当重点放在edittext键盘上时，警报对话框gettin崩溃

Question

AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
        LayoutInflater inflater = this.getLayoutInflater();
        View dialogView = inflater.inflate(R.layout.email_pop_layout, null);
        builder.setView(dialogView);
        AlertDialog alertDialog = builder.create();
        alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
        txt_student_password_layout = dialogView.findViewById(R.id.student_password_layout);
        txt_student_confirmpassword_layout = dialogView.findViewById(R.id.student_confirmpassword_layout);
        txt_student_confirm_password = dialogView.findViewById(R.id.student_confirm_password);
        txt_student_password = dialogView.findViewById(R.id.student_password);
        Button btn_savepassword = dialogView.findViewById(R.id.btn_savepassword);
        btn_savepassword.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showPasswordError();
                if (txt_student_password_layout.getError() == null && txt_student_confirmpassword_layout.getError() == null) {
                    alertDialog.dismiss();
                    hideKeyboardFrom(mContext, txt_student_confirmpassword_layout);
                    String password = encrypt("tuT0r$p@CehshAeS", "$p@CeTut0R004aEs", txt_student_confirm_password.getText().toString());
                    mCallback.changePassword(password.trim());
                } else {
                    showPasswordError();
                }
            }
        });
        //alertDialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
        alertDialog.show();


    }

当专注于edittext和虚拟键盘打开，然后应用崩溃时
