Tab与TabHost转

第一种:继承TabActivity,从TabActivity中用getTabHost()方法获取TabHost。只要定义具体Tab内容布局就行了.

  36.     </LinearLayout>  
  37. </FrameLayout>

  39. java代码:  
  40. super.onCreate(savedInstanceState);  
  41.         myTabhost=this.getTabHost();  
  42.         //get Tabhost  
  43.         LayoutInflater.from(this).inflate(R.layout.main, myTabhost.getTabContentView(), true);  
  44.         myTabhost.setBackgroundColor(Color.argb(1502270150));  
  45.           
  46.         myTabhost  
  47.                 .addTab(myTabhost.newTabSpec("One")// make a new Tab  
  48.                         .setIndicator("A")  
  49.                         // set the Title and Icon  
  50.                         .setContent(R.id.widget_layout_Blue));  
  51.         // set the layout  
  52.   
  53.         myTabhost  
  54.                 .addTab(myTabhost.newTabSpec("Two")// make a new Tab  
  55.                         .setIndicator("B",  
  56.                                 getResources().getDrawable(R.drawable.mumule))  
  57.                         // set the Title and Icon  
  58.                         .setContent(R.id.widget_layout_green));  
  59.         // set the layout  
  60.   
  61.         myTabhost  
  62.                 .addTab(myTabhost.newTabSpec("Three")// make a new Tab  
  63.                         .setIndicator("C",  
  64.                                 getResources().getDrawable(R.drawable.notepad))  
  65.                         // set the Title and Icon  
  66.                         .setContent(R.id.widget_layout_red));  



第二种:不用继承TabActivity,在布局文件中定义TabHost即可,但是TabWidget的id必须是
@android:id/tabs,FrameLayout的id必须是@android:id/tabcontent。TabHost的id可以自定义.
