好的,有一段时间我一直在从数据库中获取“名称”和“位置”并将它们列在一个表中。一个接一个地使用循环,直到全部显示,总共有 22 个。
例如。
name 1 | location 1
name 2 | location 2
name 3 | location 3
我想要的是不加载背景中的信息,因为我已经是,但只在需要时选择数据,所以我可以有图片 txt 然后是数据。
例如。
{Picture} {Picture}
{txt}{name 1} {txt}{name 2}
而不是将所有内容一个接一个地列出以使页面看起来更智能。顺便说一句,这是我的一级方程式应用程序的结果页面。
GetDataFromDB2.java ------
package com.test.test;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;
public class GetDataFromDB2 {
public String getDataFromDB() {
try {
HttpPost httppost;
HttpClient httpclient;
httpclient = new DefaultHttpClient();
httppost = new HttpPost(
"http://192.168.1.69/GetResults.php"); // change this to your URL.....
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpclient.execute(httppost,
responseHandler);
return response.trim();
} catch (Exception e) {
System.out.println("ERROR : " + e.getMessage());
return "error";
}
}
}
这是显示的Results.java

如果你能弄明白,你会看到它创建了自己的表格并进行了布局。我想要的只是在页面中的某些时间使用数据。ps 每个数据库条目作为它们的“id”例如
ID - 1. name 1. location 1. id - 2. name 2. locations 2 the id is just 1 - 22 would it be easyer using the id ?
