在动作条动态更改图标 [英] Change icons in ActionBar dynamically

问题描述

我有其中有一个动作条的活动，但我需要动态地更改了动作条的图标，我有一个暂停和播放按钮，我需要的暂停按钮就可以了用户点击更换播放按钮。我已搜查，我发现它：

I have an Activity which has an ActionBar but I need to change the icons on the ActionBar dynamically, I have a pause and a play button and I need to replace the play button with the pause button as the user click on it. I have searched and I found it:

   @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        if(DEBUG) Log.i("onCreateOptionsMenu()", "onCreateOptionsMenu() -> LogicAnalizerView");

        //menu.add("").setIcon(R.drawable.pause).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.actionbarlogic, menu);
        menu.removeItem(R.id.pauseLogic);

        return true;
    }

因此​​，在这种方式，我删除了暂停按钮，我可以将其添加太多，但是当我开始了活动和动作条绘制它才会发生。我怎么可以强制重绘动作条？此外，在这条路上，整个动作条被重绘是这样吗？什么办法可以只重绘按钮/图标，我想要什么？

So in this way I remove the Pause button and I can add it too, but it only happen when I start the Activity and the ActionBar is drawn. How can I force to redraw the ActionBar? Also, on this way the whole ActionBar is redrawn is that right? Is any way to redraw only the button/icon i want?

感谢您：）
