LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.pop_window, viewGroup);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 30;
int OFFSET_Y = 30;
// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
popup.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
}
单击时无显示.请帮助我查找错误.
Nothing in showing on click . Please help me in finding Bug .
推荐答案
我认为只要删除if(point！= null)条件，它将起作用
I think just remove if(point!=null) condition it will work
accountInfoLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int[] location = new int[2];
v.getLocationOnScreen(location);
point = new Point();
point.x = location[0];
point.y = location[1];
showPopup(getActivity(),point);
}
}
}
