popupWindow = new PopupWindow(popupwindow的布局,
					LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
			popupWindow.setBackgroundDrawable(new BitmapDrawable());
			popupWindow.setAnimationStyle(R.style.PopupAnimation);
			int publicbenefitxoffInPixels = imgbtn_toaction.getWidth() / 2;
			popupWindow.showAsDropDown(imgbtn_toaction,
					-publicbenefitxoffInPixels, 0);
			popupWindow.update();

R.style.PopupAnimation代码:

<style name="PopupAnimation" parent="android:Animation">
		<item name="android:windowEnterAnimation">@anim/popup_enter</item>
		<item name="android:windowExitAnimation">@anim/popup_exit</item>
	</style>
