1. AndroidManifest.xml加入权限：

permission android:name="android.permission.INTERNET" />

permission android:name="android.permission.ACCESS_NETWORK_STATE" />

2. android3.0以上凡是涉及到网络，下载等耗时操作，都不能在主线程中运行，不允许直接在ui线程直接操作httpClient

所以方法一：另起线程去访问。

方法二：如果不想另起线程，加上以下代码，可以取消严格限制

StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

3.获取网页内容代码：

代码一：

package List.com.list;
 
import org.apache.http.HttpResponse;
 
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.json.JSONArray;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
 
public class ListActivity extends Activity {
/** Called when the Activity is first created. */
 
public Button b = null;
public String s=null;
 
public ListView listview1=null;
 
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
 
b = (Button) findViewById(R.id.button1);
 
listview1=(ListView) findViewById(R.id.listview1);
 
b.setOnClickListener(new OnClickListener() {
 
public void onClick(View v) {
// TODO Auto-generated method stub
 
HttpGet httpget = new HttpGet("http://192.168.0.110:80/json/index.php");
HttpResponse httpresponse;
try {
 
//执行gethttp提交
httpresponse = new DefaultHttpClient().execute(httpget);
 
if(httpresponse.getStatusLine().getStatusCode()==200){
//如果成功吧返回的数据转换成string类型
String s=EntityUtils.toString(httpresponse.getEntity());
 
Log.i("JSON",s);
 
//声明一个json数组
JSONArray js JSONArray(s);
 
//声明一个数据组，长度他json数组的长度一样
String[] data=new String[jsonarray.length()];
 
//循环输出
for(int i=0;i arrayadapter=new ArrayAdapter(ListActivity.this, android.R.layout.simple_expandable_list_item_1,data);
//设置listview数据；
listview1.setAdapter(arrayadapter);
 
}
 
} catch (Exception e) {
Log.i("E",e.getMessage().toString());
 
}
 
}
});
 
 
 
}
}

代码二：

new Thread(){
public void run(){
client = new DefaultHttpClient(); 
StringBuilder builder = new StringBuilder(); 
HttpGet myget = new HttpGet("http://10.0.2.2/testAndroid.php"); 
//HttpGet myget = new HttpGet("http://www.crazyit.org"); 
try { 
HttpResponse response = client.execute(myget); 
HttpEntity entity = response.getEntity();
BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent())); 
for (String s = reader.readLine(); s != null; s = reader.readLine()) { 
builder.append(s); 
} 
JSONObject jsonObject = new JSONObject(builder.toString()); 
String re_password = jsonObject.getString("password"); 
 
} catch (Exception e) { 
e.printStackTrace(); 
} 
}
}.start();

代码三

void getInput(){   
try  
{  
URL url = new URL("http://www.google.cn/");  
HttpURLConnection conn = (HttpURLConnection) url.openConnection();  
conn.setDoInput(true);  
conn.setConnectTimeout(10000);  
conn.setRequestMethod("GET");  
conn.setRequestProperty("accept", "*/*");  
String location = conn.getRequestProperty("location");  
int resCode = conn.getResponseCode();  
conn.connect();  
InputStream stream = conn.getInputStream();  
byte[] data=new byte[102400];  
int length=stream.read(data);  
String str=new String(data,0,length);   
conn.disconnect();  
System.out.println(str);  
stream.close();  
}  
catch(Exception ee)  
{  
System.out.print("ee:"+ee.getMessage());   
}  
}
