excellent work!I dump the view tree,found some layouts between decorView and contentView which are redundant.

private void initValue(Activity activity) {
this.activity = activity;
leftMenuItems = new ArrayList();
rightMenuItems = new ArrayList();
ignoredViews = new ArrayList();

    viewDecor = (ViewGroup) activity.getWindow().getDecorView();
    viewActivity = new TouchDisableView(this.activity);
    // View mContent = viewDecor.getChildAt(0);
    // viewDecor.removeViewAt(0);
    ViewGroup contentView = (ViewGroup) (viewDecor.findViewById(android.R.id.content));
    View mContent = contentView.getChildAt(0);
    contentView.removeAllViews();
    viewDecor.removeAllViews();

    viewActivity.setContent(mContent);
    addView(viewActivity);

    ViewGroup parent = (ViewGroup) scrollViewLeftMenu.getParent();
    parent.removeView(scrollViewLeftMenu);
    parent.removeView(scrollViewRightMenu);
}
