Tab選項卡+實例

系統 1725 0

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. ?

Tab選項卡+實例

?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" ?
