Two days ago in order to see Comics, downloaded an animation app, open a look, sliding unexpectedly below the tab with the above Titel are hidden, into full-screen, feel good to look like oh, I thought it was hidden with the reality of the property that, then a careful look, not, then only the animation to achieve, It also seems to be done with attribute animations: Property Animations Change the properties of an object. Do not know this effect is not good, should be suitable for some full-screen reading class app.

Let's see how it works:


Look at the effect we have:


Well, the code is very rare to achieve this effect:

Package Com.example.hidetitle;import Android.annotation.suppresslint;import Android.app.activity;import Android.os.bundle;import Android.view.motionevent;import Android.view.view;import Android.view.viewpropertyanimator;import Android.view.view.ontouchlistener;import Android.widget.ArrayAdapter; Import Android.widget.linearlayout;import Android.widget.listview;public class Mainactivity extends Activity {private Boolean ismove = True;private viewpropertyanimator animatebottom,animatetop; @SuppressLint ("Newapi") @ overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_main); ListView Mlistview = (ListView) Findviewbyid (R.id.my_listview); LinearLayout Tabbottom = (linearlayout) Findviewbyid (R.id.tabbottom); LinearLayout tabtop = (linearlayout) Findviewbyid (r.id.tabtop); animatebottom = Tabbottom.animate (); animatetop = Tabtop . Animate (); arrayadapter<string> adapter = new Arrayadapter<string> (this,android. R.layOut.simple_expandable_list_item_1); for (int i = 0; i <; i++) {Adapter.add (i + "");} Mlistview.setadapter (adapter); Mlistview.setontouchlistener (new Ontouchlistener () {Private float Y;private Boolean down = true;private float lasty; @Overridepublic boolean OnTouch (View V, motionevent event) {switch (event.getaction ()) {CA Se motionevent.action_down:y = event.gety (); if (down) {lasty = y;} Down = false;break;case Motionevent.action_move:break;case MotionEvent.ACTION_UP:down = true;if (Lasty-event.gety () & Lt -5) {onscrollreset ();} else if (Lasty-event.gety () > 5) {onscroll ();} break;} return false;}}); @SuppressLint ("Newapi") public void onscroll () {if (ismove) {animatebottom.setduration (200); Animatetop.setduration ($). Translationy ( -200); ismove = false;}} @SuppressLint ("Newapi") public void Onscrollreset () {if (!ismove) {animatebottom.setduration (0); Animatetop.setduration ($). Translationy (0); ismove = True;}}}
Xml:

<framelayout xmlns:android= "http://schemas.android.com/apk/res/android" android:layout_width= "Fill_parent" android:layout_height= "Fill_parent" > <listview android:id= "@+id/my_listview" android:layout_width= "Match_parent" android:layout_height= "match_parent" > </ListView> <relativelayout android: Layout_width= "Match_parent" android:layout_height= "match_parent" > <linearlayout android:id = "@+id/tabbottom" android:layout_width= "match_parent" android:layout_height= "50dip" Andro            Id:layout_alignparentbottom= "true" android:background= "#880090D9" android:gravity= "center" android:orientation= "vertical" > <textview android:id= "@+id/textview1" an                Droid:layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:text= "title" Android:textcolor="#ffffff" android:textsize= "18sp"/> </LinearLayout> <linearlayout            Android:id= "@+id/tabtop" android:layout_width= "match_parent" android:layout_height= "50dip"            Android:layout_alignparenttop= "true" android:background= "#880090D9" android:gravity= "center"                android:orientation= "vertical" > <textview android:layout_width= "wrap_content" android:layout_height= "Wrap_content" android:text= "title" Android:textcolor= "#ff FFFF "android:textsize=" 18sp "/> </LinearLayout> </relativelayout></framelayout >


Fun!
