Android Animation's scaleanimation application detailed

This section explains the implementation of Scaleanimation animation in the application, the need for friends can refer to the following

4 animations are available in Android:
Alphaanimation Transparency Animation effect
Scaleanimation Zoom Animation effect
Translateanimation Displacement Animation effect
Rotateanimation Rotate animation effect

This section explains Scaleanimation animations,
Scaleanimation (float FromX, float toX, float fromY, float toy,int pivotxtype, float pivotxvalue, int pivotytype, float PIV Otyvalue)
Parameter description:

Copy CodeThe code is as follows:
Float FromX scaling on x-coordinate when animation starts
Float ToX stretch Size on x-coordinate at end of animation
Float FromY stretch size on y-coordinate when animation starts
Float ToY stretch size on y-coordinate at end of animation
int Pivotxtype animation on x-axis relative to object position type
Float Pivotxvalue The start position of the animation relative to the X coordinate of the object
int Pivotytype animation in y-axis relative to object position type
Float Pivotyvalue The start position of the animation relative to the y-coordinate of the object

Code:

Copy CodeThe code is as follows:
public class Mainactivity extends Activity {
ImageView image;
Button start;
Button Cancel;
@Override
public void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
Setcontentview (R.layout.activity_main);
Image = (ImageView) Findviewbyid (r.id.main_img);
Start = (Button) Findviewbyid (R.id.main_start);
Cancel = (Button) Findviewbyid (r.id.main_cancel);
/** Setting the Zoom animation */
Final scaleanimation animation =new scaleanimation (0.0f, 1.4f, 0.0f, 1.4f,
Animation.relative_to_self, 0.5f, Animation.relative_to_self, 0.5f);
Animation.setduration (2000);//Set animation duration
/** Common Methods */
Animation.setrepeatcount (int repeatcount);//Set the number of repetitions
Animation.setfillafter (Boolean);//Whether the animation stays in the finished state after execution
Animation.setstartoffset (long Startoffset);//wait time before execution
Start.setonclicklistener (New Onclicklistener () {
public void OnClick (View arg0) {
Image.setanimation (animation);
/** Start Animation */
Animation.startnow ();
}
});
Cancel.setonclicklistener (New Onclicklistener () {
public void OnClick (View v) {
/** End Animation */
Animation.cancel ();
}
});
}
}
