【中文标题】长按网页视图的水平菜单充气机【英文标题】：Horizontal menu inflater on long click for web view 【发布时间】：2018-01-14 10:13:18 【问题描述】：我在 longClick 上的 webview 选择有问题。我已经实现了在 longClick 上启动的自定义菜单。但默认菜单也在启动。我正在尝试自定义默认菜单，但我不知道如何捕获用户对某个项目的点击。
我尝试了以下操作，但菜单变得垂直并隐藏了选择，因此我无法选择更多单词或更改选择。
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
/*
public void inflate (int menuRes, Menu menu)
Inflate a menu hierarchy from the specified XML resource. Throws InflateException if there is an error.
Parameters
menuRes : Resource ID for an XML layout resource to load (e.g., R.menu.main_activity)
menu : The Menu to inflate into. The items and submenus will be added to this Menu.
*/
inflater.inflate(R.menu.menu, menu);
@Override
public boolean onContextItemSelected(MenuItem item)
// Handle the menu item selection
switch(item.getItemId())
case R.id.dict_menu:
// Render the page again
Toast.makeText(mContext,"dict_menu",Toast.LENGTH_SHORT).show();
return true;
case R.id.q_menu:
Toast.makeText(mContext,"q_menu",Toast.LENGTH_SHORT).show();
return true;
case R.id.hi_menu:
Toast.makeText(mContext,"hi_menu",Toast.LENGTH_SHORT).show();
return true;
default:
super.onContextItemSelected(item);
return false;
菜单xml如下。
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal">
<item android:id="@+id/dict_menu"
android:title="قاموس" />
<item android:id="@+id/q_menu"
android:title="اقتباس" />
<item android:id="@+id/hi_menu"
android:title="تظليل" />
</menu>
因此，而不是得到这个结果：（当我没有实现以下方法时，我得到了这个结果：onCreateContextMenu，onContextItemSelected 使我能够在选择菜单项时捕获）
我得到以下信息：
当我使用以下代码时收到第一个屏幕截图：
@Override
public void onActionModeStarted(ActionMode mode)
System.out.println("onActionModeStarted");
if (mActionMode == null)
mActionMode = mode;
//mode.setTitle("Dictionary");
Menu menu = mode.getMenu();
menu.clear();
mode.getMenuInflater().inflate(R.menu.menu, menu);//mode.getMenuInflater().inflate(myMenu, menu);
//System.out.println("onActionModeStarted");
super.onActionModeStarted(mode);
public void onContextualMenuItemClicked(MenuItem item)
System.out.println("onContextualMenuItemClicked");
switch (item.getItemId())
case R.id.dict_menu:
// do some stuff
System.out.println("dict_menu");
Toast.makeText(mContext,"dict_menu",Toast.LENGTH_SHORT).show();
break;
case R.id.hi_menu:
// do some different stuff
System.out.println("hi_menu");
Toast.makeText(mContext,"hi_menu",Toast.LENGTH_SHORT).show();
break;
case R.id.q_menu:
// do some different stuff
System.out.println("q_menu");
Toast.makeText(mContext,"q_menu",Toast.LENGTH_SHORT).show();
break;
default:
// ...
super.onContextItemSelected(item);
break;
// This will likely always be true, but check it anyway, just in case
/*if (mActionMode != null)
mActionMode.finish();
*/
@Override
public void onActionModeFinished(ActionMode mode)
mActionMode = null;
super.onActionModeFinished(mode);
System.out.println("onActionModeFinished");
<?xml version="1.0" encoding="utf-8"?>
<!---<menu xmlns:android="http://schemas.android.com/apk/res/android"-->
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal">
<item android:id="@+id/dict_menu"
android:onClick="onContextualMenuItemClicked"
android:title="قاموس" />
<item android:id="@+id/q_menu"
android:onClick="onContextualMenuItemClicked"
android:title="اقتباس" />
<item android:id="@+id/hi_menu"
android:onClick="onContextualMenuItemClicked"
android:title="تظليل" />
</menu>
这会导致以下错误：

【参考方案1】：在托管您的WebView 的任何活动中，覆盖onActionModeStarted()，操作菜单项，并为每个活动分配侦听器。一个例子：
@Override
public void onActionModeStarted(ActionMode mode)
super.onActionModeStarted(mode);
MenuInflater menuInflater = mode.getMenuInflater();
Menu menu = mode.getMenu();
menu.clear();
menuInflater.inflate(R.menu.menu_custom, menu);
menu.findItem(R.id.custom_one).setOnMenuItemClickListener(new ToastMenuItemListener(this, mode, "One!"));
menu.findItem(R.id.custom_two).setOnMenuItemClickListener(new ToastMenuItemListener(this, mode, "Two!"));
menu.findItem(R.id.custom_three).setOnMenuItemClickListener(new ToastMenuItemListener(this, mode, "Three!"));
private static class ToastMenuItemListener implements MenuItem.OnMenuItemClickListener
private final Context context;
private final ActionMode actionMode;
private final String text;
private ToastMenuItemListener(Context context, ActionMode actionMode, String text)
this.context = context;
this.actionMode = actionMode;
this.text = text;
@Override
public boolean onMenuItemClick(MenuItem item)
Toast.makeText(context, text, Toast.LENGTH_SHORT).show();
actionMode.finish();
return true;
【讨论】：
感谢您的贡献，事实上我已经以类似的方式解决了这个问题，我将发布解决方案。但仍然感谢您的努力。 这个答案之前讨论了如何为TextView 执行此操作（除了上面的内容）。我将其迁移到 ***.com/a/52765047/8298909 此处的答案，因为将这个问题作为一个骗子来结束似乎不合适。【参考方案2】：
这是对我有用的解决方案，希望它对某人有用。
与上一个答案的唯一区别是我动态创建了菜单，导致静态菜单由于某种原因没有响应 menuItemClicked() 函数。
@Override
public void onActionModeStarted(ActionMode mode)
System.out.println("onActionModeStarted");
if (mActionMode == null)
mActionMode = mode;
//mode.setTitle("Dictionary");
Menu menu = mode.getMenu();
menu.clear();
mode.getMenuInflater().inflate(R.menu.menu, menu);
List<MenuItem> menuItems = new ArrayList<>();
// get custom menu item
for (int i = 0; i < menu.size(); i++)
menuItems.add(menu.getItem(i));
menu.clear();
// reset menu item order
int size = menuItems.size();
for (int i = 0; i < size; i++)
addMenuItem(menu, menuItems.get(i), i, true);
//System.out.println("onActionModeStarted");
super.onActionModeStarted(mode);
private void addMenuItem(Menu menu, MenuItem item, int order, boolean isClick)
final MenuItem menuItem = menu.add(item.getGroupId(),
item.getItemId(),
order,
item.getTitle());
menuItem.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
if (isClick)
// set custom menu item click
menuItem.setOnMenuItemClickListener(new OnMenuItemClickListener()
@Override
public boolean onMenuItemClick(MenuItem item)
BookReader.this.menuItemClicked(item);
return true;
);
public void menuItemClicked(MenuItem item)
System.out.println("menuItemClicked");
switch (item.getItemId())
case R.id.dict_menu:
testWV.searchInDict();
if (mActionMode!=null)
mActionMode.finish();
break;
case R.id.hi_menu:
testWV.highlightWord();
break;
case R.id.q_menu:
testWV.copyQuote();
if (mActionMode!=null)
mActionMode.finish();
break;
