Close virtual keyboard on button press

问题:

I have an Activity with an EditText, a button and a ListView. The purpose is to type a search screen in the EditText, press the button and have the search results populate this list.

This is all working perfectly, but the virtual keyboard is behaving strange.

If I click the EditText, I get the virtual keyboard. If I click the "Done" button on the virtual keyboard, it goes away. However, if I click my search button before clicking "Done" on the virtual keyboard, the virtual keyboard stays and I can't get rid of it. Clicking the "Done" button does not close the keyboard. It changes the "Done" button from "Done" to an arrow and remains visible.

Thanks for your help

InputMethodManager inputManager = (InputMethodManager)
                                  getSystemService(Context.INPUT_METHOD_SERVICE); 

inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
                                     InputMethodManager.HIDE_NOT_ALWAYS);

I put this right after the onClick(View v) event.

You need to import android.view.inputmethod.InputMethodManager;

The keyboard hides when you click the button.

mMyTextView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            // hide virtual keyboard
            InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(m_txtSearchText.getWindowToken(), 
                                      InputMethodManager.RESULT_UNCHANGED_SHOWN);
            return true;
        }
        return false;
    }
});

Use Below Code

your_button_id.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        try  {
            InputMethodManager imm = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        } catch (Exception e) {

        }
    }
});

You should implement OnEditorActionListener for your EditView

public void performClickOnDone(EditView editView, final View button){
    textView.setOnEditorActionListener(new OnEditorActionListener() {

        @Override
        public boolean onEditorAction(EditView v, int actionId, KeyEvent event) {
            hideKeyboard();
            button.requestFocus();
            button.performClick();
            return true;
        }
    });

And you hide keyboard by:

public void hideKeybord(View view) {
    inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),
                                  InputMethodManager.RESULT_UNCHANGED_SHOWN);
}

You should also fire keyboard hiding in your button using onClickListener

Now clicking 'Done' on virtual keyboard and button will do the same - hide keyboard and perform click action.

Add the following code inside your button click event:

InputMethodManager inputManager = (InputMethodManager) getSystemService(this.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

回答6:

Since you have only one edit text then just call action done for that edit text inside your button click and the rest is handled by the system. If you had more than one edittext then this would not be so efficent because you have to get the focused edittext first. But in your case it will work perfectly

myedittext.onEditorAction(EditorInfo.IME_ACTION_DONE)

For Activity,

InputMethodManager imm = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

For Fragments, use getActivity()

getActivity().getSystemService();

getActivity().getCurrentFocus();

InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);

This solution works perfect for me:

private void showKeyboard(EditText editText) {
    editText.requestFocus();
    editText.setFocusableInTouchMode(true);
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(editText, InputMethodManager.RESULT_UNCHANGED_SHOWN);
    editText.setSelection(editText.getText().length());
}

private void closeKeyboard() {
    InputMethodManager inputManager = (InputMethodManager) getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.RESULT_UNCHANGED_SHOWN);
}

回答9:

Try this...

1. For Showing keyboard

   editText.requestFocus();
   InputMethodManager imm = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
   imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
   

2. For Hide keyboard

   InputMethodManager inputManager = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE); 
   inputManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
   

回答10:

View view = this.getCurrentFocus();
if (view != null) {
InputMethodManager imm =(InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);enter code here}

回答11:

You use this code in your button click event

// 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);
}

回答12:

Crash Null Point Exception Fix: I had a case where the keyboard might not open when the user clicks the button. You have to write an if statement to check that getCurrentFocus() isn't a null:

            InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if(getCurrentFocus() != null) {
            inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

回答13:

Kotlin example:

val inputMethodManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

from Fragment:

inputMethodManager.hideSoftInputFromWindow(activity?.currentFocus?.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)

from Activity:

inputMethodManager.hideSoftInputFromWindow(currentFocus?.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)

If you set android:singleLine="true", automatically the button hides the keyboard¡
