zip解压线程（解决中文问题）

准备工作：

android自带的zip解压不能处理中文文件名，需要引用第三方jar

apache的commons-compress 1.12

http://central.maven.org/maven2/org/apache/commons/commons-compress/1.12/commons-compress-1.12.jar

下载下来，放到app的libs目录

as转换到project视图

右击那个jar

然后：

就会在build.gradle(module:app)自动添加：

implementation files(‘libs/commons-compress-1.12.jar‘)

解压线程：

import android.app.ProgressDialog;
import android.content.Context;
import android.content.res.Resources;
import android.os.AsyncTask;
import android.support.annotation.NonNull;
import android.support.annotation.RawRes;
import android.util.Log;

import org.apache.commons.compress.archivers.ArchiveEntry;
import org.apache.commons.compress.archivers.zip.ZipArchiveInputStream;

import java.io.BufferedOutputStream;
import java.io.File;

import java.io.InputStream;
import java.io.OutputStream;
import java.io.UnsupportedEncodingException;

       //sdcard/download目录下zip  内含中文目录
//        LeesUnzipThread unzipThread=new LeesUnzipThread("/storage/emulated/0/download/dlsw.zip",mRoundProgressBar);
        int nFileCount=unzipThread.getFileCount();
        if(nFileCount>0){
            mRoundProgressBar.setMax(nFileCount);            //开始解压到目标文件夹
            unzipThread.execute("/storage/emulated/0/dlshouwen/");
