How to Use tabhost in Fragment

Recently, I was working on a quasi-e-commerce app. because I used the fragment technology, I want to make the tabhost interface effect in a fragment. After searching for information, I found a solution. I 'd like to share it with you! (Do not spray for new users !)

The first control to be used is the control in support V4, XML

<android.support.v4.app.FragmentTabHost        xmlns:android="http://schemas.android.com/apk/res/android"        android:id="@android:id/tabhost"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_below="@+id/action_fun" >        <LinearLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical" >            <TabWidget                android:id="@android:id/tabs"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:layout_weight="0"                android:orientation="horizontal" >            </TabWidget>            <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal"             android:layout_weight="1" >            <ImageView            android:id="@+id/img_scrollbar_fun"            android:layout_width="match_parent"            android:layout_height="4dp"            android:layout_weight="2"            android:scaleType="fitXY"            android:src="@drawable/scrollbar" />            <View            android:id="@+id/textView1"            android:layout_width="wrap_content"            android:layout_height="0dp"            android:layout_weight="1" />            </LinearLayout>            <FrameLayout                android:id="@android:id/tabcontent"                android:layout_width="0dp"                android:layout_height="0dp"                android:layout_weight="0" />            <FrameLayout                android:id="@+id/realtabcontent"                android:layout_width="match_parent"                android:layout_height="0dp"                android:layout_weight="1" />        </LinearLayout>    </android.support.v4.app.FragmentTabHost>

This XML is the control found from support V4, And the custom dynamic scroll bar is displayed.

The code implementation is as follows:

Public class funfragment extends fragment implements extends {public funfragment () {// required empty public constructor} private fragmenttabhost mtabhost_fun; private string [] fun_tabs = new string [] {" ", "tag", "Follow"}; private imageview succeeded; private float lastoffset_fun; @ overridepublic view oncreateview (layoutinflater Inflater, viewgroup container, bundle savedinstancestate) {view layout = Inflater. inflate (R. layout. fragment_fun, container, false); mimgscrollbar_fun = (imageview) layout. findviewbyid (R. id. response); initactionbar (); // inittabfragment (); inittabhost (layout); return layout;} private void initactionbar () {fragmentmanager fm = getchildfragmentmanager (); fragmenttransaction Ft = FM. begintransaction (); actionfragment = new actionfragment (); ft. add (R. id. action_fun, actionfragment); actionfragment. setactionname ("fun"); ft. commit ();} // initialize fragmenttabhostpublic void inittabhost (view layout) {mtabhost_fun = (fragmenttabhost) layout. findviewbyid (Android. r. id. tabhost); mtabhost_fun.setup (getactivity (), getchildfragmentmanager (), R. id. realtabcontent); mtabhost_fun.setontabchangedlistener (this); For (INT I = 0; I <fun_tabs.length; I ++) {view = getactivity (). getlayoutinflater (). inflate (R. layout. fun_tabhost_item, null); textview mtextview = (textview) view. findviewbyid (R. id. TV _fun_tab); mtextview. settext (fun_tabs [I]); mtabhost_fun.addtab (mtabhost_fun.newtabspec ("tag" + I ). setindicator (view), recfragment. class, null) ;}@ overridepublic void ontabchanged (string Tabid) {int position = mtabhost_fun.getcurrenttab (); // you can specify setscrollanimation (position) for the scrolling animation bar );} // set Private void setscrollanimation (INT position) {// obtain the screen width windowmanager mwindowmanager = (windowmanager) getactivity (). getsystemservice (context. window_service); display = mwindowmanager. getdefadisplay display (); @ suppresswarnings ("deprecation") int width = display. getwidth (); // get the offset int offset of the scroll bar = width/fun_tabs.length; // use the open-source project nineold to set the rolling animation objectanimator offloat = objectanimator. offloat (mimgscrollbar_fun, "translationx", lastoffset_fun, position * offset); offloat. setinterpolator (New decelerateinterpolator (); offloat. setduration (500 ). start (); // The Position of the previous offset lastoffset_fun = position * offset ;}}

Recording This is also a souvenir for learning android. I hope it will be helpful to my friends who have just learned android.
