视图底部的弹出菜单

Question

如何始终在锚视图的底部显示弹出菜单。 这是我用来显示弹出菜单的代码。

 PopupMenu popup = new PopupMenu(activityReference, view, Gravity.NO_GRAVITY);
                popup.getMenuInflater()
                    .inflate(R.menu.popup_menu_event_edit, popup.getMenu());
popup.show();

我尝试将Gravity.NO_GRAVITY更改为Gravity.BOTTOM。 但是它不起作用。

对我有用

PopupMenu attachFilePopup = new PopupMenu(this, view ,Gravity.BOTTOM);
attachFilePopup.inflate(R.menu.attachment_choices);

view =>要显示菜单的底部按钮

attachment_choices.xml

<item
    android:id="@+id/attach_location"
    android:title="@string/send_location"/>

<item
    android:id="@+id/attach_record_voice"
    android:title="@string/attach_record_voice"/>

<item
    android:id="@+id/attach_take_picture"
    android:title="@string/attach_take_picture"/>

<item
    android:id="@+id/attach_choose_picture"
    android:title="@string/attach_choose_picture"/>

<item
    android:id="@+id/attach_choose_file"
    android:title="@string/choose_file"/>

这里的button1是定位视图，表示您要在其中显示菜单的参照

PopupMenu popupMenu = new PopupMenu(context, button1, Gravity.TOP);
popupMenu.getMenuInflater().inflate(R.menu.home_drawer_bottom_nav_menu, popupMenu.getMenu());
popupMenu.show();

使用它为我工作。

popupMenu = new PopupMenu(MainActivity.this, anchorView);
popupMenu.inflate(R.menu.popup_menu);
            popupMenu.show();
