Android中TabHost部件使用

其效果图：

下面就是创建 Activity类 来实现 其功能：

public class MainActivity extends TabActivity {
	
	public TabHost tabHost;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// 获取对象
		tabHost = getTabHost();

		TabSpec nearby_tab = tabHost.newTabSpec("nearby_tab");

		TabSpec history_tab = tabHost.newTabSpec("history_tab");

		TabSpec about_tab = tabHost.newTabSpec("about_tab");

		nearby_tab.setIndicator("优酷首页",
				getResources().getDrawable(R.drawable.tab_home_selected))
				.setContent(new Intent(this, MyCenterActivity.class));

		history_tab.setIndicator("频道中心",
				getResources().getDrawable(R.drawable.tab_category_selected))
				.setContent(new Intent(this, MyIndexActivity.class));

		about_tab.setIndicator("个人中心",
				getResources().getDrawable(R.drawable.tab_usercenter_select))
				.setContent(new Intent(this, MySelfActivity.class));

		tabHost.addTab(nearby_tab);

		tabHost.addTab(history_tab);

		tabHost.addTab(about_tab);

	}

	@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;
	}

}
