tweened Animation Tween

1. Transparency Gradient Animation (alphaanimation)

1) Pure Code implementation

Animation Animation = new Alphaanimation (1f,0.1f);

Parameter 1: Starting transparency;

Parameter 2: target transparency;

//implementing the Gradient featureAnimationset Aset =NewAnimationset (true); Alphaanimation Alpha=NewAlphaanimation (1,0);//fully displayed -//fully TransparentAlpha.setduration ( the);//3 seconds to complete the animationAset.addanimation (Alpha);//Add animationsMainactivity. This. Img.startanimation (Aset);//Start Animation

2) XML file implementation (new XML under new Anim file under Res file)

Xml:

<SetXmlns:android="http://schemas.android.com/apk/res/android"><Alpha Android:repeatmode="Restart"Android:repeatcount="3"android:duration=" -"Android:fromalpha="1"Android:toalpha="0"> </alpha></Set>

Java:

Animation anim = animationutils.loadanimation (mainactivity.  this,                    r.anim.alpha);            Mainactivity.  This // Start Animation

2. Rotate

Animation Animation = new Rotateanimation (360,0,animation.relative_to_self,0.5f,animation.relative_to_self,0.5f);

Parameter 1: Starting angle of rotation

Parameter 2: End angle of rotation

Parameter 3: X-axis value reference method for the center of rotation

Parameter 4: The value of the center point x-axis

Parameter 5: The y-axis value reference method of the center of rotation

Parameter 6: Value of the y-axis of the center point

1) Pure Code implementation

Animationset RSet =NewAnimationset (true); Rotateanimation Rotate=NewRotateanimation (0,360,//0~360度animation.relative_to_parent,0.5f,//x-axis start positionanimation.relative_to_parent,0.0f);//y-axis move positionRotate.setduration (3000);//3 seconds to complete the animationRset.addanimation (rotate);//Add animationsmainactivity. This. Image.startanimation (RSet);//Start Animation

2) XML implementation

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android" >    <rotate        android:fromdegrees= "0.0"        android:todegrees= "+360.0"         Android:pivotx= "50%p"        android:pivoty= "0%p"        android:duration= "/></" Set>

3. Zooming

Animation Animation = new

Scaleanimation (1f,0.2f,1f,0.2f,animation.relative_to_self,0.5f,animation.relative_to_self,0.5f);

Parameter 1:x direction start size (1f indicates original size)

Parameter 2:x direction stop size (0.2f = 0.2 times times the original)

Parameter 3:y direction start size (1f indicates original size)

Parameter 4:y direction stop size (0.2f = 0.2 times times the original)

Parameter 5: Scaling center point x-axis value reference method

Parameter 6: The value of the center point x-axis (0.5f = 0.5 times times the original)

Parameter 7: Zoom center point y-axis value reference method

Parameter 8: The value of the y-axis of the center point (0.5f means 0.5 times times the original)

1) Code implementation

//Implementing the Zoom functionAnimationset Sset =NewAnimationset (true); Scaleanimation Scale=NewScaleanimation (1, 0.0f, 1, 0.0f, Animation.relative_to_self,0.5f, Animation.relative_to_self,0.5f); Scale.setduration (3000);//3 seconds to complete the animationSset.addanimation (scale);//Add animationsMainactivity. This. Image.startanimation (Sset);//Start Animation

2) XML implementation

<set xmlns:android= "Http://schemas.android.com/apk/res/android" >    <scale        Android:fromxscale = "1.0"        android:toxscale= "0.0"        android:fromyscale= "1.0"        Android:toyscale = "0.0"        android:pivotx= "50%"        android:pivoty= "50%"        android: Startoffset= "        android:repeatcount" = "3"        android:duration= "+"/> </set>

4. Panning Animations

Animation Animation = new Translateanimation (0,50,0,50);

The starting position of the 1:X axis of the parameter

Parameter 2:x the end position of the axis

The starting position of the 3:y axis of the parameter

Parameter 4:y the end position of the axis

1) Code implementation

//Implement MobileAnimationset Tset =NewAnimationset (true); Translateanimation Tran=Newtranslateanimation (animation.relative_to_self,0.0f,//x-axis start positionanimation.relative_to_self,0.5f,//end position of x-axis movementanimation.relative_to_self,0.0f,//y-axis start positionanimation.relative_to_self,0.5f);//y-axis move positionTran.setduration (3000);//3 seconds to complete the animationTset.addanimation (Tran);//Add animationsMainactivity. This. Image.startanimation (Tset);//Start Animation

2) XML implementation

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android" >    <translate        android:fromxdelta= "0.0"        android:toxdelta= "50%"         Android:fromydelta= "0.0"        android:toydelta= "150%"        android:duration= "/>" </set>

5. Mixed animations

1) Code implementation

Animationset Tset =NewAnimationset (true); Aset=NewAnimationset (true); Alphaanimation Alph=NewAlphaanimation (0, 1); Alph.setrepeatcount (3); Alph.setduration (5000);                                 Aset.addanimation (Alph); Translateanimation Tran=Newtranslateanimation (animation.relative_to_self,0.0f,//x-axis start positionanimation.relative_to_self,0.5f,//end position of x-axis movementanimation.relative_to_self,0.0f,//y-axis start positionanimation.relative_to_self,0.5f);//y-axis move positionTran.setduration (3000);//3 seconds to complete the animationtset.addanimation (Alph);//Add animationsTset.addanimation (Tran);//Add animationsmainactivity. This. Image.startanimation (Tset);//Start Animation

2) XML Configuration implementation

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android" > <Translate Android:fromxdelta= "0.0"Android:toxdelta= "50%"Android:fromydelta= "0.0"Android:toydelta= "150%"android:duration= "/>" <Scale Android:fromxscale= "1.0"Android:toxscale= "0.0"Android:fromyscale= "1.0"Android:toyscale= "0.0"Android:pivotx= "50%"Android:pivoty= "50%"Android:startoffset= "100"Android:repeatcount= "3"android:duration= "/></set>"
