Forcing the Soft Keyboard open
I am trying to force the Soft Keyboard open in an Activity and grab everything that is entered as I want to handle the input myself, I don't have an EditText. Currently I have tried this but it does not work. I would like the Soft Keyboardto open below mAnswerTextView (Note: it is a TextView not EditText).
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
// only will trigger it if no physical keyboard is open
mgr.showSoftInput(mAnswerTextView, InputMethodManager.SHOW_IMPLICIT);
try this to force open soft keyboard:
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
then you can to use this code to close the keyboard:
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(_pay_box_helper.getWindowToken(), 0);
You'll probably need to have an editable text area of some kind to take focus. You can probably have one invisible or on a transparent background with no cursor, though. You may need to toy around with the focusability settings for the view.
Use a TextWatcher to check for edits to that EditText with addTextChangedListener, or if you need an even-lower-level hook, set the textview's key listener with its setOnKeyListener() method. See the KeyListener documentation.
Use this call to force the soft keyboard open:
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE))
.showSoftInput(myEditText, InputMethodManager.SHOW_FORCED);
and this one to close it:
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
note that this is really not recommended - forcing the keyboard open is kind of messy. What's your use case that really necessitates your taking user input without a normal edit box and requires eating user input on a key-by-key basis without echoing it back?
To force the keyboard to open I used
this.getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
it worked for me.
