<item
       android:checkable="true"
       android:id="@+id/action_disable_keyboard"
       android:title="@string/disable_keyboard"
       app:showAsAction="ifRoom"
       ></item>

checkable只对toolbar应用有效，否则无法看到checkbox。

    @Override
    public void setCheckable(boolean checkable) {
        if (!checkable && mRadioButton == null && mCheckBox == null) {
            return;
        }

        // Depending on whether its exclusive check or not, the checkbox or
        // radio button will be the one in use (and the other will be otherCompoundButton)
        final CompoundButton compoundButton;
        final CompoundButton otherCompoundButton;

        if (mItemData.isExclusiveCheckable()) {
            if (mRadioButton == null) {
                insertRadioButton();
            }
            compoundButton = mRadioButton;
            otherCompoundButton = mCheckBox;
        } else {
            if (mCheckBox == null) {
                insertCheckBox();
            }
            compoundButton = mCheckBox;
            otherCompoundButton = mRadioButton;
        }

        if (checkable) {
            compoundButton.setChecked(mItemData.isChecked());

            if (compoundButton.getVisibility() != VISIBLE) {
                compoundButton.setVisibility(VISIBLE);
            }

            // Make sure the other compound button isn't visible
            if (otherCompoundButton != null && otherCompoundButton.getVisibility() != GONE) {
                otherCompoundButton.setVisibility(GONE);
            }
        } else {
            if (mCheckBox != null) {
                mCheckBox.setVisibility(GONE);
            }
            if (mRadioButton != null) {
                mRadioButton.setVisibility(GONE);
            }
        }
    }

最后定位到

private void insertCheckBox() {
LayoutInflater inflater = getInflater();
mCheckBox =
(CheckBox) inflater.inflate(R.layout.abc_list_menu_item_checkbox,
this, false);
addContentView(mCheckBox);
}

因此得到如下解决办法

新建布局 设置buttontinit

abc_list_menu_item_checkbox.xml

如果使用attr+动态设置主题则需要改成appcompatbox,
