Android中使用TabHost实现类似标签栏的效果

MainActivity.java

public class MainActivity extends TabActivity { private TabHost tabHost;      @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.main);                      //加载底部Tab布局           LinearLayout tab1=(LinearLayout)LayoutInflater.from(this).inflate(R.layout.item, null);          final ImageView icon1=(ImageView)tab1.findViewById(R.id.icon);                 icon1.setBackgroundResource(R.drawable.icon11);          final TextView title1=(TextView)tab1.findViewById(R.id.title);          title1.setText("First");                   LinearLayout tab2=(LinearLayout)LayoutInflater.from(this).inflate(R.layout.item, null);          ImageView icon2=(ImageView)tab2.findViewById(R.id.icon);          icon2.setBackgroundResource(R.drawable.icon12);          TextView title2=(TextView)tab2.findViewById(R.id.title);          title2.setText("Second");                       // 加载TabSpec          /* tabHost = (TabHost) findViewById(R.id.view_tab_host);          tabHost.setup(getLocalActivityManager());  */        tabHost = getTabHost();                                 //tabHost.setup();          TabSpec ts1 = tabHost.newTabSpec("Activity1");          ts1.setIndicator(tab1);                ts1.setContent(new Intent(this, FirstActivity1.class));          tabHost.addTab(ts1);                TabSpec ts2 = tabHost.newTabSpec("Activity2");          ts2.setIndicator(tab2);                     ts2.setContent(new Intent(this, SecondActivity2.class));          tabHost.addTab(ts2);            //设置标签栏背景图片           TabWidget tw = tabHost.getTabWidget();          tw.setBackgroundResource(R.drawable.tabbarbg);                        }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }        }
