材质设计TextInputLayout PasswordToggle位置

Question

我使用材料设计来绘制我的密码输入框，如下所示，并带有passwordToggleEnabled，但是密码眼球图标太靠近右边框。我尝试使用paddingRight或layout_marginRight，它们都只是缩短了输入框，并且眼球图标仍然靠近笔触线。有什么建议吗？

    <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/text_input_layout_password"
            android:hint="Password"
            android:layout_marginTop="10dp"
            android:paddingLeft="10dp"
            android:textColorHint="@color/com_facebook_likeview_text_color"
            app:hintTextAppearance="@style/HintTextStyle"
            app:errorEnabled="true"
            app:errorTextAppearance="@style/error_appearance"
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
            app:boxStrokeColor="@color/white"
            app:boxCornerRadiusTopStart="20dp"
            app:boxCornerRadiusBottomEnd="20dp"
            app:boxCornerRadiusBottomStart="20dp"
            app:boxCornerRadiusTopEnd="20dp"
            app:boxStrokeWidth="1dp"
            android:outlineSpotShadowColor="@color/white"
            app:passwordToggleContentDescription="Show Password"
            app:passwordToggleDrawable="@drawable/ic_sign_up_screen_password_eyeball"
            app:passwordToggleTint="@color/white"
            app:passwordToggleEnabled="true"
            right
