首先，我是新手，我已经按照教程使用 Yii 框架作为服务器创建网站。一个带有 CRUD 功能的简单网站已经构建完成。现在我想将它与我的 android 应用程序连接起来。

我的平台：Win 7 64、Eclipse IDE、Android ADT、GenyMotion。

/* Yii 侧 */

这是我在 (protected\controllers\EmployeeController.php) 上的 EmployeeController

public function actionGetEmployee($id)
{
    header('Content-type: application/json');
    $employee = Employee::model()->findAll();
    echo CJSON::encode($employee);
    Yii::app()->end();
}

上面代码的结果是这样的：

[
{
    "id": "1",
    "departmentId": "1",
    "firstName": "Hendy",
    "lastName": "Nugraha",
    "gender": "female",
    "birth_date": "1987-03-16",
    "marital_status": "Single",
    "phone": "856439112",
    "address": "Tiban Mutiara View ",
    "email": "hendy.nugraha87@yahoo.co.id",
    "ext": "1",
    "hireDate": "2012-06-30 00:00:00",
    "leaveDate": "0000-00-00 00:00:00"
},
{
    "id": "2",
    "departmentId": "2",
    "firstName": "Jay",
    "lastName": "Branham",
    "gender": "male",
    "birth_date": "0000-00-00",
    "marital_status": "Single",
    "phone": "0",
    "address": "",
    "email": "jaymbrnhm@labtech.org",
    "ext": "2",
    "hireDate": "0000-00-00 00:00:00",
    "leaveDate": "0000-00-00 00:00:00"
}
]

/* 现在在 Android 端 */

这是 main.xml ：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Edit" />

                <Button
                    android:id="@+id/btnhapus"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Hapus" />
            </TableRow>
        </TableLayout>
    </LinearLayout>

    <LinearLayout
        android:id="@+id/detail"
        android:layout_width="match_parent"

    </LinearLayout>
</LinearLayout>
 </ScrollView>

这是日志猫：

11-04 16:23:47.273: E/JSON Parser(1867): Error parsing data org.json.JSONException: Value <!DOCTYPE of type java.lang.String cannot be converted to JSONObject

我的问题是：当 android 应用程序运行时，我单击刷新按钮，它没有显示包含员工 json 数据的表格布局。任何帮助都会非常感激。谢谢。

我认为您在从 Android 应用程序发出请求时出错，因为<!DOCTYPE是网页的开始。尝试查看来自 Android 应用程序的请求结果。
