Implementation of the "Android" tab page, using Tabhost

The first step, the layout file

<?xml version= "1.0" encoding= "Utf-8"? ><tabhost xmlns:android= "Http://schemas.android.com/apk/res/android "Android:layout_width=" match_parent "android:layout_height=" match_parent "android:id=" @android: Id/tabhost "&     Gt <linearlayout android:layout_width= "match_parent" android:layout_height= "match_parent" android:orientation= "V        Ertical "> <include layout=" @layout/top "/> <tabwidget android:layout_width=" Match_parent " android:layout_height= "Wrap_content" android:id= "@android: Id/tabs" ></TabWidget> <fra        Melayout android:layout_width= "match_parent" android:layout_height= "0DP" android:layout_weight= "1" Android:id= "@android: Id/tabcontent" > <linearlayout android:layout_width= "match_pare NT "android:layout_height=" Match_parent "android:id=" @+id/lkgj "android:background=" #ffff FF "Android:orientation= "vertical" android:layout_gravity= "center" > <textview an Droid:layout_width= "250DP" android:layout_height= "wrap_content" android:layout_margintop= "30 DP "android:layout_gravity=" center "android:textsize=" 20DP "android:text=" @st Ring/gjtext "/> <edittext android:layout_width=" 280DP "Android                oid:layout_height= "40DP" android:id= "@+id/lkgjipedittext" android:layout_margintop= "10DP"                  android:layout_gravity= "Center" android:singleline= "true" android:hint= "Please enter IP address" Android:textsize= "15dip" android:textcolorhint= "#AAAAAA" android:layout_margin= "20dip" android:padding= "5dip" android:background= "@drawable/shape" Andro     Id:inputtype= "Text"            /> <button android:id= "@+id/lkgjbtn" android:layout_width= "250d P "android:layout_height=" 80DP "android:layout_gravity=" center "android:layou t_margintop= "40DP" android:text= "@string/lkgjbtn"/> </LinearLayout> &lt ; LinearLayout android:layout_width= "match_parent" android:layout_height= "Match_parent" an            Droid:id= "@+id/dsgj" android:background= "#ffffff" android:orientation= "vertical" >                <textview android:layout_width= "250DP" android:layout_height= "Wrap_content" android:layout_margintop= "30DP" android:layout_gravity= "center" android:textsize= "20DP" android:text= "@string/gjtext"/> <edittext android:l    Ayout_width= "280DP"            android:layout_height= "40DP" android:id= "@+id/dsgjedittext" Android:layout_margi ntop= "10DP" android:layout_gravity= "center" android:singleline= "true" android:hint= "Please enter IP Address "android:textsize=" 15dip "android:textcolorhint=" #AAAAAA "Android:                  Layout_margin= "20dip" android:padding= "5dip" android:background= "@drawable/shape" android:inputtype= "text"/> <edittext android:layout_width= "280d P "android:layout_height=" 40DP "android:id=" @+id/gjdateedittext "Android:layo ut_gravity= "Center" android:singleline= "true" android:hint= "Please enter the number of seconds" android:textsize= " 15dip "android:textcolorhint=" #AAAAAA "android:layout_margin=" 20dip "an    Droid:padding= "5dip"            android:background= "@drawable/shape" android:inputtype= "number"/>            <relativelayout android:layout_width= "match_parent" android:layout_height= "Match_parent"            Android:background= "#ffffff" android:orientation= "vertical" android:layout_gravity= "center" android:gravity= "center" > <button android:layout_width= "150DP" android:layout_height= "80DP" android:id= "@+id/dsgjbtn" android:text= "                 @string/dsgjbtn "android:layout_margintop=" 2DP "/> <button Android:layout_width= "150DP" android:layout_height= "80DP" android:id= "@+id/qxgjb TN "android:layout_torightof=" @+id/dsgjbtn "android:text=" @string/qxgjbtn "an Droid:layout_margintop= "2DP "/> </RelativeLayout> </LinearLayout> & Lt;/framelayout></linearlayout></tabhost>

Step two, initialize the Tabhost

Defining variables at the top

Private Tabhost Tabhost;

In the OnCreate method

From Tabactivity, get the Tabhosttabhost = Gettabhost () of the tab, Tabhost.addtab (Tabhost.newtabspec ("one"). Setindicator (" Shut down immediately "). SetContent (R.ID.LKGJ)); Tabhost.addtab (tabhost//Create a new label One.newtabspec (" both ")//Set the label caption. Setindicator (" timed off ")/ /sets the layout content of the label. SetContent (R.ID.DSGJ));//Click event Tabhost.setontabchangedlistener (New Ontabchangelistener () {<span  Style= "White-space:pre" ></span> @Override <span style= "White-space:pre" ></span> public void ontabchanged (String tabId) {<span style= "white-space:pre" ></span> <span style= "White-spa Ce:pre "></span>} <span style=" White-space:pre "></span>});
