推荐答案

您需要设置机器人：可检查菜单，以 true属性并在运行时控制它的选中状态。例如：

You need to set android:checkable property of the menu to true and control its checked state in runtime. Example:

菜单

<item
    android:id="@+id/checkable_menu"
    android:checkable="true"
    android:title="@string/checkable" />

活动

private boolean isChecked = false;

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuItem checkable = menu.findItem(R.id.checkable_menu);
    checkable.setChecked(isChecked);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.checkable_menu:
            isChecked = !item.isChecked();
            item.setChecked(isChecked);
            return true;
        default:
            return false;
    }
}

希望这有助于。
