TabHost的使用

1. 从一个layout id创建各个tab页

[java] view plaincopy

1. public class Tabs1 extends TabActivity {  
2.     @Override  
3.     protected void onCreate(Bundle savedInstanceState) {  
4.         super.onCreate(savedInstanceState);  
5.         TabHost tabHost = getTabHost();  
6.           
7.         LayoutInflater.from(this).inflate(R.layout.tabs1, tabHost.getTabContentView(), true);  
8.         tabHost.addTab(tabHost.newTabSpec("tab1")  
9.                 .setIndicator("tab1")  
10.                 .setContent(R.id.view1));  
11.         tabHost.addTab(tabHost.newTabSpec("tab3")  
12.                 .setIndicator("tab2")  
13.                 .setContent(R.id.view2));  
14.         tabHost.addTab(tabHost.newTabSpec("tab3")  
15.                 .setIndicator("tab3")  
16.                 .setContent(R.id.view3));  
17.     }  
18. }  

 

 

2. 动态创建一个view来做为tab页的内容

[java] view plaincopy

1. public class Tabs2 extends TabActivity implements TabHost.TabContentFactory {  
2.     @Override  
3.     protected void onCreate(Bundle savedInstanceState) {  
4.         super.onCreate(savedInstanceState);  
5.         final TabHost tabHost = getTabHost();  
6.         tabHost.addTab(tabHost.newTabSpec("tab1")  
7.                 .setIndicator("tab1", getResources().getDrawable(R.drawable.star_big_on))  
8.                 .setContent(this));  
9.         tabHost.addTab(tabHost.newTabSpec("tab2")  
10.                 .setIndicator("tab2")  
11.                 .setContent(this));  
12.         tabHost.addTab(tabHost.newTabSpec("tab3")  
13.                 .setIndicator("tab3")  
14.                 .setContent(this));  
15.     }  
16.     /** {@inheritDoc} */  
17.     public View createTabContent(String tag) {  
18.         final TextView tv = new TextView(this);  
19.         tv.setText("Content for tab with tag " + tag);  
20.         return tv;  
21.     }  
22. }  

 

 

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。。。

[java] view plaincopy

1. public class Tabs3 extends TabActivity {  
2.     @Override  
3.     protected void onCreate(Bundle savedInstanceState) {  
4.         super.onCreate(savedInstanceState);  
5.         final TabHost tabHost = getTabHost();  
6.         tabHost.addTab(tabHost.newTabSpec("tab1")  
7.                 .setIndicator("list")  
8.                 .setContent(new Intent(this, List1.class)));  
9.         tabHost.addTab(tabHost.newTabSpec("tab2")  
10.                 .setIndicator("photo list")  
11.                 .setContent(new Intent(this, List8.class)));  
12.           
13.         // This tab sets the intent flag so that it is recreated each time  
14.         // the tab is clicked.  
15.         tabHost.addTab(tabHost.newTabSpec("tab3")  
16.                 .setIndicator("destroy")  
17.                 .setContent(new Intent(this, Controls2.class)  
18.                         .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));  
19.     }  
20. }
