import android.widget.TabHost;
import android.widget.Toast;


public class MainActivity extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_main);这个一定要注释掉
        
        TabHost tabHost = getTabHost();//获取TabHost

        //获取视图
        LayoutInflater.from(this).inflate(R.layout.activity_main, tabHost.getTabContentView(), true);
        //通过布局的tab1 newTabSpec                     设置标题              设置图片
        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("美照1").setContent(R.id.tab01));
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("美照2").setContent(R.id.tab02));
        tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("美照3").setContent(R.id.tab03));

        tabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
            @Override
            public void onTabChanged(String tabId) {
                Toast.makeText(MainActivity.this, "你最美你最美你最美", Toast.LENGTH_SHORT).show();
            }
        });
