标签使用

先上一下实现效果图：

public class tttab extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_tttab);
        setTitle("TabDemoActivity");
        TabHost tabHost = getTabHost();
        
        // 内容：采用布局文件中的布局
        LayoutInflater.from(this).inflate(R.layout.activity_tttab,
                tabHost.getTabContentView(), true);
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1")
                .setContent(R.id.view1));
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("tab2")
                .setContent(R.id.view2));
        tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3")
                .setContent(R.id.view3));

    }
}
