android popupwindow位置顯示

標籤：

1、在控制項的上方：

private void showPopUp(View v) {                LinearLayout layout = new LinearLayout(this);                layout.setBackgroundColor(Color.GRAY);                TextView tv = new TextView(this);                tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));                tv.setText("I‘m a pop -----------------------------!");                tv.setTextColor(Color.WHITE);                layout.addView(tv);                popupWindow = new PopupWindow(layout,120,120);                                popupWindow.setFocusable(true);                popupWindow.setOutsideTouchable(true);                popupWindow.setBackgroundDrawable(new BitmapDrawable());                                int[] location = new int[2];                v.getLocationOnScreen(location);                                popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0], location[1]-popupWindow.getHeight());        }

在控制項的其他方向上顯示只需修改最後一行代碼即可，如：

popupWindow.showAsDropDown(v);

在下方，其它方法

int[] location = new int[2];  v.getLocationOnScreen(location);popupWindow.showAtLocation(v, Gravity.TOP, 0,location[1]+v.getHeight());

3、左邊：

popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0]-popupWindow.getWidth(), location[1]);

4、右邊：

popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0]+v.getWidth(), location[1]);
