Android: an animation of the pop-up menu (2)

If you create a pop-up control, you can add the view:

Write class SatelliteMenu extends FrameLayout

private void init(Context context, AttributeSet attrs, int defStyle) {inflate(context, R.layout.sat_main, this);imgMain = (ImageView) findViewById(R.id.sat_main);if(attrs != null){            TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.SatelliteMenu, defStyle, 0);satelliteDistance = typedArray.getDimensionPixelSize(R.styleable.SatelliteMenu_satelliteDistance, DEFAULT_SATELLITE_DISTANCE);totalSpacingDegree = typedArray.getFloat(R.styleable.SatelliteMenu_totalSpacingDegree, DEFAULT_TOTAL_SPACING_DEGREES);closeItemsOnClick = typedArray.getBoolean(R.styleable.SatelliteMenu_closeOnClick, DEFAULT_CLOSE_ON_CLICK);expandDuration = typedArray.getInt(R.styleable.SatelliteMenu_expandDuration, DEFAULT_EXPAND_DURATION);//float satelliteDistance = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 170, getResources().getDisplayMetrics());typedArray.recycle();}mainRotateLeft = SatelliteAnimationCreator.createMainButtonAnimation(context);mainRotateRight = SatelliteAnimationCreator.createMainButtonInverseAnimation(context);Animation.AnimationListener plusAnimationListener = new Animation.AnimationListener() {@Overridepublic void onAnimationStart(Animation animation) {}@Overridepublic void onAnimationRepeat(Animation animation) {}@Overridepublic void onAnimationEnd(Animation animation) {plusAnimationActive.set(false);}};mainRotateLeft.setAnimationListener(plusAnimationListener);mainRotateRight.setAnimationListener(plusAnimationListener);imgMain.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {SatelliteMenu.this.onClick();}});internalItemClickListener = new InternalSatelliteOnClickListener(this);}

Then write the logic for adding an Item:

Public void addItems (List
 
  
Items) {menuItems. addAll (items); this. removeView (imgMain); TextView tmpView = new TextView (getContext (); tmpView. setLayoutParams (new FrameLayout. layoutParams (0, 0); float [] degrees = getDegrees (menuItems. size (); int index = 0; for (SatelliteMenuItem menuItem: menuItems) {int finalX = SatelliteAnimationCreator. getTranslateX (degrees [index], satelliteDistance); int finalY = SatelliteAnimationCreator. getTranslateY (degrees [index], satelliteDistance); ImageView itemView = (ImageView) LayoutInflater. from (getContext ()). inflate (R. layout. sat_item_cr, this, false); ImageView cloneView = (ImageView) LayoutInflater. from (getContext ()). inflate (R. layout. sat_item_cr, this, false); itemView. setTag (menuItem. getId (); cloneView. setVisibility (View. GONE); itemView. setVisibility (View. GONE); cloneView. setOnClickListener (internalItemClickListener); cloneView. setTag (Integer. valueOf (menuItem. getId (); FrameLayout. layoutParams layoutParams = getLayoutParams (cloneView); layoutParams. bottomMargin = Math. abs (finalY); layoutParams. leftMargin = Math. abs (finalX); cloneView. setLayoutParams (layoutParams );
  // Put cloneView at the end of the itemview animation.If (menuItem. getImgResourceId ()> 0) {itemView. setImageResource (menuItem. getImgResourceId (); cloneView. setImageResource (menuItem. getImgResourceId ();} else if (menuItem. getImgDrawable ()! = Null) {itemView. setImageDrawable (menuItem. getImgDrawable (); cloneView. setImageDrawable (menuItem. getImgDrawable ();} Animation itemOut = SatelliteAnimationCreator. createItemOutAnimation (getContext (), index, expandDuration, finalX, finalY); Animation itemIn = SatelliteAnimationCreator. createItemInAnimation (getContext (), index, expandDuration, finalX, finalY); Animation itemClick = SatelliteAnimationCreator. createItemClickAnimation (getContext (); menuItem. setView (itemView); menuItem. setCloneView (cloneView); menuItem. setInAnimation (itemIn); menuItem. setOutAnimation (itemOut); menuItem. setClickAnimation (itemClick); menuItem. setFinalX (finalX); menuItem. setFinalY (finalY); itemIn. setAnimationListener (new SatelliteAnimationListener (itemView, true, viewToItemMap); itemOut. setAnimationListener (new SatelliteAnimationListener (itemView, false, viewToItemMap); itemClick. setAnimationListener (new SatelliteItemClickAnimationListener (this, menuItem. getId (); this. addView (itemView); this. addView (cloneView); viewToItemMap. put (itemView, menuItem); viewToItemMap. put (cloneView, menuItem); index ++;} this. addView (imgMain );}
 

