Android SearchView自动点击

Question

如何在搜索视图中输入自动？更确切地说.. 这就是我的全部 3 photos of my aplication。所以这是我的问题，在我进入我的应用程序之后，我按下了他在另一个屏幕上从第二张照片中输入的第一张照片中的搜索按钮，再次使用一个搜索按钮，我需要再次按下它才能真正进入搜索，第三张照片。如何从我的应用程序中删除第二张照片？我想要这样，在我按下第一张照片的搜索按钮后，我想自动进入第三张照片，而无需再次点击搜索按钮。

您需要打开操作视图。在 onPrepareOptionsMenu 的 SearchActivity 中添加描边

menu.findItem(R.id.action_search).expandActionView();
