            }
        });
    }

Answer 1

there are two ways to handle this, the simplest way is use a non-size-edittext

don't hide the text view, if it hide then edtTxt.getText().toString() gets empty always

<EditText
    android:id="@+id/edtTxt"
    android:layout_width="0px"
    android:layout_height="0px" />

So that user can't see that. and on click of button

edtTxt.requestFocus();
edtTxt.setText("");
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

inputMethodManager.toggleSoftInputFromWindow(edtTxt.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED,
            0);

Now edtTxt.getText().toString() giving text.

Without an EditText you're going to have a hard time.

An InputMethod needs to be connected to a view. Whatever view you use, you need to override onCreateInputConnection to return a custom InputConnection object that at a minimum implements commitText (for word input), deleteSurroundingText (for deletes), and sendKeyEvent (for keyboards that assume you're in dumb mode), and all of the completion functions. Input connections are complicated things and you'll screw up 3rd party keyboards like Swiftkey and Swype if you don't get it right. I really don't suggest doing this.

If you want to do this your best chance of getting it right is to claim your window is a TYPE_NULL input type. Most keyboards will dumb themselves down and assume you only accept the simplest commands in that mode. But you can't count on it.

I'd look at the InputConnection returned by the EditText class and copy as much of it as possible.
