Why the editText cannot input after I add password.setText("") in onResume function?

I made an Android application. One of the parts is login. In this activity, I have a EditText which name is password. After press the login button, it will open a new activity to prepare to do something else. If validate the password fail on the server, I will finish() the new activity and back to the old one. I want to clear the password which have been entered. so I use password.setText("") in the onResume() method.

But if I type wrong password for several times, as you see, the activity open and close several times, the EditText password cannot input anything until I close the activity and open it again.

here is the logcat info:

Anybody know why? BTW: If I remove the password.setText("") part. it will works fine.

This looks like it might be related to what you're seeing.
