Android 音乐乱码问题修改

标签：android   音乐 乱码   

对于Android音乐播放器的音乐人 ，专辑，音乐名字显示乱码的修改做了下总结：

方法一：在frameworks\base\media\java\android\media\MediaScanner.java中修改：函数handleStringTag

在这个函数中加上字符编码的转换；

<span style="font-family:KaiTi_GB2312;font-size:18px;">/*add by tanfusheng @20150110 start */
        private boolean isEncoding(String value,String code) throws UnsupportedEncodingException{
            return value.equals(new String(value.getBytes(code),code));
        }
         /*add by tanfusheng @20150110 end */
        public void handleStringTag(String name, String value) {
         /*add by tanfusheng @20150110  start */
            try{
                if(isEncoding(value,"ISO-8859-1")){
                    value = new String(value.getBytes("ISO-8859-1"),"GBK");
                }
            }catch(UnsupportedEncodingException e){
                e.printStackTrace();
            }
             /*add by tanfusheng @20150110  end */</span>

方法二：在frameworks\av\media\libmedia\MediaScannerClient.cpp中修改：

<span style="font-family:KaiTi_GB2312;font-size:18px;">void MediaScannerClient::endFile()
{
if (mLocaleEncoding != kEncodingNone) {
int size = mNames->size();
+ int count = 0;
uint32_t encoding = kEncodingAll;
uint32_t tmpEncoding = kEncodingAll;
uint32_t srcEncoding = kEncodingNone;

for (int i = 0; i < mNames->size(); i++) {
tmpEncoding = possibleEncodings(mValues->getEntry(i));
// If no multibyte encoding is detected or GBK is the only possible multibyte encoding, just ignore
- if( (kEncodingNone != tmpEncoding) && (kEncodingCP1252 != tmpEncoding)
- && ((kEncodingGBK | kEncodingCP1252) != tmpEncoding) ) {
- encoding &= tmpEncoding;
+ if( (kEncodingNone == tmpEncoding) || ((kEncodingGBK | kEncodingCP1252) == tmpEncoding) ) {
+ continue;
}
+
+ if( kEncodingCP1252 == tmpEncoding ) {
+ ++count;
+ continue;
+ }
+
+ encoding &= tmpEncoding;
LOGV("value: %s, tmpEncoding: %x\n", mValues->getEntry(i), tmpEncoding);
}
+
+ if(count >= 2) {
+ encoding = kEncodingAll;
+ }
LOGV("possibleEncodings: %x\n", encoding);
...
}</span>

希望遇到此乱码的问题可以用得上，如果这样改了还会乱码，那就是单首音乐的问题了，就得用千千静听去修改那首音乐的编码方式了，至于方法可以百度到的。
