<RelativeLayout
    android:id="@+id/topeFixContent"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:background="#FC9"
    android:gravity="center" >

    <FrameLayout
        android:id="@+id/frameLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"

            android:src="@drawable/logo" />

        <Button
            android:id="@+id/menuButton"
            android:layout_width="46dp"
            android:layout_height="32dp"
            android:background="@drawable/menu" />
    </FrameLayout>
</RelativeLayout>

<!-- Header aligned to top -->

<RelativeLayout
    android:id="@+id/header"
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:layout_below="@id/topeFixContent"
    android:background="#FA9"
    android:gravity="top"
    android:paddingBottom="0dp"
    android:paddingLeft="0dp"
    android:paddingRight="0dp"
    android:paddingTop="0dp" >

    <TextView
        android:id="@+id/hedderText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="0dp"
        />

</RelativeLayout>

<!-- Content below header  -->

<RelativeLayout
    android:id="@+id/content"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:gravity="center" >

    <TextView
        android:id="@+id/bdNewsTex"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:text="XX" />
</RelativeLayout>

</RelativeLayout>

我的查看功能code：

My View Function Code:

        @Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(context.LAYOUT_INFLATER_SERVICE);
    //View rowView = inflater.inflate(R.id.content, parent, false); 
                View rowView = inflater.inflate(R.layout.activity_main_news, parent, false);    
    TextView tv = (TextView) rowView.findViewById(R.id.bdNewsTex);      
    tf = Typeface.createFromAsset(context.getAssets(), "solaimanlipinormal.ttf");

    tv.setTypeface(tf);
    tv.setText(Html.fromHtml(items.get(position).getTitle()));      
    return rowView;
}
