Android Animation 2

I wrote Android animation 1 a long time ago, but it was just fun to play, and a lot of knowledge was not complete.

Now summarize.

Basic Android animations are: pan, rotate, zoom, and transparency.

Here's an example:

First Look at panning:

Fromxtype  The type of horizontal play Fromxvalue start with, 0 represents the current position toxtype,   to what location type Toxvalue to what coordinates fromytype the type of vertical play fromyvalue from where to start, 0 indicates the current position toytype to what position the type Toyvalue to what coordinates translateanimation translate = new Translateanimation (            animation.relative_ To_self,-2,             animation.relative_to_self, 2,             animation.relative_to_self, 0,            animation.relative_to_self , 1);    Set display time    translate.setduration (+);    Play resource for Infinite loop    translate.setrepeatcount (animation.infinite);    Playback mode, anti-retransmission put, the first along the end of the broadcast, on the opposite play    Translate.setrepeatmode (animation.reverse);    Which component is playing, set    imageview.setanimation (translate);    Start playing    Translate.start ();

Rotating:

/     * * fromdegrees, starting from what angle 0 from now todegrees, 270 degrees Pivotxtype, x center point type     * animation.relative_to_self itself pivotxvalue, medium The heart point value of 0.5 indicates that the image is half-     pivotytype, y-center-point type animation.relative_to_self itself     *  pivotyvalue 0.5f    */ Rotateanimation rotate = new Rotateanimation (0, Animation.relative_to_self,            0.5f, animation.relative_to_self ,            3);    Playback display time    rotate.setduration (;    Rotate.setrepeatcount (animation.infinite);    Rotate.setrepeatmode (Animation.restart);    Imageview.setanimation (rotate);    Rotate.start ();

Scaling:

/     * * FromX, ToX, from the coordinates of what address start to what coordinates, 0, represents the current FromY, ToY,      * pivotxtype,  the center of rotation     * pivotxvalue, type, Pivotytype, Pivotyvalue     *    /scaleanimation scale = new Scaleanimation (1, 2, 1,-2            , Animation.relative_to_self,-2, Animation.relative_to_self, 3);    Playback display time    scale.setduration (;    Scale.setrepeatcount (animation.infinite);    Scale.setrepeatmode (Animation.restart);    Imageview.setanimation (scale);    Scale.start ();

Final transparency:

       /* * Fromalpha,  from what transparency starts     * Toalpha to what transparency ends *    /alphaanimation alpha = new Alphaanimation (1, 0 );    Playback display time    alpha.setduration (+);    Alpha.setrepeatcount (animation.infinite);    Alpha.setrepeatmode (animation.reverse);            Imageview.setanimation (Alpha);            Alpha.start ();}
