切换viewpager时关闭键盘

　　EditText添加焦点监听事件，当该EditText失去焦点时，关闭键盘。

EditText editTextProfileName = (EditText) view
                    .findViewById(R.id.nameEditText);

            editTextProfileName.setOnFocusChangeListener(new OnFocusChangeListener() {

                public void onFocusChange(View v, boolean hasFocus) {
                      if (!hasFocus) {
                            hideKeyboard();
                        }
                }

                private void hideKeyboard() {
                    if (editTextProfileName != null) {
                        InputMethodManager imanager = (InputMethodManager) getActivity()
                                .getSystemService(Context.INPUT_METHOD_SERVICE);
                        imanager.hideSoftInputFromWindow(editTextProfileName.getWindowToken(), 0);

                    }

                }
            });
