Hello!
You can use few methods to change this behaviour of EditText.
First - you can define in xml layout this parameters:
<LinearLayout
android:focusable="true" android:focusableInTouchMode="true"
android:layout_width="0px" android:layout_height="0px"/>
<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/text"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:nextFocusUp="@+id/text" android:nextFocusLeft="@+id/text"/>
AutoCompleteTextView also as EditText can be set as an example.
Second - If it's the problem of the virtual keyboard, that popup by gain focus on element, see the AndroidManifest.xml element documentation.
android:windowSoftInputMode="stateHidden"
- always hide it when entering the activity
or android:windowSoftInputMode="stateUnchanged"
- don't change it (e.g., don't show it if it isn't already shown, but if it was open when entering the activity, leave it open).
