推荐答案

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
