Question

这是我的代码：

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_business_details, menu);

        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                finish();
                return true;
            case R.id.action_share:
                try {
                    shareBusinessCard();

                } catch (Exception e) {
                    e.printStackTrace();
                }
                return true;

        }
        return super.onOptionsItemSelected(item);
    }

这在Lollipop和其他版本中完美运行，但在Marshmallow中没有。

这是菜单xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".DashboardActivity">


    <item
        android:id="@+id/action_share"
        android:icon="@drawable/ic_profile_share"
        android:orderInCategory="100"
        android:title="@string/action_share"
        app:showAsAction="ifRoom" />


</menu>

我使用工具栏作为操作栏，这是

的xml

Answer 1

如果您将菜单从片段中添加setHasOptionsMenu(true);到onCreate();或onCreateView();

操作栏菜单在Android M（marshmallow）设备中不可见
