mt6735 在Music中长按一首歌，执行"添加到播放列表"时，屏幕会闪两次

[DESCRIPTION]
在Music中，长按一首歌，在弹出的菜单中执行“添加到播放列表”菜单此时屏幕会闪两次
[SOLUTION]
請將 PhoneWindow.DialogMenuCallback 裡所有的用到 mSubMenuHelper 註釋掉, 就可以解決這個問題
詳細修改如下
private final class DialogMenuCallback implements MenuBuilder.Callback,
MenuPresenter.Callback {
private int mFeatureId;
//private MenuDialogHelper mSubMenuHelper;
public DialogMenuCallback(int featureId) {
mFeatureId = featureId;
}
public void onCloseMenu(MenuBuilder menu, boolean allMenusAreClosing) {
if (menu.getrootMenu() ！= menu) {
onCloseSubMenu(menu);
}
if (allMenusAreClosing) {
Callback callback = getCallback();
if (callback ！= null && ！isDestroyed()) {
callback.onPanelClosed(mFeatureId, menu);
}
if (menu == mContextMenu) {
dismissContextMenu();
}
// Dismiss the submenu, if it is showing
//if (mSubMenuHelper ！= null) {
// mSubMenuHelper.dismiss();
// mSubMenuHelper = null;
//}
}
}
public void onCloseSubMenu(MenuBuilder menu) {
Callback callback = getCallback();
if (callback ！= null && ！isDestroyed()) {
callback.onPanelClosed(mFeatureId, menu.getRootMenu());
}
}
public boolean onMenuItEMSelected(MenuBuilder menu, MenuItem item) {
Callback callback = getCallback();
return (callback ！= null && ！isDestroyed())
&& callback.onMenuItemSelected(mFeatureId, item);
}
public void onMenuModeChange(MenuBuilder menu) {
}
public boolean onOpenSubMenu(MenuBuilder subMenu) {
if (subMenu == null) return false;
// Set a SIMple callback for the submenu
subMenu.setCallback(this);
// M: ListMenuPresenter create sub menu dialog there
// The window manager will give us a valid window token
//mSubMenuHelper = new MenuDialogHelper(subMenu);
//mSubMenuHelper.show(null);
return true;
}
}
