android - Text input wildly off center in emulator, is it normal? -

in android emulators running api 19, reason, input placed edittext controls strangely off-centered downwards , left, in cases point not visible. wondering if common bug ignored or if suggest cause and/or solution fix this, not have physical devices running version of android , cannot test myself outside of emulator.

in case relevant, here xml layout:

i'm trying started android development , unfamiliar of commonalities may exist in platform pertain issues these emulators. so, please accept apology if turns out silly question. thanks!

to position edittext input text, use attribute android:gravity="x" x keyword want positioned. in case, use start position @ beginning.
