如何获得这样的对话?[已关闭]

您可以使用 Popup menu 为此目的。

在活动中添加此代码。java:

fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PopupMenu popup = new PopupMenu(HomeActivity.this, fab);
                popup.getMenuInflater().inflate(R.menu.menu_home, popup.getMenu());
                popup.setGravity(Gravity.END);

                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {

                        switch (item.getItemId()) {
                            case R.id.action_settings:
                                // your action
                            default:
                                return true;
                        }
                    }
                });

                popup.show();
            }
        });

在里面 style.xml

  <style name="MyPopupMenu" parent="@style/Widget.AppCompat.PopupMenu.Overflow">
    <item name="fontPath">Muli_Regular.ttf</item>
    <item name="android:dropDownHorizontalOffset">0dp</item>
    <item name="android:dropDownVerticalOffset">57dp</item>
</style>

使用此 风格 活动主题为:

<item name="popupMenuStyle">@style/MyPopupMenu</item>
