Character encoding conversion under Windows

Sometimes people use tabhost+ other implementations of the demo. How to use tabhost simply?

Let's look at the example below:

public class Mainactivity extends tabactivity {public tabhost tabhost; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate);//Get Object tabhost = Gettabhost (); Tabhost.addtab ( Tabhost.newtabspec ("index"). Setindicator ("Real-time News"). SetContent (New Intent (this, indexactivity.class))); Tabhost.addtab (Tabhost.newtabspec ("center"). Setindicator ("My Space"). SetContent (New Intent (This, Middleactivity.class)); Tabhost.addtab (Tabhost.newtabspec ("Self"). Setindicator ("Settings"). SetContent (New Intent (this , Lastactivity.class)));//The current tab//specified by index specifies the index starting from 0//which page to display at the beginning Tabhost.setcurrenttab (0); Zero-based} @Overridepublic boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action Bar if It is Present.getmenuinflater (). Inflate (R.menu.main, menu); return true;}}

(2) Tabhost tab at the bottom of the example

With the LinearLayout layout, you can set the weight property to place the tab at the bottom

1. XML layout file

<?xml version= "1.0" encoding= "Utf-8"? ><tabhost xmlns:android= "Http://schemas.android.com/apk/res/android "Android:id=" @+id/tabhost "android:layout_width=" fill_parent "android:layout_height=" Fill_parent "Android:bac Kground= "@android: Color/white" android:orientation= "vertical" > <linearlayout android:layout_width= "Mat            Ch_parent "android:layout_height=" match_parent "android:orientation=" vertical "> <framelayout Android:id= "@android: Id/tabcontent" android:layout_width= "Fill_parent" Android:layout_heig ht= "0dip" android:layout_weight= "1.0" > </FrameLayout> <tabwidget android:        Id= "@android: Id/tabs" android:layout_width= "match_parent" android:layout_height= "Wrap_content" > </TabWidget> </LinearLayout></TabHost>

2, Mainactivity

public class Mainactivity extends activitygroup{private tabhost mtabhost;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main);    Inittabs ();        } private void Inittabs () {mtabhost = (tabhost) Findviewbyid (r.id.tabhost);                Mtabhost.setup (This.getlocalactivitymanager ());        Intent Intent = new Intent (this, homepageactivity.class); Mtabhost.addtab (Mtabhost.newtabspec ("Tab1"). Setindicator (GetString (r.string.homepage_indicator), Getresour               CES (). getdrawable (R.drawable.homepage_indicator_selector)). SetContent (intent));        Intent = new Intent (this, billboardactivity.class); Mtabhost.addtab (Mtabhost.newtabspec ("Tab2"). Setindicator (GetString (r.string.billboard_indicator), Getresou   RCEs (). getdrawable (R.drawable.billboard_indicator_selector)). SetContent (intent));             Intent = new Intent (this, mylotteryactivity.class); Mtabhost.addtab (Mtabhost.newtabspec ("Tab3"). Setindicator (GetString (r.string.mylottery_indicator), Getresou                RCEs (). getdrawable (R.drawable.mylottery_indicator_selector)). SetContent (intent));        Intent = new Intent (this, moreactivity.class); Mtabhost.addtab (Mtabhost.newtabspec ("Tab4"). Setindicator (GetString (R.string.more_indicator), Getresources (    ). Getdrawable (R.drawable.more_indicator_selector)). SetContent (intent)); }}
