Use of Android Fragmentactivity+viewpager

Use the scene to design a "bottom menu bar + The rest of the sliding page" of the simple features.

 PackageCom.lanyuweng.mibaby;Importandroid.content.Intent;ImportAndroid.os.Bundle;Importandroid.support.v4.app.FragmentActivity;ImportAndroid.support.v4.view.ViewPager;ImportAndroid.util.Log;ImportAndroid.view.View;ImportAndroid.view.View.OnClickListener;ImportAndroid.view.Window;ImportAndroid.widget.CalendarView;ImportAndroid.widget.TextView;ImportCom.lanyuweng.mibaby.fragment.FragmentAdapter; Public classMainactivityextendsFragmentactivityImplementsonclicklistener{Private Static FinalString TAG = "mainactivity-----";  Public Static Final intTab_calendar = 0;  Public Static Final intTab_reminder = 1;  Public Static Final intTab_note = 2;  Public Static Final intTab_more = 3; PrivateCalendarView CalendarView; PrivateViewpager Viewpager; PrivateTextView Tvcalendar,tvreminder,tvnote,tvmore; //Defining Adapters    PrivateFragmentadapter Adapter; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);  This. Requestwindowfeature (Window.feature_no_title);        Setcontentview (R.layout.activity_main);    Initview (); }    Private voidInitview () {log.i (TAG,"Initview----"); Viewpager=(Viewpager) Findviewbyid (R.id.viewpager); Tvcalendar=(TextView) Findviewbyid (R.id.tvcalendar); Tvreminder=(TextView) Findviewbyid (R.id.tvreminder); Tvnote=(TextView) Findviewbyid (r.id.tvnote); Tvmore=(TextView) Findviewbyid (R.id.tvmore); Tvcalendar.setonclicklistener ( This); Tvreminder.setonclicklistener ( This); Tvnote.setonclicklistener ( This); Tvmore.setonclicklistener ( This); Adapter=NewFragmentadapter (Getsupportfragmentmanager ());    Viewpager.setadapter (adapter); } @Override Public voidOnClick (View arg0) {Switch(Arg0.getid ()) { CaseR.id.tvcalendar:viewpager.setcurrentitem (Tab_calendar);            Findviewbyid (R.id.tvconfig);  Break;  CaseR.id.tvmore:viewpager.setcurrentitem (Tab_more);  Break;  CaseR.id.tvnote:viewpager.setcurrentitem (tab_note);  Break;  CaseR.id.tvreminder:viewpager.setcurrentitem (Tab_reminder);  Break; default:             Break; }} @Overrideprotected voidOnDestroy () {//TODO auto-generated Method Stub        Super. OnDestroy (); }    }

Two ways to switch pages, swipe left and right, and tap the bottom menu bar. The second approach is to use the OnClick () method, and the second is to inherit the Fragmentpageradapter to control the display of the fragment.

 Packagecom.lanyuweng.mibaby.fragment;Importcom.lanyuweng.mibaby.MainActivity;Importandroid.support.v4.app.Fragment;ImportAndroid.support.v4.app.FragmentManager;ImportAndroid.support.v4.app.FragmentPagerAdapter; Public classFragmentadapterextendsFragmentpageradapter { Public Final Static intTab_count = 4;  PublicFragmentadapter (fragmentmanager FM) {Super(FM); } @Override PublicFragment GetItem (intarg0) {        Switch(arg0) { CaseMainActivity.TAB_CALENDAR:CalendarFragment calendarfragment=Newcalendarfragment (); returncalendarfragment;  CaseMainActivity.TAB_REMINDER:ReminderFragment reminderfragment=Newreminderfragment (); returnreminderfragment;  CaseMainActivity.TAB_NOTE:NoteFragment notefragment=Newnotefragment (); returnnotefragment;  CaseMainActivity.TAB_MORE:MoreFragment morefragment=Newmorefragment (); returnmorefragment; }        return NULL; } @Override Public intGetCount () {//TODO auto-generated Method Stub        returnTab_count; }} 

At the same time, XML is:

<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"Xmlns:tools= "Http://schemas.android.com/tools"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"Android:background= "@drawable/background"android:orientation= "Vertical" > <Android.support.v4.view.ViewPager Android:id= "@+id/viewpager"Android:layout_width= "Fill_parent"Android:layout_height= "Match_parent"Android:layout_weight= "9"/> <LinearLayout android:layout_width= "Fill_parent"Android:layout_height= "55SP"Android:layout_weight= "1"Android:background= "@color/burlywood"android:orientation= "Horizontal" > <TextView Android:id= "@+id/tvcalendar"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_gravity= "Center_vertical"Android:layout_weight= "1"Android:drawabletop= "@drawable/calendar"android:gravity= "Center"Android:text= "@string/calendar"android:textsize= "12SP"Tools:ignore= "Nestedweights" > </TextView> <TextView Android:id= "@+id/tvreminder"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_gravity= "Center_vertical"Android:layout_weight= "1"Android:drawabletop= "@drawable/reminder"android:gravity= "Center"Android:text= "@string/reminder"android:textsize= "12SP" > </TextView> <TextView Android:id= "@+id/tvnote"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_gravity= "Center_vertical"Android:layout_weight= "1"Android:drawabletop= "@drawable/note"android:gravity= "Center"Android:text= "@string/note"android:textsize= "12SP" > </TextView> <TextView Android:id= "@+id/tvmore"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_gravity= "Center_vertical"Android:layout_weight= "1"Android:drawabletop= "@drawable/more"android:gravity= "Center"Android:text= "@string/more"android:textsize= "12SP" > </TextView> </LinearLayout></LinearLayout>
