解决方法: if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { // Android 7.x中,PopupWindow高度为match_parent时,会出现兼容性问题,需要处理兼容性 int[] mLocation = new int[2]; stephenCommonTopTitleView.getTopTitleView().getLocationInWindow(mLocation); int offsetY = mLocation[1] + stephenCommonTopTitleView.getTopTitleView().getHeight(); if (Build.VERSION.SDK_INT >= 25) { // Android 7.1中，PopupWindow高度为 match_parent 时，会占据整个屏幕 //故而需要在 Android 7.1上再做特殊处理 WindowManager wm = (WindowManager) activity.getSystemService(Context.WINDOW_SERVICE); int screenHeight = wm.getDefaultDisplay().getHeight(); centWinShare.setHeight(screenHeight - offsetY); // 重新设置 PopupWindow 的高度 } centWinShare.showAtLocation(stephenCommonTopTitleView.getTopTitleView(), Gravity.NO_GRAVITY, 0, offsetY); } else { centWinShare.showAsDropDown(stephenCommonTopTitleView.getTopTitleView()); } 思路大概是这样 /*if (Build.VERSION.SDK_INT != 24) { //只有24这个版本有问题，好像是源码的问题 showAsDropDown(view); } else { //7.0 showAsDropDown没卵子用 得这么写 int[] location = new int[2]; view.getLocationOnScreen(location); int x = location[0]; int y = location[1]; showAtLocation(view, Gravity.NO_GRAVITY, 0, y + view.getHeight()); //showAsDropDown(view, 0, marginTop); }*/
