Android adjustpan not working after the first time

My problem: starting from the second time the software keyboard is shown on the screen, it entirely hides my EditText.

Attribute android:windowSoftInputMode="adjustPan" has been specified in the AndroidManifest.xml, but it works only the first time.

I have the following layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<LinearLayout
android:layout_width="match_parent"
android:layout_height="464dp"
android:gravity="top"
android:orientation="vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp" >

<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="10"
android:background="#E3E3E2"
android:gravity="top" />

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >

<EditText
android:id="@+id/addListText"
android:layout_width="0dp"
android:layout_height="48dp"
android:layout_weight="10"
android:contentDescription="@string/addItemContentDescription"
android:gravity="bottom|center_horizontal"
android:inputType="textLongMessage"
android:textColor="#E3E3E2"
android:visibility="gone" />

<ImageButton
android:id="@+id/addTextListButton"
android:layout_width="0dp"
android:layout_height="48dp"
android:layout_weight="1"
android:layout_gravity="right"
android:background="@android:color/transparent"
android:contentDescription="@string/addItemButton"
android:scaleType="fitCenter"
android:src="@drawable/plus_add"
android:visibility="gone" />
</LinearLayout>
</LinearLayout>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:gravity="bottom|center_horizontal"
android:orientation="horizontal"
android:paddingLeft="16dp"
android:paddingRight="16dp" >

<ImageButton
android:id="@+id/syncListsButton"
android:layout_width="64dp"
android:layout_height="match_parent"
android:src="@android:drawable/ic_popup_sync" />

<ImageButton
android:id="@+id/showOrHide"
android:layout_width="64dp"
android:layout_height="match_parent" />

<ImageButton
android:id="@+id/delListButton"
android:layout_width="64dp"
android:layout_height="match_parent"
android:src="@android:drawable/ic_menu_delete" />
</LinearLayout>
</LinearLayout>


The "showOrHide" button shows/hides the "addListText"/"addTextListButton" combo.

When the EditText is shown for the first time and I touch it, the soft keyboard appears on the screen and the "addListText"/"addTextListButton" combo is panned correctly. When I hide the keyboard and then show it again, the keyboard covers completely my addListText editbox!

Any idea on what's going on? I'm testing it on Android 4.2.2.

Please help! Thanks :-)

edit: I've also tried to put the first LinearLayout inside a ScrollView but it doesn't work!

Answer

subclassed EditText and overridden the method onKeyPreIme(int keyCode, KeyEvent event) like this:

   @Override
   public boolean onKeyPreIme(int keyCode, KeyEvent event)
   {
      if(keyCode == KeyEvent.KEYCODE_BACK)
        {
            clearFocus();
        }
   return super.onKeyPreIme(keyCode, event);
   }

Now when the back key is pressed, the EditText lost the focus. Then tapping it again adjustpan will work.
