WebView的Demo

1.首先上布局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="wrap_content"    android:orientation="vertical" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="请输入网址：" />        <EditText        android:id="@+id/webaddress"        android:layout_width="fill_parent"        android:layout_height="wrap_content"         />  <LinearLayout     android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal" >      <Button        android:id="@+id/bt1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="下载资源"         />    <Button        android:id="@+id/bt2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"         android:text="下载数据"         />        </LinearLayout><WebView     android:id="@+id/webview"    android:layout_width="fill_parent"    android:layout_height="fill_parent"/></LinearLayout>

2.上一下所需的活动WebViewActivity.java

package com.wang;import android.R.string;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.webkit.WebView;import android.widget.Button;import android.widget.EditText;public class WebViewActivity extends Activity {    private WebView webview;private EditText webaddress;    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);            webview=(WebView)findViewById(R.id.webview);    Button button=(Button)findViewById(R.id.bt1);    button.setOnClickListener(new OnClickListener() {public void onClick(View v) {webaddress=(EditText)findViewById(R.id.webaddress);String path=webaddress.getText().toString();//在webView中输入网址，http开头webview.loadUrl(path);}});    Button button1=(Button)findViewById(R.id.bt2);    button1.setOnClickListener(new OnClickListener() {public void onClick(View v) {webaddress=(EditText)findViewById(R.id.webaddress);String data="<a href='http://www.baidu.com'>baidu</a>";webview.loadData(data, "text/html", "utf-8");}});    }}

3。亲，别忘了权限哦！<uses-permission  android:name="android.permission.INTERNET"/>
