在工具栏中的 SearchView 打开的情况下更新 RecyclerView 视图后关闭软键盘？

如何解决在工具栏中的 SearchView 打开的情况下更新 RecyclerView 视图后关闭软键盘？

8/6/21 在下面添加了其他代码更新，但也未成功。令人惊讶的是，以前的 stackoverflow 成员已经尝试过很多潜在的解决方案，但没有一个适用于我的用例......除了 Android 令人沮丧。

我正在尝试添加代码以在这些用户事件后关闭软键盘：

我工具栏中的 SearchView 从 RecyclerView 列表中的全套 CardView 中返回满足用户搜索文本条件的 CardView 过滤列表。
用户开始向左滑动以从过滤列表中删除过滤的 CardView 之一。
用户通过使用 DialogFragment 对话框单击“确定”来确认 Cardview 删除。
视图按预期更新并返回过滤后的剩余 CardView
工具栏正确显示 SearchView 仍然打开，搜索文本仍然显示在 mSearchView 的 EditText 行

但是当过滤的列表视图更新时，软键盘会弹出。那么如何在视图更新时防止软键盘弹出？

我在 MainActivity 中尝试的代码不起作用：

1)
// this keeps the soft keyboard from opening but it closes the 
// SearchView in the Toolbar and I'd like to keep it open for the user
// with the user's 
if (mSearchView != null) {         
    mSearchView.clearFocus();  
}

2)
// Check if no view has focus:
View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = 
    (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(),0);
}

8/6/21 更新：

这些在 removeItem() 中都不起作用，使用“View viewRemove = MainActivity.this.getCurrentFocus();”

mSearchEditText.onEditorAction(EditorInfo.IME_ACTION_GO);
immMain.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY,0);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
immMain.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),inputMethodManager.HIDE_NOT_ALWAYS);
immMain.hideSoftInputFromWindow(viewRemove.getWindowToken(),0);             
immMain.hideSoftInputFromWindow(mSearchView.getWindowToken(),0);             
immMain.hideSoftInputFromWindow(mSearchEditText.getWindowToken(),0);
immMain.hideSoftInputFromWindow(viewRemove.getApplicationWindowToken(),0);
immMain.hideSoftInputFromWindow(mSearchView.getApplicationWindowToken(),0);
immMain.hideSoftInputFromWindow(mSearchEditText.getApplicationWindowToken(),0);

我在 DialgoFragment 中尝试的代码不起作用：

1)
InputMethodManager imm =
    (InputMethodManager) rootView.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isActive()) {
    imm.toggleSoftInput(0,InputMethodManager.HIDE_NOT_ALWAYS);
}

2)
View view = getActivity().getCurrentFocus();
if (view == null) view = new View(activity); {
    InputMethodManager imm = (InputMethodManager) 
        getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);    
    if (imm == null) { 
        return; 
    }
    else {
        imm.hideSoftInputFromWindow(view.getWindowToken(),0);
    }
}
 
3)
View view = getActivity().getCurrentFocus();
if (view == null) view = new View(activity); {
    InputMethodManager imm = (InputMethodManager) 
        getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
    if (imm == null) {
        return; }
    else {
        imm.hideSoftInputFromWindow(view.getWindowToken(),InputMethodManager.HIDE_NOT_ALWAYS);
    }

8/6/21 Update:

These also did not work in the Fragement:

((MainActivity) getActivity()).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
Objects.requireNonNull(this.getDialog().getWindow()).setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

What am I missing here?


MainActivity

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.mainactiv_menu,menu);
    searchItem = menu.findItem(R.id.action_search);
    menu.findItem(R.id.action_search).setVisible(false);

    SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);
    if (searchItem != null) {
        mSearchView = (SearchView) searchItem.getActionView();

        // Sets up a new a new SearchViewFocusListener so it can capture
        // a Back Button press by the member.
        mSearchView.setOnQueryTextFocusChangeListener(new SearchViewFocusListener(searchItem));
        // Associate the SearchView with the searchable configuration using
        // setSearchableInfo(getSearchableInfo).
        if (mSearchView != null) {
            mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            EditText mSearchEditText = mSearchView.findViewById(androidx.appcompat.R.id.search_src_text);                mSearchEditText.setInputType(android.text.InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

    
        // use the link to EditText of the SearchView so that a
        // TextWatcher can be used.
        mSearchEditText.addTextChangedListener(new TextWatcher() {
        
        @Override
        public void afterTextChanged(Editable s) {
            ... // search criteria code
            if (!mSearchView.isIconified() && searchList.size() > 0) {
                cardsAdapter.setFilter(searchList,s.toString());
                if (immMain != null) { 
                    immMain.hideSoftInputFromWindow(mSearchView.getWindowToken(),0);
                }
  return super.onCreateOptionsMenu(menu);
}     
               
DeleteCardViewFragment

public class DeleteCardViewFragment extends DialogFragment {

    public DeleteCardViewFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {

        if (getActivity() != null) {
            Button btnOK = rootView.findViewById(R.id.btnOK);
            btnOK.setOnClickListener(v -> {
               ((MainActivity) getActivity()).removeItem(card);
            }
            // close soft keyboard from the Fragment code was unsuccessfully tried here
        }
        dismiss(); 

   MainActivity removeItem code:

   public void removeItem(@NonNull final Card card) {
       // code to remove the CardView from the RecyclerView list
       mRecyclerView.scrollToPosition(0);
       // MainActivity code was unsuccessfully added here to try to close the soft keyboard
   }
   // please note that a regular left-swipe by the user on a CardView,// without an active SearchView open works as expected;  that is,the 
   // CardView is deleted and the user is returned to the updated 
   // CardView list and the soft keyboard does not open.  So the 
   // SearchView is probably causing the problem and something to do 
   // with the focus after the view is updated.

解决方法

在片段中尝试使用此代码关闭键盘：

   /*--for hiding keyboard on click--*/
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
        //Find the currently focused view,so we can grab the correct window token from it.
        View view = getActivity().getCurrentFocus();
        //If no view currently has focus,create a new one,just so we can grab a window token from it
        if (view == null) {
            view = new View(getActivity());
        }
        assert imm != null;
        imm.hideSoftInputFromWindow(view.getWindowToken(),0);

Activity 中键盘关闭的代码：

 /*--for hiding keyboard on click--*/
        InputMethodManager imm=(InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
        //Find the currently focused view,so we can grab the correct window token from it.
        View view = getCurrentFocus();
        //If no view currently has focus,just so we can grab a window token from it
        if (view == null){
            view = new View(this);
        }
        assert imm != null;
        imm.hideSoftInputFromWindow(view.getWindowToken(),0);

在 MainActivity 的清单中添加此代码

android:windowSoftInputMode="stateAlwaysHidden

您可以尝试的一些解决方案

使用 stateHidden 设置 windowSoftInputMode

<activity android:name=".MainActivity" android:windowSoftInputMode="stateHidden">

将这些属性添加到父视图中

android:focusable="true" android:focusableInTouchMode="true"
