I have a AlertDialog box with approximately 10 controls (text and TextView) on it. These controls are in a ScrollView with Alert
maybe you don't need to resize Dialog
add android:imeOptions="actionNext" to EditText(all but last) (it will add "Next" button to the keyboard - go to next EditText)
and add android:imeOptions="actionDone" to last EditText ("Done" button - hide keyboard)
now user should be able to click buttons
if you're creating textboxes in code use EditText#setImeOptions function
