Andorid Popupwindow updates the implementation of the animation, you can achieve a window is pushed up by a window effect

Recently due to the project needs, has been looking for a pop-up window, in another pop-up window pop-up, pushed up the effect, incredibly find, after unremitting efforts, finally realized the Popupwindow in the update when the animation.

First on the code:

1 ImportAndroid.animation.ObjectAnimator;2 ImportAndroid.annotation.SuppressLint;3 ImportAndroid.content.Context;4 Importandroid.graphics.drawable.BitmapDrawable;5 ImportAndroid.util.AttributeSet;6 ImportAndroid.view.LayoutInflater;7 ImportAndroid.view.View;8 ImportAndroid.widget.PopupWindow;9 ImportAndroid.widget.TextView;Ten  One  Public classNotepopwindowextendsPopupwindow { A     PrivateTextView Mnodetextview; -     PrivateContext Mcontext; -     PrivateViewwrapper Mwrapper; the  -      PublicNotepopwindow (Context context,intWidthintheight) { -         Super(Layoutinflater.from (context). Inflate (R.layout.fullscreen_view_note_popwindow,NULL), width, height); -Mcontext =context; +Setbackgrounddrawable (Newbitmapdrawable ()); - Setanimationstyle (r.style.anim_note_bottombar); + initviews (); A     } at  -      PublicNotepopwindow (Context context) { -         Super(context); -  -     } -  in      PublicNotepopwindow (Context context, AttributeSet AttributeSet) { -         Super(context, attributeset); to     } +  -     Private voidinitviews () { theMnodetextview =(TextView) Getcontentview (). Findviewbyid (R.id.note_view); *Mwrapper =NewViewwrapper (Getcontentview ()); $     }Panax Notoginseng  -@SuppressLint ("Newapi") the      Public voidstartupanimation () { +Objectanimator translationright = Objectanimator.ofint (Mwrapper, "Y", (int) mcontext.getresources () A . Getdimension (R.dimen.bottom_menu_window_height)); theTranslationright.setduration (540); + Translationright.start (); -     } $  $@SuppressLint ("Newapi") -      Public voidstartdownanimation () { -Objectanimator translationright = Objectanimator.ofint (Mwrapper, "Y", 0); theTranslationright.setduration (360); - Translationright.start ();Wuyi     } the  -     Private classViewwrapper { Wu         PrivateView Mtarget; -         Private BooleanIsUp =true; About  $          PublicViewwrapper (View target) { - Setmtarget (target); -         } -  A@SuppressWarnings ("Unused") +          Public intGetY () { the             if(isUp) { -IsUp =false; $                 return0; the  the}Else { theIsUp =true; the                 return(int) mcontext.getresources (). Getdimension (r.dimen.bottom_menu_window_height); -             } in  the         } the  About@SuppressWarnings ("Unused") the          Public voidSety (intheight) { theUpdate (0, height,-1, 1); the         } +  -@SuppressWarnings ("Unused") the          PublicView Getmtarget () {Bayi             returnMtarget; the         } the  -          Public voidSetmtarget (View mtarget) { -              This. Mtarget =Mtarget; the         } the     } the}

The implementation of the principle is to rely on property animation, but the property animation can only be used for the set and get method properties, so the key is to write a wrapper class, provide the property's set and get method, in the Set method call Popwindow Update method, can be implemented in the update animation.

Speak is not very clear, code such as above, if really do not understand can mail, QQ contact ...
