By many days spent,I found a solution. It is a hack.

put you edittext wrapped in linearlayout.

detect softkeyboard show by visiable layout change.

 public final void setKeyboardListener(final OnKeyboardVisibilityListener listener) {   final View activityRootView = getWindow().getDecorView()     .findViewById(android.R.id.content);      activityRootView.getViewTreeObserver()     .addOnGlobalLayoutListener(new OnGlobalLayoutListener() {        private final Rect r = new Rect();       private boolean wasOpened;        @Override       public void onGlobalLayout() {         activityRootView.getWindowVisibleDisplayFrame(r);          int heightDiff = activityRootView.getRootView().getHeight()             - (r.bottom - r.top);         boolean isOpen = heightDiff > 100;          if (isOpen == wasOpened) {           return;         }          wasOpened = isOpen;         listener.onVisibilityChanged(isOpen);       }     });    }    public interface OnKeyboardVisibilityListener {     void onVisibilityChanged(boolean visible);     }

when the softkeyboard show,pick up a textview in listview item or expandablelistview child item. then set it text for any thing, the whole view scrolled as normal! code like this:

activity.setKeyboardListener(new OnKeyboardVisibilityListener() {   @Override public void onVisibilityChanged(boolean visible) { if (visible) {   Message message = new Message();   message.what = 999;   handler.sendMessage(message);   }  } }); private Handler handler = new Handler() {  @Override public void handleMessage(Message msg) { if (msg.what == 999) {   if (mDataMap.size() > 0) {   for (int i = 0; i < expandablelistview.getChildCount(); i++) {     View v = expandablelistview.getChildAt(i);     TextView tvCannotSee = (TextView) v.findViewById(R.id.tv_cannot_see );     if (tvCannotSee != null) {       //this is the key hack to make adjuspan work! and scroll the whole view up as normal       tvCannotSee.setText("this is an android bug");       return;       }     }    }    return;   }  super.handleMessage(msg);  } };

this textview show invisble to user for proper purpose.if it is a expandablelistview and the edittext in childitem,the textview update must be in a childitem.

I also faced the same issue, but after googling the issue for some time i ended up the problem as below.

1) Add android:windowSoftInputMode="adjustPan" tag inside activity of manifest file

    <activity         android:name=".MainActivity"         android:configChanges="locale|keyboardHidden|orientation|screenSize|layoutDirection|screenLayout"         android:screenOrientation="portrait"         android:windowSoftInputMode="stateHidden|adjustResize|adjustPan"></activity>

2) add android:descendantFocusability="beforeDescendants" attribute to your expandable listview as below.

    <ExpandableListView                 android:id="@android:id/list"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:layout_above="@+id/textDate"                 android:layout_below="@+id/relativeLayout2"                 android:descendantFocusability="beforeDescendants"                 android:layout_margin="@dimen/margin_meium"                 android:groupIndicator="@android:color/transparent" />
