　　1.读取中文文件乱码解决方法

 

package com.apj.conv;   

   

import java.io.BufferedInputStream;   

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 android.app.Activity;   

import android.os.Bundle;   

import android.os.Environment;   

import android.widget.TextView;   

   

public class ConverActivity extends Activity {   

        

    private TextView textview ;   

        

        

    @Override  

    public void onCreate(Bundle savedInstanceState) {   

        super.onCreate(savedInstanceState);   

        setContentView(R.layout.main);   

            

        textview = (TextView) findViewById(R.id.lrctext);   

            

          

        System.out.println("===================convertCodeAndGetText begin=================== ");   

        ///获得SDCard中文件的路径   

        String path = Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator ;   

        String tochinese = convertCodeAndGetText(path+"a.txt");   

        System.out.println(tochinese);   

        System.out.println("===================cconvertCodeAndGetText end===================");   

        textview.setText(tochinese);   

            

    }   

       

    public String convertCodeAndGetText(String str_filepath) {// ת��   

   

        File file = new File(str_filepath);   

        BufferedReader reader;   

        String text = "";   

        try {   

                

            FileInputStream fis = new FileInputStream(file);   

            BufferedInputStream in = new BufferedInputStream(fis);   

            in.mark(4);   

            byte[] first3bytes = new byte[3];   

            in.read(first3bytes);   

            in.reset();   

            if (first3bytes[0] == (byte) 0xEF && first3bytes[1] == (byte) 0xBB  

                    && first3bytes[2] == (byte) 0xBF) {// utf-8   

   

                reader = new BufferedReader(new InputStreamReader(in, "utf-8"));   

   

            } else if (first3bytes[0] == (byte) 0xFF  

                    && first3bytes[1] == (byte) 0xFE) {   

   

                reader = new BufferedReader(   

                        new InputStreamReader(in, "unicode"));   

            } else if (first3bytes[0] == (byte) 0xFE  

                    && first3bytes[1] == (byte) 0xFF) {   

   

                reader = new BufferedReader(new InputStreamReader(in,   

                        "utf-16be"));   

            } else if (first3bytes[0] == (byte) 0xFF  

                    && first3bytes[1] == (byte) 0xFF) {   

   

                reader = new BufferedReader(new InputStreamReader(in,   

                        "utf-16le"));   

            } else {   

   

                reader = new BufferedReader(new InputStreamReader(in, "GBK"));   

            }   

            String str = reader.readLine();   

   

            while (str != null) {   

                text = text + str + "\n";   

                str = reader.readLine();   

   

            }   

            reader.close();   

   

        } catch (FileNotFoundException e) {   

            // TODO Auto-generated catch block   

            e.printStackTrace();   

        } catch (IOException e) {   

            e.printStackTrace();   

        }   

        return text;   

    }   

   

}  

2. 连接网络读取文件内容中文乱码解决办法

URL myFileUrl = null;      

   myFileUrl = new URL(url);   

   HttpURLConnection conn;   

   conn = (HttpURLConnection) myFileUrl.openConnection();   

   conn.setDoInput(true);   

   conn.connect();   

   InputStream is = conn.getInputStream();   

   BufferedReader br = new BufferedReader(new InputStreamReader(is,   

     "GB2312"));   

   sb = new StringBuffer();   

   String data = "";   

   while ((data = br.readLine()) != null) {      

        sb.append(data+"\n");      

   }      

   String result = sb.toString();  

3.读取网络文件中文名下载乱码解决办法
　　1).先在设置服务器编码：找到Tomcat安装目录下的server.xml文件（Tomcat 6.0\conf\server.xml）。设置编码为UTF-8
　　<Connectorport="8080" URIEncoding="UTF-8" redirectPort="8443" connectionTimeout="20000" protocol="HTTP/1.1"/>
　　2). android 中代码为：

try {   

         lrcUrl = "http://192.168.0.214/vote/mp3/" + URLEncoder.encode("中文.mp3","UTF-8");   

        } catch (UnsupportedEncodingException e) {   

            // TODO Auto-generated catch block   

            e.printStackTrace();   

        }   

   

        int result1 = downFile(lrcUrl, "mp3/", "中文.mp3");   

**   

 * 该函数返回整型( -1：代表下载文件出错 ；0：代表下载成功；1：代表文件已存在)   

 **/   

public int downFile(String urlStr, String path, String fileName) {   

    InputStream inputStream = null;   

    try {   

        FileUtils fileUtils = new FileUtils();   

        if (fileUtils.isFileExist( fileName,path )) {   

            return 1;   

        } else {   

            inputStream = getInputStreamFromUrl(urlStr);   

            File resultFile = fileUtils.write2SDFromInput(path, fileName,   

                    inputStream);   

            if (resultFile == null) {   

                return -1;   

            }   

   

        }   

    } catch (Exception e) {   

        // TODO: handle exception   

        e.printStackTrace();   

        return -1;   

    } finally {   

        try {   

            inputStream.close();   

        } catch (Exception e2) {   

            e2.printStackTrace();   

        }   

    }   

    return 0;   

}

public InputStream getInputStreamFromUrl(String urlStr)   

        throws MalformedURLException, IOException {
