我已将数据转移到新活动 - ＆gt;从HotelListAdapter.java到HotelPage.java
我设置Log以确保数据已成功传输。 Log现在正在工作并显示我的变量值，但我的TextView和ImageView不显示我的数据（或变量）......
这是我的LogCat：
import { Component, Directive } from '@angular/core';
import {
FormControl,
Validators,
AbstractControl,
NG_VALIDATORS,
REACTIVE_FORM_DIRECTIVES
} from '@angular/forms';
function validateRegex(control: FormControl): {[key:string]: boolean} {
if (!control.value || !control.value.match(/^pee/)) {
return { 'badName': true };
}
}
@Directive({
selector: '[validateRegex]',
providers: [
{ provide: NG_VALIDATORS, useValue: validateRegex, multi: true }
]
})
export class RegexValidator {
}
@Component({
moduleId: module.id,

template: `
