最近在做个MP3播放器，出现中文乱码问题，在网上找了很多解决办法，我整理了出现乱码的点和解决方案，拿出来和大家共享一下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 TextV iew textview ;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(yout.main);textview = (TextView) findView ById(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) {//转变编码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-8reader = 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 blocke.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（Tomcat6.0\conf\server.xml）。

设置编码为UTF-8<Connector port="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 blocke.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 exceptione.printStackTrace();return -1;} finally {try {inputStream.close();} catch (Exception e2) {e2.printStackTrace();}}return 0;}/*** 根据URL得到输入流** @param urlStr* @return* @throws MalformedURLException* @throws IOException*/public InputStream getInputStreamFromUrl(String urlStr)throws MalformedURLException, IOException {url = new URL(urlStr);HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();InputStream inputStream = urlConn.getInputStream();return inputStream;}。
