Hint in Android

I tried to show a hint in the EditText of my form, but i can't see that hint that i have set in the XML Layout while my application gets deployed, but i can able see the hint in eclipse designer view, but while getting deployed the same hint suppose to appear is missing, i tried with all the possible ways still i could not get the hint in the EditText... This is one of the Edit Text layout that i have used..

<EditText android:id="@+id/SetTimerSec_EditText01"
    android:layout_width="60sp" 
    android:layout_height="40sp"
    android:singleLine="true" 
    andro开发者_运维问答id:layout_x="220sp"

It seems like a SDK bug, or at least related to one.

The hint shows up if you remove the following:
android:gravity="center"

add android:ellipsize="start" and your hint will show up and be centered!
