Android: Close the virtual "on-screen" keyboard

There was a slight quirk that I ran into while working on my app. If I were editing text and clicked "Save" on the activity, it'd close the screen but keep the keyboard open.

I'd then have to press the BACK button to close it. A small but somewhat irritating quirk. Luckily, its an easy thing to fix.

First, define an "OnFocusChangeListener":

view sourceprint?

01.private OnFocusChangeListener hideKeyboard = new OnFocusChangeListener() {

02.  @Override

03.  public void onFocusChange(View v, boolean hasFocus) {

04.    if (!hasFocus) {

05.      InputMethodManager imm = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);

06.      imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

07.    }

08.  }

09.};

When you're creating and setting up your edit boxes, just set the following listeners:

view sourceprint?

1.txtEmail.setOnFocusChangeListener(hideKeyboard);

2.txtUsername.setOnFocusChangeListener(hideKeyboard);

There you have it. It should now hide the keyboard automatically.

If no other objects take focus, then just call the listener manually.

view sourceprint?

1.hideKeyboard.onFocusChange(txtUsername, false);

2.hideKeyboard.onFocusChange(txtEmail, false);
