Android Animation (2) Frame animation

drawable Animations

Frame-by-frame animations is a frame-by-frame format that displays animation effects. Similar to the technique of film film shooting.

* Frame Animation:
* 1. Create the Drawable folder under the Res folder to create an XML file
* animation-list Label
* 2. Introduce this XML file in Layout controls
* 3. Get Animationdrawable Object
* 4. Call the Start method and the Stop method in Animationdrawable

The first step

Create Animation.xml under/res, drawable/,

Use <animation-list/> tags,

<?XML version= "1.0" encoding= "Utf-8"?><animation-listxmlns:android= "Http://schemas.android.com/apk/res/android" >    <item android:drawable= "@drawable/wifi1"//Picture playedandroid:duration= "+">//Play Time    </Item>    <Itemandroid:drawable= "@drawable/wifi2"android:duration= "+">    </Item>    <Itemandroid:drawable= "@drawable/wifi3"android:duration= "+">    </Item>    <Itemandroid:drawable= "@drawable/wifi4"android:duration= "+">    </Item>    <Itemandroid:drawable= "@drawable/wifi5"android:duration= "+">    </Item>    <Itemandroid:drawable= "@drawable/wifi6"android:duration= "+">    </Item></animation-list>

The second step in the layout file development component introduces the XML

    <ImageViewAndroid:id= "@+id/imageview1"Android:layout_width= "200DP"Android:layout_height= "200DP"Android:layout_alignparenttop= "true"Android:layout_centerhorizontal= "true"Android:layout_margintop= "90DP" android:src= "@drawable/animation" /> 

* 3. Get Animationdrawable Object
* 4. Call the Start method and the Stop method in Animationdrawable

 Public classMainactivityextendsActivity {ImageView IV;   Animation Animation;    animationdrawable drawable; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);         Setcontentview (R.layout.activity_main); IV=(ImageView) Findviewbyid (R.ID.IMAGEVIEW1); Drawable= (animationdrawable) iv.getdrawable (); }     Public voidClick (View v) {Switch(V.getid ()) { Caser.id.button1: drawable.start ();  Break;  Caser.id.button2: drawable.stop (); default:             Break; }    } }
