"errorCode":0

]

},

"web":[ // 有道词典-网络释义

}

下面实现android客户端功能。

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/a">
<EditText
android:id="@+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="输入你要查询的内容......" />
<Button
android:id="@+id/search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="查询" />
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="none" >
<TextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#000000"/>
</ScrollView>
</LinearLayout>

实现效果如下：
