Dialog如何覆盖状态栏全屏显示

Component component = LayoutScatter.getInstance(context).parse(ResourceTable.Layout_layout_dialog, null, false);
Button button = (Button) component.findComponentById(ResourceTable.Id_btn_close);
button.setClickedListener(new Component.ClickedListener() {
    @Override
    public void onClick(Component component) {
        commonDialog.destroy();
    }
});

commonDialog.setSize(ComponentContainer.LayoutConfig.MATCH_PARENT, ComponentContainer.LayoutConfig.MATCH_PARENT);
commonDialog.setContentCustomComponent(component);
commonDialog.setTransparent(true);
commonDialog.setAlignment(LayoutAlignment.TOP);
commonDialog.siteKeyboardCallback(new IDialog.KeyboardCallback() {
    @Override
    public boolean clickKey(IDialog iDialog, KeyEvent keyEvent) {
        return true;
    }
});

commonDialog.show();
