EditText doubling out on rotate

阅读更多关于 EditText doubling out on rotate

I'm having an issue with an EditText control. This issue is only happening on this particular Activity and no other Activities with EditTexts. I have removed all setText calls for this EditText and the problem still persists. I am running Android 2.3.4 on my mobile device. It is a Nexus S and running stock Android.
