How to disable keyboard popup?

The keyboard pops up wherever there's an EditText item. I wan't to disable this popup from occurring automatically and only want the keyboard to appear when the user manually sets focus on the EditText field. I have added the following in my Manifest file but it doesn't appear to work:

<activity android:name=".AccountActivity" android:label="yourtime" android:windowSoftInputMode="adjustResize|stateHidden"></activity>
