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");
			
			
		}
	});
    }
}
