Empty space above ImageView

问题

I got a static ImageView above a listView. But the imageView is showing some empty space above it.

How can i remove this empty space?

-when i use the the image as background of a TextView its perfectly alligned at parent top

Here is my xml for the ImageView:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:background="@android:color/background_light"
>

 <ImageView
        android:id="@+id/titlebartear"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="-5dip"
        android:src="@drawable/titlebartear"
        />

 <ListView android:id="@android:id/list" 
    android:paddingTop="0px" 
    android:tag="fileslist"
    android:fastScrollEnabled="true"
    android:smoothScrollbar="true"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:divider="@color/pijndagboek_light_blue"
    android:dividerHeight="2px"
    android:cacheColorHint="#00000000"
    android:layout_below="@id/titlebartear"
    />

</RelativeLayout>

A bit late, but may help others that stubmle across this:

"Adjust ViewBounds" worked for me, when a drawable automatically scales the height of the View it's set to. (Resulting in empty space above and below the image itself)

回答2:

set your image as background to your Imageview.

 <ImageView
        android:id="@+id/titlebartear"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:background="@drawable/titlebartear"
        />

回答3:

android:layout_marginTop="-5dip"

worked :S
