當(dāng)dialog中包含EditeText的時(shí)候，假如當(dāng)前軟鍵盤是彈出的狀態(tài)，當(dāng)dialog執(zhí)行dismiss()的時(shí)候該軟鍵盤并不會(huì)消失。如果需要軟鍵盤隱藏，重寫dismiss()方法

  @Override
    public void dismiss() {
        View view = getCurrentFocus();
        if (view instanceof TextView) {
            InputMethodManager mInputMethodManager = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            mInputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.RESULT_UNCHANGED_SHOWN);
        }
        super.dismiss();
    }