Listener:

private static class SatelliteAnimationListener implements Animation.AnimationListener {private WeakReference
 
   viewRef;private boolean isInAnimation;private Map
  
    viewToItemMap;public SatelliteAnimationListener(View view, boolean isIn, Map
   
     viewToItemMap) {this.viewRef = new WeakReference
    
     (view);this.isInAnimation = isIn;this.viewToItemMap = viewToItemMap;}@Overridepublic void onAnimationStart(Animation animation) {if (viewRef != null) {View view = viewRef.get();if (view != null) {SatelliteMenuItem menuItem = viewToItemMap.get(view);if (isInAnimation) {menuItem.getView().setVisibility(View.VISIBLE);menuItem.getCloneView().setVisibility(View.GONE);} else {menuItem.getCloneView().setVisibility(View.GONE);menuItem.getView().setVisibility(View.VISIBLE);}}}}@Overridepublic void onAnimationRepeat(Animation animation) {}@Overridepublic void onAnimationEnd(Animation animation) {if (viewRef != null) {View view = viewRef.get();if (view != null) {SatelliteMenuItem menuItem = viewToItemMap.get(view);if (isInAnimation) {menuItem.getView().setVisibility(View.GONE);menuItem.getCloneView().setVisibility(View.GONE);} else {menuItem.getCloneView().setVisibility(View.VISIBLE);menuItem.getView().setVisibility(View.GONE);}}}}}
    
   
  
 

OnMeature must be rewritten:

private void recalculateMeasureDiff() {int itemWidth = 0;if (menuItems.size() > 0) {itemWidth = menuItems.get(0).getView().getWidth();}measureDiff = Float.valueOf(satelliteDistance * 0.2f).intValue()+ itemWidth;}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {super.onMeasure(widthMeasureSpec, heightMeasureSpec);recalculateMeasureDiff();int totalHeight = imgMain.getHeight() + satelliteDistance + measureDiff;int totalWidth = imgMain.getWidth() + satelliteDistance + measureDiff;System.out.println("====totalWidth="+totalWidth+"height="+totalHeight+"measureDiff="+measureDiff+"imgMain.getWidth()="+imgMain.getWidth());setMeasuredDimension(totalWidth, totalHeight);}

Save and restore activity status:

@Overrideprotected Parcelable onSaveInstanceState() {Parcelable superState = super.onSaveInstanceState();SavedState ss = new SavedState(superState);ss.rotated = rotated;ss.totalSpacingDegree = totalSpacingDegree;ss.satelliteDistance = satelliteDistance;ss.measureDiff = measureDiff;ss.expandDuration = expandDuration;ss.closeItemsOnClick = closeItemsOnClick;return ss;}@Overrideprotected void onRestoreInstanceState(Parcelable state) {SavedState ss = (SavedState) state;rotated = ss.rotated;totalSpacingDegree = ss.totalSpacingDegree;satelliteDistance = ss.satelliteDistance;measureDiff = ss.measureDiff;expandDuration = ss.expandDuration;closeItemsOnClick = ss.closeItemsOnClick;super.onRestoreInstanceState(ss.getSuperState());}static class SavedState extends BaseSavedState {boolean rotated;private float totalSpacingDegree;private int satelliteDistance;private int measureDiff;private int expandDuration;private boolean closeItemsOnClick;SavedState(Parcelable superState) {super(superState);}public SavedState(Parcel in) {super(in);rotated = Boolean.valueOf(in.readString());totalSpacingDegree = in.readFloat();satelliteDistance = in.readInt();measureDiff = in.readInt();expandDuration = in.readInt();closeItemsOnClick = Boolean.valueOf(in.readString());}@Overridepublic int describeContents() {return 0;}@Overridepublic void writeToParcel(Parcel out, int flags) {out.writeString(Boolean.toString(rotated));out.writeFloat(totalSpacingDegree);out.writeInt(satelliteDistance);out.writeInt(measureDiff);out.writeInt(expandDuration);out.writeString(Boolean.toString(closeItemsOnClick));}public static final Parcelable.Creator
 
   CREATOR = new Parcelable.Creator
  
   () {public SavedState createFromParcel(Parcel in) {return new SavedState(in);}public SavedState[] newArray(int size) {return new SavedState[size];}};}
