我有一个活动名称“标签”。它启动 4 个不同的选项卡,每个选项卡都有自己的活动。它用 :

th = (TabHost) findViewById(R.id.tabhost);
    th.setup(this.getLocalActivityManager());
    TabSpec specs = th.newTabSpec("Tag1");
    Intent tabSelection = new Intent (this, ProfileSettings.class);

    tabSelection.putExtras(gotSettings);
    specs.setContent(tabSelection);
    specs.setIndicator("Settings",
            getResources().getDrawable(R.drawable.ic_menu_friendslist));
    th.addTab(specs);

    specs = th.newTabSpec("Tag2");
    tabSelection = new Intent (this,InternationalRoamingService.class);
    specs.setContent(tabSelection);
    specs.setIndicator("IRS", getResources().getDrawable(R.drawable.ic_menu_mapmode));
    th.addTab(specs);

    specs = th.newTabSpec("Tag3");
    tabSelection = new Intent (this,Call.class);
    specs.setContent(tabSelection);
    specs.setIndicator("Call", getResources().getDrawable(R.drawable.call));
    th.addTab(specs);

    specs = th.newTabSpec("Tag4");
    tabSelection = new Intent (this,WebSMS.class);
    specs.setContent(tabSelection);
    specs.setIndicator("SMS", getResources().getDrawable(R.drawable.ic_menu_start_conversation));
    th.addTab(specs);

我将包“gotSettings”从父级传递给子级没有问题。但是如何从子活动更新捆绑包的值或将值从子活动传递给父?
