切换到其他活动时是否让活动在后台运行?
我要进行主要活动，而按钮要进行其他活动.当我去其他活动时，我的主要活动停止了.我将如何进行主要活动?
I have my main activity going and a button going to a different activity. When I go to the other activity my main activity stops. How would I keep the main activity going?
谢谢.
是的，您可以保持主活动运行.我的方法是使用"CHEAT".
Yes, you can keep your main Activity running. My way is use a "CHEAT".
例如，您的主要活动是A，在A中，我们有按钮btnA.单击此btnA将打开活动B.
Example your main Activity is A, in A we have button btnA. Click this btnA will open activity B.
您创建的标签栏包含2个包含A和B的标签.初始化标签栏后，调用
You create a tab bar with 2 tab contains A and B. After initialize tab bar, call
tabHost.getTabWidget.setVisibility(View.GONE);
隐藏该标签.因此，您只会看到可见的主活动.
to hide this tab. So you only see main Activity visible.
单击btnA时，只需将tabHost切换为B
When btnA is clicked, only need to switch tabHost to B
tabHost.setCurrentTab(1);//1 is index of Activity B
