Android development for ListView set layout animation effect

1. By adding Java code , the resource file is basically not modified

XML file, just add a ListView and do not paste the code of the XML file.

Java code:

1  Public classMainactivityextendsActivity {2 3 @Override4     protected voidonCreate (Bundle savedinstancestate) {5         Super. OnCreate (savedinstancestate);6 Setcontentview (r.layout.activity_main);7 8Scaleanimation sa=NewScaleanimation (0, 1, 0, 1);9Sa.setduration (1000);TenLayoutanimationcontroller lac=NewLayoutanimationcontroller (SA, 0.5f); One Lac.setorder (layoutanimationcontroller.order_reverse); A  -ListView lv=(ListView) Findviewbyid (r.id.lv); -Arrayadapter<string> adapter=NewArrayadapter<string> (Getapplicationcontext (), Android. R.layout.simple_list_item_1,Newstring[]{"Beijing", "Xian", "Shanghai", "Nanjing"}); the Lv.setadapter (adapter); - Lv.setlayoutanimation (LAC); -         } -}

2. Add animation effects through a resource file

To create a new Android XML fils, on the new page, Resource type selected for tween animation,root element is selected as Alpha. (You can also set multiple animation effects together)

Scale_anim.xml

1 <?XML version= "1.0" encoding= "Utf-8"?>2 < Scalexmlns:android= "Http://schemas.android.com/apk/res/android"3 Android:fromxscale= "0"4 Android:toxscale= "1"5 Android:fromyscale= "0"6 Android:toyscale= "1"7 android:duration= "+">8 </ Scale>

Create a new Android XML fils

Listview_anim.xml

 1  <?  xml version= "1.0" encoding= "Utf-8"  ?>  2   xmlns:android   3   Android:animation  = "@anim/scale_anim"  4   Android:delay  = "0.5"  5  </ layoutanimation  >  

In the Main-activity.xml file, set the properties of the ListView

1     <  android:id= "@+id/lv"2        android:layout_width= "Match_parent "3        android:layout_height=" Match_parent "4         Android:layoutanimation= "@anim/listview_anim"></listview>
