在工具栏中的 SearchView 打开的情况下更新 RecyclerView 视图后关闭软键盘? [英] Close soft keyboard after RecyclerView view is updated with SearchView in Toolbar open?
问题描述
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.
8/6/21 Added additional code updates below that also have been unsuccessful. Amazing, so many potential solutions that previous stackoverflow members have tried and none work for my use case...beyond Android frustrated.
我正在尝试添加代码以在这些用户事件后关闭软键盘:
I am trying to add code to close the soft keyboard after these user events:
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.
A SearchView in my Toolbar returns a filtered list of CardViews that meet the user's search text criteria, from the full set of CardViews in the RecyclerView List.
用户开始向左滑动以从过滤列表中删除过滤的 CardView 之一.
User initiates a left-swipe to delete one of the filtered CardViews from the filtered list.
用户通过单击确定"确认 Cardview 删除；使用 DialogFragment 对话框.
User confirms the Cardview delete by clicking "Ok" with a DialogFragment dialog.
视图按预期更新并返回过滤后的剩余 CardView
The view updates as expected and returns the remaining filtered CardViews
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
The Toolbar is correctly showing the SearchView still open with the search text still showing on the mSearchView's EditText line
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?
But the softkeyboard is popping open when the filtered list view is updated. So how do I keep the softkeyboard from popping open when the view updates?
我在 MainActivity 中尝试的代码不起作用:
Code I tried in the MainActivity that did not work:
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();"
None of these worked in the removeItem(), with "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:
Code I tried in the DialgoFragment that did not work:
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.
推荐答案
在片段中试试这个键盘关闭代码:
Try this code for keyboard close in fragment:
/*--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:
This code for keyboard close in Activity:
/*--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, create a new one, 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);
在清单中为 MainActivity
android:windowSoftInputMode="stateAlwaysHidden
