contentView); 如果创建PopupWindow的时候没有指定高宽，那么showAsDropDown默认只会向下弹出显示，这种情况有个最明显的缺点就是：弹窗口可能被屏幕截断，显示不全，所以需要使用到另外一个方法showAtLocation...calculatePopWindowPos(view, windowContentViewRoot); int xOff = 20；// 可以自己调整偏移 windowPos[0] -= xOff; popupwindow.showAtLocation
= null) { mPopupWindow.showAtLocation(parent, Gravity.NO_GRAVITY, location[0], location...= null) { mPopupWindow.showAtLocation(view, Gravity.NO_GRAVITY, location[0], location...= null) { mPopupWindow.showAtLocation(view, Gravity.NO_GRAVITY, location[0] - getWidth...} return this; } public CommonPopWindow showAtLocation(View anchor, int gravity, int...= null) { mPopupWindow.showAtLocation(anchor, gravity, x, y); } return this
public void dismiss() { backgroundAlpha(1f); } }); recomPopup.showAtLocation...ShowListener showListener; private DismissListener dismissListener; @Override public void showAtLocation...(View parent, int gravity, int x, int y) { super.showAtLocation(parent, gravity, x, y); if
sendMsgPopup = new SendMsgPopupWindow(NewsDetailsActivity.this); } //设置处于底部 sendMsgPopup.showAtLocation...// 评论框消息的同时把软键盘关闭 KeyBoardUtils.closeKeybord(editText, mContext); } public void showAtLocation...this.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED); // 在显示输入法之后调用，否则popupwindow会在窗口底层 super.showAtLocation
初看其实很简单，根据A的位置和大小，算出PopupWindow的位置，调用showAtLocation方法即可实现在A正上方弹出。...; int[] location = new int[2]; v.getLocationOnScreen(location); popupWindow.showAtLocation...这里写图片描述 可以发现，我们的PopupWindow并没有跟随一起滚动，这是因为在调用showAtLocation的时候，PopupWindow的位置已经确定了，所以并不会跟着A的滚动而滚动。
popupWindow.showAsDropDown(view, 0, -view.getHeight() - popupWindow.getHeight()); popupWindow.showAtLocation...location[1]; switch (type) { case TOP2TOP: popupWindow.showAtLocation...x, y); break; case TOP2BOTTOM: popupWindow.showAtLocation...view.getHeight()); break; case BOTTOM2TOP: // popupWindow.showAtLocation...(view, Gravity.CLIP_HORIZONTAL, 0, 0); popupWindow.showAtLocation(view, Gravity.NO_GRAVITY
而PopupWindow似乎就提供了showAsDropDown方法（请忽略showAtLocation，这边说的是相对于View显示），这~~就有点尴尬了。....); //又或者使用showAtLocation根据屏幕来定位 mWindow.showAtLocation(...); Gravity.LEFT(Gravity.START)：相对于View左对齐；...Gravity.CENTER：在showAsDropDown()中是跟 Gravity.LEFT一样，在showAtLocation()中Gravity.CENTER才有效果 得到效果
最近发现了在Android N(Android 7.0，7.1)上Popwindow的一个位置显示问题，当指定PopupWindow高度为MATCH_PARENT时使用showAsDropDown或者是showAtLocation...mPopupWindow.setHeight(screenHeight - offsetY); // 重新设置 PopupWindow 的高度 } mPopupWindow.showAtLocation
PopupWindow显示在这个控件的下方；而showAtLocation是相对于屏幕，可以通过设置Gravity来指定PopupWindow显示在屏幕的那个位置。...我们再来看showAtLocation: 因为这个方法是PopupWindow的显示相对于屏幕，所以传入的View也是只要这个屏幕的就可以，因为这个View的传入也只是为了拿到Window Token。...//这个方法最后还是等于调用了另外一个showAtLocation方法, //传入view只是为了拿到token //x,y同样是x和y轴的偏移值 public void showAtLocation(...：popupWindow.showAtLocation(view, Gravity.RIGHT | Gravity.BOTTOM, 0, 0); ?...如果我们设置为：popupWindow.showAtLocation(view, Gravity.TOP, 0, 0); ? 我们发现PopupWindow并没有在statusbar的上面。

showAtLocation(View parent, int gravity, int x, int y)：将PopupWindow显示在指定父容器View内的指定位置。...showAtLocation(View parent, int gravity, int x, int y)：将PopupWindow显示在指定父容器View内的指定位置。
