Question

您好我使用了如下的searchview，

@Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        menu.clear();
        inflater.inflate(R.menu.all_menu, menu);
        SearchManager manager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        searchView.setSearchableInfo(manager.getSearchableInfo(getActivity().getComponentName()));
        searchTextView = (AutoCompleteTextView) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
        try {
            Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
            mCursorDrawableRes.setAccessible(true);
            mCursorDrawableRes.set(searchTextView, R.drawable.cursor); //This sets the cursor resource ID to 0 or @null which will make it visible on white background
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (searchView != null) {
            searchView.setQueryHint(getString(R.string.search));
            searchView.setOnQueryTextListener(this);
        }
        mMenu = menu;
        setNotificationCount(mMenu);
    }

并且我使用以下代码使通知计数无效，

 getSupportActionBar().invalidateOptionsMenu();

但是菜单无效将关闭打开的键盘。即使在操作栏菜单无效后我也想保留键盘状态。所以我试图使用下面的代码保留键盘状态，

 KeyboardVisibilityEvent.setEventListener(getActivity(), new KeyboardVisibilityEventListener() {
                        @Override
                        public void onVisibilityChanged(boolean isOpen) {
                            if(!isFristTime){
                                Log.d("ss","keyboard status before validated "+isKeyboardOpened);
                                isKeyboardOpened = isOpen;
                                isFristTime = true;
                            }
                        }
                    });
                    getSupportActionBar().invalidateOptionsMenu();
                    Log.d("ss","keyboard status after validated "+isKeyboardOpened);
                    if(isKeyboardOpened){
                        final Handler handler = new Handler();
                        handler.postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                try {
                                    Log.d("ss","keyboard status in try ");
                                    Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
                                    mCursorDrawableRes.setAccessible(true);
                                    mCursorDrawableRes.set(searchTextView, R.drawable.cursor); //This sets the cursor resource ID to 0 or @null which will make it visible on white background
                                    BDevice.showSoftKeyboard(getActivity(), searchTextView);
                                    isKeyboardOpened = false;
                                    getSupportActionBar().invalidateOptionsMenu();
                                } catch (Exception e) {
                                    Log.d("ss","keyboard status in catch ");
                                    e.printStackTrace();
                                }
                            }
                        }, 1000);
                    }

但这不起作用。现在我想打开软键盘，如果它打开，然后使菜单无效。你可以建议我在菜单无效后保留键盘状态吗？

我找到了解决方案。每当验证操作栏菜单onCreateOptionsMenu获得调用。因此，我在第一次打开键盘时存储键盘状态，并在验证后检查onCreateOptionsMenu中的键盘状态。然后我用来扩展搜索视图并以编程方式打开软键盘，如下所示，

全局变量

private boolean isFristTime = false, isKeyboardOpened = false;
private String mCurrentQuery = "";

然后我的代码在onCreateOptionsMenu方法

 if(isKeyboardOpened) {
                searchView.setIconified(false);
                searchItem.expandActionView();
                searchView.requestFocus();
                if(!TextUtils.isEmpty(mCurrentQuery)){
                    searchView.setQuery(mCurrentQuery, false);
                }else{
                    searchView.setQueryHint(getString(R.string.search));
                }
                searchView.setIconifiedByDefault(true);
                BDevice.showSoftKeyboard(getActivity(), searchTextView);
                isKeyboardOpened = false;
            }

我正在验证之前启动键盘，如下所示，

KeyboardVisibilityEvent.setEventListener(getActivity(), new KeyboardVisibilityEventListener() {
                        @Override
                        public void onVisibilityChanged(boolean isOpen) {
                            if(!isFristTime){

                                isKeyboardOpened = isOpen;
                                isFristTime = true;
                            }
                        }
                    });

                    getSupportActionBar().invalidateOptionsMenu();

并在onQueryTextChange方法中获取我的查询

   @Override
        public boolean onQueryTextChange(String newText) {
           mCurrentQuery = newText;
          return true;
        }

快乐编码......
