1.定义一个实体类

用于解析srt文件的内容

public class SRT {

private int beginTime;

private int endTime;

private String srtBody;

public int getBeginTime() {

return beginTime;

}

public void setBeginTime(int beginTime) {

this.beginTime = beginTime;

}

public int getEndTime() {

return endTime;

}

public void setEndTime(int endTime) {

this.endTime = endTime;

}

public String getSrtBody() {

return srtBody;

}

public void setSrtBody(String srtBody) {

this.srtBody = srtBody;

}

@Override

public String toString() {

return "" + beginTime + ":" + endTime + ":" + srtBody;

}

}

2.定义一个方法解析srt文件，并存放在集合中

public class SrtParser {

public static int lastEndTime;

private static ArrayList enSrtList;

private static String content;

/**

* 解析SRT字幕文件

* 字幕路径

*/

public static void parseSrt(String name, ArrayList srtList) {

InputStream inputStream = null;

try {

inputStream = new FileInputStream(name);

BufferedReader br = new BufferedReader(new InputStreamReader(

inputStream, "UTF-8"));

String line = null;

StringBuffer sb = new StringBuffer();

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

if (!line.equals("")) {

sb.append(line).append("@");

continue;

}

String[] parseStrs = sb.toString().split("@");

// 该if为了适应一开始就有空行以及其他不符格式的空行情况

if (parseStrs.length < 3) {

sb.delete(0, sb.length());// 清空，否则影响下一个字幕元素的解析

continue;

}

SRT srt = new SRT();

// 解析开始和结束时间

String timeTotime = parseStrs[1];

int begin_hour = Integer.parseInt(timeTotime.substring(0, 2));

int begin_mintue = Integer.parseInt(timeTotime.substring(3, 5));

int begin_scend = Integer.parseInt(timeTotime.substring(6, 8));

int beginTime = (begin_hour * 3600 + begin_mintue * 60 + begin_scend)

* 1000;

int end_hour = Integer.parseInt(timeTotime.substring(14, 16));

int end_mintue = Integer.parseInt(timeTotime.substring(17, 19));

int end_scend = Integer.parseInt(timeTotime.substring(20, 22));

int endTime = (end_hour * 3600 + end_mintue * 60 + end_scend)

* 1000;

//解析字幕文字

String srtBody = "";

// 可能1句字幕，也可能2句及以上。

for (int i = 2; i < parseStrs.length; i++) {

srtBody += parseStrs[2] + "\n";

}

// 删除最后一个"\n"

srtBody = srtBody.substring(0, srtBody.length() - 1);

// 设置SRT

srt.setBeginTime(beginTime);

srt.setEndTime(endTime);

srt.setSrtBody(srtBody);

srtList.add(srt);

sb.delete(0, sb.length());// 清空，否则影响下一个字幕元素的解析

}

lastEndTime = srtList.get(srtList.size() - 1).getEndTime();

br.close();

} catch (IOException e) {

e.printStackTrace();

}

}

//显示字幕(双语显示，如果只是单语显示，不要 if (isGB2312(srtBody)) 这个判断)

public static void showSRT(GiraffePlayer videoView, TextView tvSrtCN, TextView tvSrtEN, String s, ArrayList srtList, int size) {

int currentPosition = videoView.getCurrentPosition();//vv是VideoView播放器

if (currentPosition > lastEndTime) {

tvSrtCN.setVisibility(View.GONE);

tvSrtEN.setVisibility(View.GONE);

}

for (int i = 0; i < srtList.size(); i++) {

SRT srtbean = srtList.get(i);

if (currentPosition >= srtbean.getBeginTime()

&& currentPosition <= srtbean.getEndTime()) {

String srtBody = srtbean.getSrtBody();

if (isGB2312(srtBody)) {

tvSrtCN.setVisibility(View.VISIBLE);

tvSrtCN.setText(srtBody);

Log.e("wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww", "中文");

} else {

tvSrtEN.setVisibility(View.VISIBLE);

tvSrtEN.setText(srtBody);

Log.e("wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww", "英文");

}

//显示过的就删掉，提高查询效率

// srtList.remove(i);

// break;//找到后就没必要继续遍历下去，节约资源

} else {

if (i < srtList.size() - 2 && currentPosition > srtbean.getEndTime() && currentPosition < srtList.get(i + 1).getBeginTime()) {

tvSrtCN.setVisibility(View.GONE);

tvSrtEN.setVisibility(View.GONE);

}

}

}

// }

}

public static Boolean isGB2312(String str) {

for (int i = 0; i < str.length(); i++) {

String bb = str.substring(i, i + 1);

// 生成一个Pattern,同时编译一个正则表达式,其中的u4E00("一"的unicode编码)-\u9FA5("龥"的unicode编码)

boolean cc = java.util.regex.Pattern.matches("[\u4E00-\u9FA5]", bb);

if (cc == false) {

return cc;

}

}

return true;

}

3.下载srt文件

根据服务器提供的地址，下载srt字幕文件，存储在本地，然后调用解析的方法，显示字幕，并且用Handler每个多少秒去遍历集合显示字幕

//下载的逻辑自己去处理

//本地存储的路径

String name = Environment.getExternalStorageDirectory().getPath() + "/" + srt;

//解析srt文件

SrtParser.parseSrt(name, srtList);

//发送Handler请求，每个5秒

mHandler.sendEmptyMessageDelayed(0, 500);

Handler mHandler = new Handler() {

public void handleMessage(Message msg) {

switch (msg.what) {

case PARSE_SRT_CN:

SrtParser.showSRT(mGiraffePlayer, cn_subtitleview, en_subtitleview, "cn", srtList, size);

//每隔500ms执行一次showSRT()

mHandler.sendEmptyMessageDelayed(0, 500);

}

}

};
