Android Custom Tabhost,tabwidget Style

Interface is relatively simple, want to do a good job to change a few pictures can be.

The first step is to put the tabhost in the layout (which is generated automatically when Main.xml is created), as long as the Tabhost control is placed on the screen:

<?XML version= "1.0" encoding= "Utf-8"?><Tabhostxmlns:android= "Http://schemas.android.com/apk/res/android"Android:id= "@+id/taskdescribe_buildingmeter_tabhost"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"Android:background= "@color/white" >    <LinearLayoutAndroid:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical">                <TabwidgetAndroid:id= "@android: Id/tabs"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content">          </Tabwidget>        <FramelayoutAndroid:id= "@android: Id/tabcontent"Android:layout_width= "Match_parent"Android:layout_height= "0DP"Android:layout_weight= "1">            <LinearLayoutAndroid:id= "@+id/buildingmeter_layout_unitname"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical"Android:background= "@color/white">            </LinearLayout>            <LinearLayoutAndroid:id= "@+id/buildingmeter_layout_installstatus"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical"Android:background= "@color/white">            </LinearLayout>            <LinearLayoutAndroid:id= "@+id/buildingmeter_layout_storey"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical"Android:background= "@color/white">            </LinearLayout>                    </Framelayout>    </LinearLayout></Tabhost>

Step Two: Create a layout that shows this Tabwidget tab item Tabmini.xml:

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "40dip"Android:paddingleft= "5dip"Android:paddingright= "5dip">    <TextViewAndroid:id= "@+id/tab_lable"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:gravity= "Center"Android:text= "TextView" /></LinearLayout>

Step three: Implement Tabhost in activity:

Private tabhost tabhost; Private Tabwidget Tabwidget;

Layoutinflater Inflater =Activity.getlayoutinflater (); View View1= Inflater.inflate (R.layout.tabhost_tag,NULL); TextView txt1=(TextView) View1.findviewbyid (r.id.tab_lable); Txt1.settext ("By unit name"); View View2= Inflater.inflate (R.layout.tabhost_tag,NULL); TextView txt2=(TextView) View2.findviewbyid (r.id.tab_lable); Txt2.settext ("By State"); View VIEW3= Inflater.inflate (R.layout.tabhost_tag,NULL); TextView Txt3=(TextView) View3.findviewbyid (r.id.tab_lable); Txt3.settext ("By Floor"); //get Tabhost Object instanceTabhost =(tabhost) Activity.findviewbyid (r.id.taskdescribe_buildingmeter_tabhost);//call Tabhost.setup ()Tabhost.setup (); Tabwidget=tabhost.gettabwidget ();//Create tab LabelsTabhost.addtab (Tabhost.newtabspec ("one"). Setindicator (View1). SetContent (R.id.buildingmeter_layout_unitname)); Tabhost.addtab (Tabhost.newtabspec ( "Both"). Setindicator (View2). SetContent (R.id.buildingmeter_layout_installstatus)); Tabhost.addtab ( Tabhost.newtabspec ("Three"). Setindicator (VIEW3). SetContent (R.id.buildingmeter_layout_storey)); //set the label that appears by default when you first open itTabhost.setcurrenttab (0);//Initialize the color of the tab, and the color of the fontUpdatetab (tabhost);//Select ListenerTabhost.setontabchangedlistener (NewTabchangedlistener ());

/*** Update tab label color, and font color *@paramTabhost*/    Private voidUpdatetab (Finaltabhost Tabhost) {         for(inti = 0; I < Tabhost.gettabwidget (). Getchildcount (); i++) {View View=tabhost.gettabwidget (). Getchildat (i); TextView TV=(TextView) Tabhost.gettabwidget (). Getchildat (i). Findviewbyid (r.id.tab_lable); Tv.settextsize (16); Tv.settypeface (Typeface.serif,0);//setting fonts and Styles            if(Tabhost.getcurrenttab () = =i) {//selectedView.setbackground (Getresources (). getdrawable (r.drawable.tabhost_current));//the background after selectionTv.settextcolor ( This. Getresources (). Getcolorstatelist (Android.            R.color.white)); }             Else             {                //do not selectView.setbackground (Getresources (). getdrawable (R.drawable.tabhost_default));//non-selectable backgroundTv.settextcolor ( This. Getresources (). Getcolorstatelist (Android.            R.color.black)); }        }    }        /*** Tabhost Select Listener *@author      *     */    Private classTabchangedlistenerImplementsOntabchangelistener {@Override Public voidontabchanged (String tabId) {Tabhost.setcurrenttabbytag (tabId);          Updatetab (Tabhost); }    }
