Android读取中文文件乱码解决方法

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 ;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(https://www.360docs.net/doc/1f12089979.html,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-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

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;

}

/**

* 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;

}
