Tab選項卡是一個非常方便的組件。

一.使用Tab組件的步驟：

1.在布局文件中使用FrameLayout列出Tab組件以及Tab中的內容組件

2. Activity要繼承TabActivity

3.調用TabActivity的getTabHost( )方法來獲得TabHost對象

4.通過TabHost創建Tab選項

二.實現不同Tab里面的內容有兩種方式：

1.切換不同的Tab時候，不同Tab里面的內容在同一個Activity顯示，主要是通過修改布局文件里面的id來實現的。下面是一個具體的例子：

MainActivity.java

1. package ?com.android.tab.activity; ?
2. ?
3. import ?android.app.TabActivity; ?
4. import ?android.os.Bundle; ?
5. import ?android.view.LayoutInflater; ?
6. import ?android.widget.TabHost; ?
7. ?
8. public ? class ?MainActivity? extends ?TabActivity?{ ?
9. ???? @Override ?
10. ???? public ? void ?onCreate(Bundle?savedInstanceState)?{ ?
11. ???????? super .onCreate(savedInstanceState); ?
12. ????????? //獲得TabHost對象????? ?
13. ????????TabHost?tah?=?getTabHost(); ?
14. ???????? ?
15. ???????? //?from(this)從TabActivity獲取LayoutInflater ?
16. ???????? //?R.layout.main?存放Tab布局 ?
17. ???????? //?通過TabHost獲得存放Tab標簽頁內容的FrameLayout ?
18. ???????? //?是否將inflate?加到根布局元素上 ?
19. ????????LayoutInflater.from( this ).inflate(R.layout.main,?tah.getTabContentView(),? true ); ?
20. ???????? ?
21. ???????? //設置Tab標簽的內容和顯示內容 ?
22. ????????tah.addTab(tah.newTabSpec( "tab1" ).setIndicator( "圖片1" ).setContent(R.id.TextView01)); ?
23. ????????tah.addTab(tah.newTabSpec( "tab2" ).setIndicator( "圖片2" ).setContent(R.id.TextView02)); ?
24. ????????tah.addTab(tah.newTabSpec( "tab3" ).setIndicator( "圖片3" ).setContent(R.id.TextView03));?????????????????????? ?
25. ????} ?
26. }?

main.xml

1. <? xml ? version = "1.0" ? encoding = "utf-8" ?> ?
2. < FrameLayout ? xmlns:android = "http://schemas.android.com/apk/res/android" ?
3. ???? android:id = "@+id/FrameLayout01" ? ?
4. ???? android:layout_width = "wrap_content" ? ?
5. ???? android:layout_height = "wrap_content" ?
6. ???? > ??? ?
7. ???? < TabHost ? ?
8. ???????? android:id = "@+id/TabHost01" ?
9. ???????? android:layout_width = "wrap_content" ? ?
10. ???????? android:layout_height = "wrap_content" ? ?
11. ???????? /> ?
12. ???? < TextView ? ?
13. ???????? android:id = "@+id/TextView01" ? ?
14. ???????? android:background = "@drawable/pic1" ?
15. ???????? android:layout_width = "wrap_content" ? ?
16. ???????? android:layout_height = "wrap_content" ? ?
17. ???????? /> ?? ?
18. ???? < TextView ? ?
19. ???????? android:id = "@+id/TextView02" ? ?
20. ???????? android:background = "@drawable/pic2" ?
21. ???????? android:layout_width = "wrap_content" ? ?
22. ???????? android:layout_height = "wrap_content" ? ?
23. ???????? /> ?? ?
24. ???? < TextView ? ?
25. ???????? android:id = "@+id/TextView03" ? ?
26. ???????? android:background = "@drawable/pic3" ?
27. ???????? android:layout_width = "wrap_content" ? ?
28. ???????? android:layout_height = "wrap_content" ? ?
29. ???????? /> ?? ?
30. </ FrameLayout > ?
31. ?
32. ?

效果圖：

?1.切換不同的Tab時候，不同Tab里面的內容在不同的Activity顯示

?先創建三個類FirstActivity.java，SecondActivity.java，ThirdActivity.java，都是繼承Activity

FirstActivity.java

1. package ?com.android.tabtest.activity; ?
2. ?
3. import ?android.app.Activity; ?
4. import ?android.os.Bundle; ?
5. import ?android.widget.TextView; ?
6. ?
7. public ? class ?FirstActivity? extends ?Activity?{ ?
8. ???? public ? void ?onCreate(Bundle?savedInstanceState)?{ ?
9. ??????? super .onCreate(savedInstanceState); ?
10. ???????TextView?textview?=? new ?TextView( this ); ?
11. ???????textview.setText( "這是Tab1" ); ?
12. ???????setContentView(textview); ?
13. ????} ?
14. } ?

SecondActivity.java

1. package ?com.android.tabtest.activity; ?
2. ?
3. import ?android.app.Activity; ?
4. import ?android.os.Bundle; ?
5. import ?android.widget.TextView; ?
6. ?
7. public ? class ?SecondActivity? extends ?Activity?{ ?
8. ???? public ? void ?onCreate(Bundle?savedInstanceState)?{ ?
9. ???????? super .onCreate(savedInstanceState); ?
10. ????????TextView?textview?=? new ?TextView( this ); ?
11. ????????textview.setText( "這是Tab2" ); ?
12. ????????setContentView(textview); ?
13. ????} ?
14. ?
15. } ?

