[android-developers] Soft Keyboard appears when entering on an Activity

I'm able to replicate a unusual issue with EditText. But it doesn't
happen on all devices.

Let's say you have the following layout:


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- ScrollView, GridView, etc also causes this. -->
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"></ListView>
<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="EditText"></EditText>
</RelativeLayout>

When your activity is created and displayed the first time,
softKeyboard will be shown even if user doesn't select the EditText
field.

I haven't reported this issue on Android trouble ticket system, since
I think this is an issue on manufacturer implementation (may be)

Devices we have:
Sonyericsson Xperia x10 (with Cyanogen 6) - Issue doesn't appear.
Motorola Milestone - Issue doesn't appear.
HTC Desire - Issue happens on it.
LG GX2 (T-Mobile) - Issue happens on it.

The recipe to replicate this seems to be, having a "ViewGroup" above
any EditText, will cause in certain devices, soft keyboard to appear,
when entering on an Activity.

I just would like to know if other ppl is able to replicate it, on
which devices, and if possible, what's the workaround.
