[Android] 拿到PHP Server的訊息

1. 在Manifest.xml裡插入

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

2.創建一個新的Activity，GetServer.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

package com.example.photothrow1; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.util.EntityUtils; public class GetServer {     public String stringQuery(String url){         try {             HttpClient httpClient = new DefaultHttpClient();             HttpPost httpPost = new HttpPost(url);             HttpResponse response = httpClient.execute(httpPost);             HttpEntity httpEntity = response.getEntity();             if (httpEntity!=null)                 return EntityUtils.toString(httpEntity);             else                 return "no string.";         } catch (Exception e) {             // TODO: handle exception             return "Network Problem.";         }     } }


3. 在MainActivity（也可以是別的）加入一個method，可以在OnCreat呼叫這個method就好



?

1 2 3 4 5

public void getServerMsg(){            GetServer server = new GetServer();            String msg = server.stringQuery("http://你的IP地址/test.php");            server_msg.setText(msg);    }


4. 在你的server新增php（ex test.php）

?

1 2 3

<?php     echo "Hi, I'm server."; ?>
