Extract the animation effect of the next path menu. Look at the map first.

Principle:
Click the red plus sign to trigger the event:
public static void Startanimationsin (ViewGroup viewgroup,int durationmillis) {
for (int i = 0; i < Viewgroup.getchildcount (); i++) {
ImageButton Inoutimagebutton = (ImageButton) viewgroup
. Getchildat (i);
Inoutimagebutton.setvisibility (0);
Marginlayoutparams MLP = (marginlayoutparams) inoutimagebutton.getlayoutparams ();
Animation Animation = new Translateanimation (Mlp.rightmargin-xoffset,0f,yoffset + mlp.bottommargin, 0F);
This place is the difference between the relative and absolute position, in fact, there are 4 parameters are not shown, but she will automatically identify according to the unit. The original sentence should be:
New Translateanimation (Animation.absolute,mlp.rightmargin-xoffset, animation.relative_to_self,0f, Animation.absolute, Yoffset + mlp.bottommargin, animation.relative_to_self,0f);

Animation.setfillafter (True); Animation.setduration (Durationmillis);
Animation.setstartoffset ((i * 100)
/( -1 + viewgroup.getchildcount ());
Animation.setinterpolator (New Overshootinterpolator (2F));
Inoutimagebutton.startanimation (animation);

}
The copy code occurs with a move animation. Hidden is
Animation Animation = new Translateanimation (0f,mlp.rightmargin-xoffset, 0f,yoffset + mlp.bottommargin);

Where Xoffset Yoffset is the distance from the screen margin from the end item in the layout.
private static int xoffset = 15;
private static int yoffset =-13;
public static void Initoffset {//by layout file
Xoffset = (int) (10.667 *context.getresources (). Getdisplaymetrics (). density);
Yoffset =-(int) (8.667 *context.getresources (). Getdisplaymetrics (). density);
}
The following figure

It is worth mentioning the use of interpolator, the path of the use of Overshootinterpolator and Anticipateinterpolator.
Interpolator is used to modify the animation effect, define the rate of change of animation, can make the existing animation effect can be accelerated (acceleration), decelerated (deceleration), repeated (repeat), bounced (bounce) and so on.
Acceleratedecelerateinterpolator at the beginning of the animation with the introduction of the local rate change slower, in the middle of the time to accelerate
Accelerateinterpolator at the beginning of the animation, the rate changes slowly, and then starts to accelerate
Anticipateinterpolator starts back and forwards.
Anticipateovershootinterpolator the last value when you start backwards and then forward a certain value
Bounceinterpolator animation at the end of the play
Cycleinterpolator animation loops play a specific number of times, the rate changes along the sine curve
Decelerateinterpolator at the beginning of the animation fast and slow
Linearinterpolator change at constant rate
Overshootinterpolator forward a certain value and then back to the original position

Thanks to the hard work of the Little Bear fart, add the button item click to enlarge the animation

Another modification: Add a statement that removes the six button focus after the animation is finished, preventing the event from being blocked to the level below.

Trigger long by event after floating principle:
Windowparams = new Windowmanager.layoutparams ();
windowparams.gravity = Gravity.top | Gravity.left;
Windowparams.x = X-ITEMWIDTH/2;
Windowparams.y = Y-ITEMHEIGHT/2;
Windowparams.height = WindowManager.LayoutParams.WRAP_CONTENT;
Windowparams.width = WindowManager.LayoutParams.WRAP_CONTENT;

ImageView IV = new ImageView (GetContext ());
Iv.setimagebitmap (BM);
WindowManager = (WindowManager) getcontext (). Getsystemservice (
Context.window_service);//"Window"
Windowmanager.addview (iv, Windowparams);
Drag effect:
if (Dragimageview!= null) {
Windowparams.alpha = 0.6f;
Windowparams.x = X-ITEMWIDTH/2;
Windowparams.y = Y-ITEMHEIGHT/2;
Windowmanager.updateviewlayout (Dragimageview, windowparams);
}
