android– 上下文 *** 作菜单无法在视觉上超过片段中的 *** 作栏位置

概述我有一个包含带有项目的ListView的片段的Activity,用户可以在其上单击并调用上下文 *** 作模式.我喜欢发生的是documentation所说的：Thecontextualactionbarisnotnecessarilyassociatedwiththeactionbar.Theyoperateindependently,eventhoughthecontextual

我有一个包含带有项目的ListVIEw的片段的Activity,用户可以在其上单击并调用上下文 *** 作模式.

我喜欢发生的是documentation所说的：

The contextual action bar is not necessarily associated with the
action bar. They operate independently, even though the contextual
action bar visually overtakes the action bar position.

但是,这是我目前正在经历的行为.截至目前,上下文 *** 作模式显示在Actionbar上方,如下图所示.

到目前为止我没有成功的尝试：

>将ActionMode逻辑从Fragment移动到主机Activity.
>设置< item name =“windowActionModeOverlay”> true< / item>在我的主题.
>调用getActivity().getMenuInflater()而不是mode.getMenuInflater().

这是我调用Contextual Action Menu的代码

public class NotesFragment extends Fragment implements VIEw.OnClickListener{    private ActionMode mActionMode;    @OverrIDe    public voID checkBoxChecked(Note which) {        if (mActionMode == null)            mActionMode = getActivity().startActionMode(mActionModeCallback);    }    private ActionMode.Callback mActionModeCallback = new ActionMode.Callback() {        // Called when the action mode is created; startActionMode() was called        @OverrIDe        public boolean onCreateActionMode(ActionMode mode, Menu menu) {            // Inflate a menu resource provIDing context menu items            MenuInflater inflater = mode.getMenuInflater();            inflater.inflate(R.menu.context, menu);            return true;        }        // Called each time the action mode is shown.         // Always called after onCreateActionMode, but        // may be called multiple times if the mode is invalIDated.        @OverrIDe        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {            return false; // Return false if nothing is done        }        // Called when the user selects a contextual menu item        @OverrIDe        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {            switch (item.getItemID()) {                case R.ID.context_delete:                    //Do work unrelated to topic                    mode.finish(); // Action picked, so close the CAB                    return true;                case R.ID.context_move:                    //Do work unrelated to topic                    mode.finish(); // Action picked, so close the CAB                    return true;                default:                    return false;            }        }        // Called when the user exits the action mode        @OverrIDe        public voID onDestroyActionMode(ActionMode mode) {            mActionMode = null;        }    };}

编辑：
这是Fragment所在的Activity：

public class MainActivity extends ActionBaractivity implements DialogFragmentMoveNote.DialogFragmentMoveNoteListener,        DialogFragmentRemoveNote.DialogFragmentRemoveNoteListener, DialogFragmentAddNewFolder.DialogFragmentAddNewFolderListener,        DialogFragmentDeleteFolder.DialogFragmentDeleteFolderListener {    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);    }    @OverrIDe    public voID onAddNewFolderPositiveClick(Folder folder) {        //Tell the fragment to do work    }    @OverrIDe    public voID onRemoveNotesPositiveClick() {        //Tell the fragment to do work    }    @OverrIDe    public voID onMoveNotePositiveClick(String chosenFolder) {        //Tell the fragment to do work    }    @OverrIDe    public voID onDeleteFolderPositiveClick() {        //Tell the fragment to do work    }    private voID displayNoteDetailsFromWidget(String noteID){        //Tell the fragment to do work    }}

为什么上下文 *** 作菜单在视觉上不会超过Actionbar,因为文档状态应该是什么？

解决方法:

对此的解决方案是添加

<item name="androID:windowActionModeOverlay">true</item>

到我的主题,现在看起来像

<!-- Base application theme. --><style name="Apptheme" parent="theme.AppCompat.light.DarkActionbar">    <!-- Customize your theme here. -->    <item name="androID:windowActionModeOverlay">true</item></style>

看完this answer后我找到了解决方案
