病态使用这个code读它在我的应用程序:
Ill read it in my application using this code:
package au.edu.canberra.g30813706;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.Arrays;
import android.app.Activity;
import android.os.Environment;
public class FileReader extends Activity{{
ArrayList<String> sInfo = new ArrayList<String>();
String txtName = "AccomodationTxt.txt";
File root = Environment.getExternalStorageDirectory();
File path = new File(root, "CanberraTourism/" + txtName);
try {
BufferedReader br = new BufferedReader (
new InputStreamReader(
new FileInputStream(path)));
String line;
String[] saLineElements;
while ((line = br.readLine()) != null)
{
//The information is split into segments and stored into the array
saLineElements = line.split(";");
for (int i = 0; i < saLineElements.length; i++)
sInfo.add(saLineElements[i]);
//sInfo.addAll(Arrays.asList(saLineElements[0], saLineElements[1], saLineElements[3]));
}
br.close();
}
catch (FileNotFoundException e) {
System.err.println("FileNotFoundException: " + e.getMessage());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}}
}
我将如何区分线阵列?
How would i differentiate the lines in the Array?
例如
我要显示一个页面上的名称的文本,所以只有
I would want to display the text of the names on one page, so only

推荐答案
有关添加字符串数组到ArrayList,而不是单个元素是什么。结果
像这样的:
What about adding the String arrays to the ArrayList instead of the individual elements.
Like this:
ArrayList<String[]> sInfo = new ArrayList<String[]>();
String line;
String[] saLineElements;
while ((line = br.readLine()) != null)
{
//The information is split into segments and stored into the array
saLineElements = line.split(";");
sInfo.add(saLineElements);
}
然后,你可以遍历sInfo并使用第一个元素sInfo每个数组中的
Then you could loop through sInfo and use the first element in each array in sInfo.
