Android学习笔记-TabHost选项卡使用

在Android应用中，经常会用到TabHost选项卡，这里借花献佛，把apiDemo例子中的使用方法列举出来，，，

常用的方法有三种：

1. 从一个layout id创建各个tab页

public class Tabs1 extends TabActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); LayoutInflater.from(this).inflate(R.layout.tabs1, tabHost.getTabContentView(), true); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("tab1") .setContent(R.id.view1)); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("tab2") .setContent(R.id.view2)); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("tab3") .setContent(R.id.view3)); } } 

 

2. 动态创建一个view来做为tab页的内容

public class Tabs2 extends TabActivity implements TabHost.TabContentFactory { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("tab1", getResources().getDrawable(R.drawable.star_big_on)) .setContent(this)); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("tab2") .setContent(this)); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("tab3") .setContent(this)); } /** {@inheritDoc} */ public View createTabContent(String tag) { final TextView tv = new TextView(this); tv.setText("Content for tab with tag " + tag); return tv; } } 

 

3. 传递一个intent来传递参数，并以新启动的activity做为tab页的内容，这个应该是比较方便传递参数的。。。

public class Tabs3 extends TabActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("list") .setContent(new Intent(this, List1.class))); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("photo list") .setContent(new Intent(this, List8.class))); // This tab sets the intent flag so that it is recreated each time // the tab is clicked. tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("destroy") .setContent(new Intent(this, Controls2.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))); } }
