1:建立activity_main.xml，代码如下：

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".MainActivity" >

android:id="@+id/etWord"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentLeft="true"

android:layout_alignParentTop="true"

android:layout_marginTop="27dp"

android:background="@android:drawable/edit_text"

android:ems="10"

android:singleLine="true"

android:textColor="#552006"

android:textColorHint="#782f10" >

android:id="@+id/wvSearchResult"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_alignLeft="@+id/etWord"

android:layout_below="@+id/etWord"

android:layout_marginTop="22dp"

android:textAppearance="?android:attr/textAppearanceMedium"

android:textSize="25sp" />

android:id="@+id/btnSearch"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignBaseline="@+id/etWord"

android:layout_alignBottom="@+id/etWord"

android:layout_toRightOf="@+id/etWord"

android:text="查询"

android:onClick="search" />

2:JAVA类：

package com.hnz.youdaodectionary;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.View;

import android.webkit.WebView;

import android.widget.EditText;

import android.widget.Toast;

public class MainActivity extends Activity {

private EditText etWord;

private WebView wvSearchResult;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

etWord = (EditText) findViewById(R.id.etWord);

wvSearchResult = (WebView) findViewById(R.id.wvSearchResult);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

public void search(View view){

String strURI = (etWord.getText().toString());

strURI = strURI.trim();

//如果查询内容为空提示

if (strURI.length() == 0)

{

Toast.makeText(MainActivity.this, "查询内容不能为空!", Toast.LENGTH_LONG)

.show();

}

//否则则以参数的形式从http://dict.youdao.com/m取得数据，加载到WebView里.

else

{

String strURL = "http://dict.youdao.com/m/search?keyfrom=dict.mindex&q="+ strURI;

wvSearchResult.loadUrl(strURL);

}
