The realization of Java-android's animation

One: Show hidden animation

Create a Anim directory in the Res directory and create a alpha.xml file inside

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shareinterpolator= "false"    >   <alpha     android:fromalpha= "1.0"    android:toalpha= "0"    android:duration=    ></alpha> </set>

Add a picture to the displayed page, and then in the Mainactivity.java file, get the object that needs to be animated, get an animated object that will animate the object to animate the method

Package Cn.szy.com;import Android.app.activity;import Android.os.bundle;import android.view.animation.Animation; Import Android.view.animation.animationutils;import Android.widget.imageview;public class MainActivity extends Activity {    /** called when the activity is first created. *    /@Override public    void OnCreate (Bundle Savedinstan Cestate) {        super.oncreate (savedinstancestate);        Setcontentview (r.layout.main);                Animation Animation = Animationutils.loadanimation (this, r.anim.alpha);        Animation.setfillafter (true);        ImageView ImageView = (ImageView) This.findviewbyid (r.id.imageview1);        Imageview.startanimation (animation);    }}

Two: Mobile animation

Create a Anim directory in the Res directory, then create a translate.xml file inside it and then load it in the animation.

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shareinterpolator= "false"    ><translate     android:fromxdelta= "0"    Android:fromydelta = "0"    android:toxdelta= "    android:toydelta=" "    android:duration="    ></translate >    </set>

Three: Rotate animation

Create a Anim directory in the Res directory, then create a rotate.xml file inside it and then load it in the animation.

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shareinterpolator= "false"    ><rotate     android:fromdegrees= "0"        android: Todegrees= "android:pivotx="    50% "    android:pivoty=" 50% "android:duration="    >< /rotate>    </set>

Four: Enlarge animation

Create a Anim directory in the Res directory, then create a scale.xml file inside it and then load it in the animation.

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shareinterpolator= "false" ><scale     android:fromxscale= "1.0"    android:fromyscale= "1.0"    android:toxscale= "5.0"    android:toyscale= "5.0"    android:pivotx= "50%"    android:pivoty= "50%"    android:duration= "/></set>"    

V: Set animation, the action of multiple animations written into a file, in order and time to call, you can achieve some complex animation

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     android:shareinterpolator= "false"    ><translate     android:fromxdelta= "0"    Android:fromydelta = "0"    android:toxdelta= "    android:toydelta=" "    android:duration="    ></translate >    <scale     android:fromxscale= "1.0"    android:fromyscale= "1.0"    android:toxscale= "5.0"    android:toyscale= "5.0"    android:pivotx= "50%"    android:pivoty= "50%"    android:duration= "5000"    />           <alpha            android:fromalpha= "1.0"           android:toalpha= "0"           android:duration= "5000"    /></set>
