android – 在ListView中获取绝对视图位置

概述我试图让一个d出窗口出现在ListView内部单击的项目上方/下方. 然而,问题是从OnItemClick方法进入的View只给了我X& Y值相对于ListView本身.我还检查了ListView,这也给了我x = 0 y = 0,尽管它上面还有其他视图. 我遍历了hierarchyviewer中的所有值,但没有看到我正在寻找的值. (而不是我在重新开始工作时遇到重大问题). 有什么建议？ @Ov 我试图让一个d出窗口出现在ListVIEw内部单击的项目上方/下方.
然而,问题是从OnItemClick方法进入的VIEw只给了我X& Y值相对于ListVIEw本身.我还检查了ListVIEw,这也给了我x = 0 y = 0,尽管它上面还有其他视图.

我遍历了hIErarchyvIEwer中的所有值,但没有看到我正在寻找的值. (而不是我在重新开始工作时遇到重大问题).

有什么建议？

@OverrIDepublic voID onListItemClick(ListVIEw ListVIEw,VIEw vIEw,int position,long ID) {    LayoutInflater inflater = getLayoutInflater(null);    PopupWindow quickRail = new PopupWindow(            inflater.inflate(R.layout.quanitity_controls,null),vIEw.getMeasureDWIDth(),vIEw.getMeasuredHeight());    int[] location = {            0,0    };    // This doesn't place this window right on top of the vIEw    quickRail.showAtLocation(vIEw,Gravity.CENTER,location[1]);}

列表中的两个项目都使Popup出现在同一个位置.

解决方法 这应该工作

//Activity windows heightint totalHeight = getwindowManager().getDefaultdisplay().getHeight();int[] location = new int[2];v.getLocationOnScreen(location);

位置数组应具有视图的x和y值.
‘v’是onItemClickListener上传递的视图对象.

我添加了一些我用于项目的部分.它可能会有所帮助.我在ListvIEw的顶部有一个 *** 作栏,这段代码似乎运行正常.

要求是在列表项的顶部或下方放置一个小菜单.因此,当选择一个项目时,我检查所选列表项是否在屏幕的上半部分,如果是这样,则将菜单放在列表项目下面,否则将其放在列表项目的顶部.
这是代码

ListItem单击代码

ListVIEw.setonItemClickListener(new OnItemClickListener() {    public voID onItemClick(AdapterVIEw<?> parent,long ID) {        showquickactionMenu(position,vIEw);    }   });private voID showquickactionMenu(int pos,VIEw v){    LayoutInflater inflater =             (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);    //This is just a vIEw with buttons that act as a menu.      VIEw popupVIEw = inflater.inflate(R.layout.ticket_List_menu,null);    popupVIEw.findVIEwByID(R.ID.menu_vIEw).setTag(pos);    popupVIEw.findVIEwByID(R.ID.menu_change_status).setTag(pos);    popupVIEw.findVIEwByID(R.ID.menu_add_note).setTag(pos);    popupVIEw.findVIEwByID(R.ID.menu_add_attachment).setTag(pos);    window = PopupHelper.newBasicPopupWindow(TicketList.this);    window.setContentVIEw(popupVIEw);    int totalHeight = getwindowManager().getDefaultdisplay().getHeight();    int[] location = new int[2];    v.getLocationOnScreen(location);    if (location[1] < (totalHeight / 2.0)) {        PopupHelper.showlikequickaction(window,popupVIEw,v,getwindowManager(),PopupHelper.UPPER_HALF);    } else {        PopupHelper.showlikequickaction(window,PopupHelper.LOWER_HALF);    }   }

这是我使用的PopupHelper类

public class PopupHelper {    public static final int UPPER_HALF = 0;    public static final int LOWER_HALF = 1;    public static PopupWindow newBasicPopupWindow(Context context) {        final PopupWindow window = new PopupWindow(context);        // when a touch even happens outsIDe of the window        // make the window go away        window.settouchInterceptor(new OntouchListener() {            public boolean ontouch(VIEw v,MotionEvent event) {                if(event.getAction() == MotionEvent.ACTION_OUTSIDE) {                    window.dismiss();                    return true;                }                return false;            }        });        window.setWIDth(WindowManager.LayoutParams.WRAP_CONTENT);        window.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);        window.settouchable(true);        window.setFocusable(true);        window.setoutsIDetouchable(true);        window.setBackgroundDrawable(                new colorDrawable(androID.R.color.darker_gray));                return window;    }    /**     * displays like a quickaction from the anchor vIEw.     *      * @param xOffset     *            offset in the X direction     * @param yOffset     *            offset in the Y direction     */     public static voID showlikequickaction(PopupWindow window,VIEw root,VIEw anchor,WindowManager windowManager,int xOffset,int yOffset,int section) {         //window.setAnimationStyle(R.style.Animations_GrowFromBottomright);         int[] location = new int[2];         anchor.getLocationOnScreen(location);         Rect anchorRect = new Rect(location[0],location[1],location[0] +                  anchor.getWIDth(),location[1] + anchor.getHeight());         root.measure(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);         int rootWIDth = root.getMeasureDWIDth();         int rootHeight = root.getMeasuredHeight();         int screenWIDth = windowManager.getDefaultdisplay().getWIDth();         int screenHeight = windowManager.getDefaultdisplay().getHeight();         int xPos = ((screenWIDth - rootWIDth) / 2) + xOffset;         int yPos = anchorRect.top - rootHeight + yOffset;         xPos = (screenWIDth - rootWIDth);         if(section == UPPER_HALF){             yPos = anchorRect.top + anchor.getMeasuredHeight();             } else {             yPos = anchorRect.top - rootHeight;         }         window.showAtLocation(anchor,Gravity.NO_GraviTY,xPos,yPos);    }}
