1. AndroidManifest.xml加入許可權:
permission android:name="android.
permission.INTERNET" />
permission android:name="android.permission.ACCESS_NETWORK_STATE" />
2. android3.0以上凡是涉及到網路,下載等耗時操作,都不能在主線程中運行,不允許直接在ui線程直接操作httpClient
所以方法一:另起線程去訪問。
方法二:如果不想另起線程,加上以下代碼,可以取消嚴格限制
StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
3.擷取網頁內容代碼:
代碼一:
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 { //執行gethttp提交httpresponse = new DefaultHttpClient().execute(httpget); if(httpresponse.getStatusLine().getStatusCode()==200){//如果成功吧返回的資料轉換成string類型String s=EntityUtils.toString(httpresponse.getEntity()); Log.i("JSON",s); //聲明一個json數組JSONArray js JSONArray(s); //聲明一個資料群組,長度他json數組的長度一樣String[] data=new String[jsonarray.length()]; //迴圈輸出for(int i=0;i arrayadapter=new ArrayAdapter(ListActivity.this, android.R.layout.simple_expandable_list_item_1,data);//設定listview資料;listview1.setAdapter(arrayadapter); } } catch (Exception e) {Log.i("E",e.getMessage().toString()); } }}); }}
代碼二:
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();
代碼三
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()); } }
以上就介紹了android 擷取php網頁內容,包括了方面的內容,希望對PHP教程有興趣的朋友有所協助。
