabs;
private CharSequence Titles[]={"Tab1", "Tab2"};
private int Numboftabs = 2;
public InputWaterLevelFragment() {
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_input_water_level, container, false);

    // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
    adapter =  new ViewPagerAdapter(getActivity().getSupportFragmentManager(), Titles, Numboftabs);

    // …
