            <form [formGroup]="loginForm">
                <ion-item no-padding class="firstItem">
                    <ion-input [(ngModel)]="username" formControlName="username" type="email" spellcheck="false" autocapitalize="off">
                    </ion-input>
                </ion-item>
                <ion-item no-padding class="borderlineremove">
                    <ion-input [(ngModel)]="password" formControlName="password" clearOnEdit="false" type="password" spellcheck="false" autocapitalize="off">
                    </ion-input>
                </ion-item>
                <button class="loginForm" ion-button (click)="validateUser()" full color="danger">
                  <b>Sign In</b>
                </button>
                <ion-row>
                    <div class="forgotPwd"><span (click)="forGotPwd()">Forgot Password?</span></div>
                    <div class="signUp"><span (click)="registration()">Sign Up</span></div>
                </ion-row>
            </form>
        </ion-list>
    </div>

问题:

当我专注于键盘时,我无法移动键盘上方的表格,直到给出一些输入,但在android中一切正常.
