How to remove white space showing on top of scroll

问题:

I have the following scrollView. Everything works exactly as I want, except: there is a white space between the top of the scrollView and the top of the ImageView. What I want is for the image to be flushed at the top. It would be great too if the scrollView does not scroll past the bottom edge of the image as well. Thanks for all suggestions.

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scrollbars="none" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top"
        android:orientation="vertical" >

        <ImageView
            android:id="@+id/welcome"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            android:scaleType="fitCenter"
            android:src="@drawable/welcome_page" />
    </LinearLayout>
</ScrollView>

回答1:

To remove the top space, try using

android:scaleType="fitStart"

in the ImageView. As for the bottom space removal, maybe someone else can help you with that.

回答2:

Try adding android:layout_marginTop="-2sp" to your LinearLayout. This will move LinearLayout a bit higher, hiding the space.
