1. AndroidManifest.xml加入权限：

<uses-permission android:name="android.permission.INTERNET" />

<uses-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; @Overridepublic 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 jsonarray=new 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<jsonarray.length();i++){ Log.i("dd",jsonarray.getJSONObject(i).getString("ddd"));Log.i("tt",jsonarray.getJSONObject(i).getString("title")); //把结果存到一个数组里；data[i]=jsonarray.getJSONObject(i).getString("ddd")+jsonarray.getJSONObject(i).getString("title");}  ArrayAdapter<String> arrayadapter=new ArrayAdapter<String>(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());   }  }
