1.布局文件activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/ic_launcher"    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" >    <EditText        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" >        <requestFocus />    </EditText>    <WebView        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:background="@drawable/bg_roundcorner"        android:textAppearance="?android:attr/textAppearanceMedium"        android:textSize="25sp" />    <Button        android:id="@+id/btnSearch"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_above="@+id/wvSearchResult"        android:layout_alignParentRight="true"        android:background="@drawable/ibsearchword"        android:onClick="searchWord" /></RelativeLayout>

2.java代码

package com.nml.yd;import android.app.Activity;import android.os.Bundle;import android.text.TextUtils;import android.view.View;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {private EditText etWord;private WebView wvResult;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initViews();}private void initViews() {etWord = (EditText) findViewById(R.id.etWord);wvResult = (WebView) findViewById(R.id.wvSearchResult);wvResult.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url);return true;}});}public void searchWord(View view) {String word = etWord.getText().toString();if (TextUtils.isEmpty(word)) {Toast.makeText(this, "不能为空哦!", Toast.LENGTH_LONG).show();} else {final String strUrl = "http://dict.youdao.com/m/search?keyfrom=dict.mindex&vendor=&q="+ word;wvResult.loadUrl(strUrl);}}}

3.最后在配置文件AndroidMainfest.xml加入访问网络权限
<uses-permission android:name="android.permission.INTERNET"/>