ThirdActivity.java

1. package ?com.android.tabtest.activity; ?
2. ?
3. import ?android.app.Activity; ?
4. import ?android.os.Bundle; ?
5. import ?android.widget.TextView; ?
6. ?
7. public ? class ?ThirdActivity? extends ?Activity?{ ?
8. ???? public ? void ?onCreate(Bundle?savedInstanceState)?{ ?
9. ??????????? super .onCreate(savedInstanceState); ?
10. ???????????TextView?textview?=? new ?TextView( this ); ?
11. ???????????textview.setText( "這是Tab3" ); ?
12. ???????????setContentView(textview); ?
13. ????????} ?
14. ?
15. } ?

在layout文件夾中對main.xml進行修改

1. <? xml ? version = "1.0" ? encoding = "utf-8" ?> ?
2. < TabHost ? android:id = "@android:id/tabhost" ? android:layout_width = "fill_parent" ?
3. ???? android:layout_height = "fill_parent" ? xmlns:android = "http://schemas.android.com/apk/res/android" > ?
4. ???? < LinearLayout ?
5. ???????? android:orientation = "vertical" ?
6. ???????? android:layout_width = "fill_parent" ?
7. ???????? android:layout_height = "fill_parent" ?
8. ???????? > ?
9. ???????? < TabWidget ? ?
10. ???????????? android:id = "@android:id/tabs" ?
11. ???????????? android:layout_width = "fill_parent" ? ?
12. ???????????? android:layout_height = "wrap_content" ?
13. ???????????? /> ?
14. ???????? < FrameLayout ?
15. ???????????? android:id = "@android:id/tabcontent" ?
16. ???????????? android:layout_width = "fill_parent" ?
17. ???????????? android:layout_height = "fill_parent" ?
18. ???????????? android:padding = "5dp" ? ?
19. ???????????? /> ?
20. ???? </ LinearLayout > ?
21. </ TabHost > ?

新建一個測試Tab的類TabDemo.java，繼承于TabActivity類

1. package ?com.android.tabtest.activity; ?
2. ?
3. import ?android.app.TabActivity; ?
4. import ?android.content.Intent; ?
5. import ?android.content.res.Resources; ?
6. import ?android.os.Bundle; ?
7. import ?android.widget.TabHost; ?
8. import ?android.widget.TabHost.TabSpec; ?
9. ? ?
10. public ? class ?TabDemo? extends ?TabActivity?{ ?
11. ???? /**?Called?when?the?activity?is?first?created.?*/ ?
12. ???? @Override ?
13. ???? public ? void ?onCreate(Bundle?savedInstanceState)?{ ?
14. ???????? super .onCreate(savedInstanceState); ?
15. ????????setContentView(R.layout.main); //這里使用了上面創建的xml文件（Tab頁面的布局） ?
16. ????????Resources?res?=?getResources();? //?Resource?object?to?get?Drawables ?
17. ????????TabHost?tabHost?=?getTabHost();?? //?The?activity?TabHost ?
18. ????????TabSpec?spec; ?
19. ????????Intent?intent;?? //?Reusable?Intent?for?each?tab ?
20. ? ?
21. ?????? //第一個Tab ?
22. ??????? ?intent?=? new ?Intent( this ,FirstActivity. class ); //新建一個Intent用作Tab1顯示的內容 ?
23. ????????spec?=?tabHost.newTabSpec( "tab1" ) //新建一個?Tab ?
24. ???????? .setIndicator ( "Tab1" ,?res.getDrawable(android.R.drawable.ic_media_play)) //設置名稱以及圖標 ?
25. ??????? ?.setContent (intent); //設置顯示的intent，這里的參數也可以是R.id.xxx ?
26. ????????tabHost.addTab(spec); //添加進tabHost ?
27. ? ?
28. ???????? //第二個Tab ?
29. ????????intent?=? new ?Intent( this ,SecondActivity. class ); //第二個Intent用作Tab1顯示的內容 ?
30. ????????spec?=?tabHost.newTabSpec( "tab2" ) //新建一個?Tab ?
31. ????????.setIndicator( "Tab2" ,?res.getDrawable(android.R.drawable.ic_menu_edit)) //設置名稱以及圖標 ?
32. ????????.setContent(intent); //設置顯示的intent，這里的參數也可以是R.id.xxx ?
33. ????????tabHost.addTab(spec); //添加進tabHost ?
34. ???????? ?
35. ??????? //第三個Tab ?
36. ????????intent?=? new ?Intent( this ,SecondActivity. class ); //第二個Intent用作Tab1顯示的內容 ?
37. ????????spec?=?tabHost.newTabSpec( "tab2" ) //新建一個?Tab ?
38. ????????.setIndicator( "Tab3" ,?res.getDrawable(android.R.drawable.ic_menu_help)) //設置名稱以及圖標 ?
39. ????????.setContent(intent); //設置顯示的intent，這里的參數也可以是R.id.xxx ?
40. ????????tabHost.addTab(spec); //添加進tabHost ?
41. ? ?
42. ????????tabHost.setCurrentTab( 0 ); //設置當前的選項卡,這里為Tab1 ?
43. ????}? ?
44. }?

在AndroidManifest.xml里加入9~29行的聲明代碼

1. <? xml ? version = "1.0" ? encoding = "utf-8" ?> ?
2. < manifest ? xmlns:android = "http://schemas.android.com/apk/res/android" ?
3. ?????? package = "com.android.tabtest.activity" ?
4. ?????? android:versionCode = "1" ?
5. ?????? android:versionName = "1.0" > ?
6. ???? < uses-sdk ? android:minSdkVersion = "10" ? /> ?

8. ???? < application ? android:icon = "@drawable/icon" ? android:label = "@string/app_name" > ?
9. ???? < activity ? android:name = ".TabDemo" ?
10. ?????????????????? android:label = "@string/app_name" > ?
