歌曲名、藝術家名顯示亂碼

MediaPickerActivity.java中新增方法changeStringEncode用來轉換字串編碼：

publicstatic String changeStringEncode(String content)

{

 if(java.nio.charset.Charset.forName("GB2312").newEncoder().canEncode(content))

  {

       //Log.d(TAG, "GB2312...");

  }

  elseif(java.nio.charset.Charset.forName("ISO-8859-1").newEncoder().canEncode(content))

  {

       //Log.d(TAG, "ISO-8859-1...");

      try

       {

                 content= new String(content.getBytes("ISO-8859-1"), "GBK");

       }

       catch (UnsupportedEncodingException e)

       {

                 //TODO Auto-generated catch block

                 e.printStackTrace();

        }

   }

   else if(java.nio.charset.Charset.forName("GBK").newEncoder().canEncode(content))

   {

        //Log.d(TAG, "GBK...");

   }

   elseif(java.nio.charset.Charset.forName("UTF-8").newEncoder().canEncode(content))

   {

                   try {

                 content= new String(content.getBytes("UTF-8"), "GBK");

        }

        catch (UnsupportedEncodingException e){

                 //TODO Auto-generated catch block

                 e.printStackTrace();

        }

                 //Log.d(TAG,"UTF-8...");

    }

    else if(java.nio.charset.Charset.forName("UTF-16").newEncoder().canEncode(content))

    {

        //Log.d(TAG, "UTF-16...");

    }

    return content;

}

之後在bindView中修改轉換標題名，專輯名，藝術家名：

//String name =cursor.getString(mTitleIdx);

String name =changeStringEncode(cursor.getString(mTitleIdx));

//name =cursor.getString(mAlbumIdx);

name = changeStringEncode(cursor.getString(mAlbumIdx));

//name =cursor.getString(mArtistIdx);

name = changeStringEncode(cursor.getString(mArtistIdx));

二、歌詞在切換語言後顯示亂碼

多語言環境中，中文歌曲的歌詞在中文環境下是正常顯示的，而切換到其他如法語、阿拉伯語等語言時，會發生亂碼的情況，修改點如下：

將

fileReader= new BufferedReader(new InputStreamReader(connection.getInputStream(),LyricsLocale.defLocale2CharSet()));

改為

FileInputStreamfis = new FileInputStream(lrcFile);

BufferedInputStreamin = new BufferedInputStream(fis);

in.mark(4);

byte[]first3bytes = new byte[3];

n.read(first3bytes);

in.reset();

if(first3bytes[0] == (byte) 0xEF && first3bytes[1] == (byte) 0xBB&& first3bytes[2] == (byte) 0xBF) {// utf-8

         fileReader = new BufferedReader(newInputStreamReader(new FileInputStream(lrcFile), "utf-8"));

}

elseif (first3bytes[0] == (byte) 0xFF && first3bytes[1] == (byte) 0xFE) {//unicode

         fileReader = new BufferedReader(newInputStreamReader(new FileInputStream(lrcFile), "unicode"));                                  

}

elseif (first3bytes[0] == (byte) 0xFE && first3bytes[1] == (byte) 0xFF) {//utf-16be

         fileReader = new BufferedReader(newInputStreamReader(new FileInputStream(lrcFile), "utf-16be"));                                                                      

}

elseif (first3bytes[0] == (byte) 0xFF && first3bytes[1] == (byte) 0xFF) {//utf-16le

         fileReader = new BufferedReader(newInputStreamReader(new FileInputStream(lrcFile), "utf-16le"));                                                                       

}

else{// GBK

         fileReader = new BufferedReader(newInputStreamReader(new FileInputStream(lrcFile), "GBK"));

}
