Android：使用TabHost以编程方式创建View

Question

I want to create tabs which will show certain views I create through code. Now I can pass a View to TabHost, but only by id.

So I tried to assign some random id, say 1001 to my programmatically created view -

TabHost th = getTabHost();
View v=getMyView(); v.setId(1001);
th.addTab(th.newTabSpec("tab1").setIndicator("Monthly").setContent(v.getId()));

I get a Forced Close when I run this with the message that there is no view number 1001.

Is there any other way I can use my own generated views in TabHost, or a tabbed interface?

You need to use the version of the overloaded setContent() method that takes a TabHost.TabContentFactory .

th.addTab(th.newTabSpec("tab1")
    .setIndicator("Monthly")
    .setContent(new TabHost.TabContentFactory() {
        @Override
        public View createTabContent(String tag) {
            if (tag.equals("tab1")) {
                return getMyView();
            }
            return null;
        }));
