调用完成（）在Android的活动实际上并没有完成 [英] Calling finish() on an Android activity doesn't actually finish

问题描述

我打电话完成（），但我的活动不断前进。

I'm calling finish() but my activity keeps on going.

我是从主要活动画面的菜单调用的活动。在我的活动的的onCreate（）方法，我有以下的code片段：

I have an activity which is invoked by a menu from the main activity screen. In my activity's onCreate() method I have the following code fragment:

    // Make sure there are some events in the list.
    if (theEventArrayList.isEmpty()){
        Toast.makeText(this, "Event List is empty", Toast.LENGTH_LONG).show();
        finish();
    }
    SummarizeCurrentEvent();
    graphEvents();

如果该列表是空的搭设的面包，我可​​以在调用完成设置断点（）。如果我从在调试步骤它去直接 SummarizeCurrentEvent（）。我以为完成（）将退出该活动。这是不是这样的？我在哪里可以找到有关该方法的详细信息？

If the list is empty it puts up the Toast, and I can set breakpoint on the call to finish(). If I step from that in the debugger it goes to straight to SummarizeCurrentEvent(). I thought finish() would exit the activity. Is this not the case? Where can I find out more information about this method?

推荐答案

您应该把返回的完成后声明，因为那个叫完成将被完全执行，否则

You should put a return statement after that finish, because the method that called finish will be executed completely otherwise.
