如何解决我的应用程序在Honeycomb上启动了两次

| 当我在Honeycomb上执行我的应用程序时，它将启动两次。 我在onActivate的onCreate（）方法中放置了一个断点，尽管只有一个正在运行的进程，但调试器在断点处停止了两次，并且我的平板电脑上运行了两个可见的应用程序，一个在另一个后面。 有人在蜂窝中遇到这样的事情吗？有见识吗？ 这是日志，请注意有关两次调用LoadingActivity.OnCreate（）的注意。

解决方法

您的应用是否仅限纵向模式，并且正在平板电脑（默认为横向）上运行，如果是这样，这就是原因。     ,我正在使用带有键盘底座的Asus Eee Pad Transformer进行开发。我注意到，当您在添加了OnEditorActionListener（）的窗体上按Enter时，它将被调用两次！ 
    etPassWord.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v,int actionId,KeyEvent event) {
            if (!clickedIme) {
                clickLogIn();
                clickedIme = true;
            }
            return true;
        }
    });
因此，我添加了
clickedIme
布尔标志来抑制第二个
clickLogIn()
调用。请注意，如果
clickedIme
失败，则必须将其重置为false，因此您无需再压入Enter键。
