弹出菜单的宽度 - 如何更改

Question

我使用以下代码显示弹出菜单

PopupMenu popupMenu = new PopupMenu(MainActivity.this, v);
                      popupMenu.getMenuInflater().inflate(R.menu.popupmenu, popupMenu.getMenu());
                      popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {

                   @Override
                   public boolean onMenuItemClick(MenuItem item) {
                    Toast.makeText(MainActivity.this,
                      item.toString(),
                      Toast.LENGTH_LONG).show();
                    return true;
                   }
                  });

                      popupMenu.show();
                  }

但菜单覆盖了我的很多屏幕区域。如何指定弹出菜单的大小？
