来电onSearchRequested（）在处理搜索请求相同的活动方法导致重复的活动栈 [英] Call to method onSearchRequested() in the same activity that handles search requests causes duplication in activity stack

问题描述

我有与SearchManager的处理搜索请求的活动，它的工作就好了。让我们把这个活动MySearchActivity.java。问题是，这次活动中，我有一个按钮，即与onSearchRequested（）。

I have an activity that handles search requests with the SearchManager and it's working just fine. Let's call this activity MySearchActivity.java. The problem is that within this activity, I have a button that invokes the search request dialog with a call to onSearchRequested().

如果MySearchActivity.java是在活动堆栈中的当前任务和用户水龙头这个活动调用onSearchRequested（内的图标），本次活动是在其本身上再次推出。所以活动叠层内，我有两个相同的活动对彼此的顶部上。

If MySearchActivity.java is the current task in the activity stack and the user taps the icon within this activity that calls onSearchRequested(), this activity is re-launched on top of itself. So within the activity stack, I have two of the same activities on top of each other.

我不希望使用Android：noHistory在清单这项活动，并不能找到任何其他合适的标志想什么，我完成

I don't want to use android:noHistory in the manifest for this activity, and can't find any other suitable flags for what I'd like to accomplish.

我想，如果用户点击在MySearchActivity.java它调用调用onSearchRequested（），该活动不重复自己在堆栈中。图标

I would like that if the user taps the icon in MySearchActivity.java which invokes the call to onSearchRequested(), that the activity not duplicate itself in the stack.

我知道我可能忽视的东西或使这个复杂得多，它确实是....任何想法？

I know I'm probably overlooking something or making this more complicated than it really is....any ideas?

推荐答案

有关你可能需要设置启动模式解决singleTop的活动（例如机器人：launchMode =singleTop）。下面是进一步explenation @ 文档。祝你好运！

For the solution you probably have to set launch mode to "singleTop" for activity (e.g android:launchMode="singleTop"). Here is the further explenation @documentation. Good luck!
