安卓开发文件和文件压缩成zip文件

private static void toZip(String srcFileString, String zipFileString){
        FileOutputStream fos1=null;
        ZipOutputStream zip=null;
        try{
             fos1 = new FileOutputStream(new File(zipFileString));
             zip= new ZipOutputStream(fos1);
            File f = new File(srcFileString);
            compress(f, zip, f.getName());
            zip.flush();
            zip.close();
            fos1.close();
        } catch (Exception e) {
            try {
                if(zip!=null)zip.close();
                if(fos1!=null)fos1.close();
            } catch (IOException ee) {}
            
        }
    }
    private static void compress(File sourceFile, ZipOutputStream zos, String name) throws Exception {
        int  BUFFER_SIZE = 2 * 1024;
        byte[] buf = new byte[BUFFER_SIZE];
        if (sourceFile.isFile()) {
            // 向zip输出流中添加一个zip实体，构造器中name为zip实体的文件的名字
            zos.putNextEntry(new ZipEntry(name));
            // copy文件到zip输出流中
            int len;
            FileInputStream in = new FileInputStream(sourceFile);
            while ((len = in.read(buf)) != -1) {
                zos.write(buf, 0, len);
            }
            // Complete the entry
            zos.closeEntry();
            in.close();
        } else {
            File[] listFiles = sourceFile.listFiles();
            if (listFiles == null || listFiles.length == 0) {
                    // 空文件夹的处理
                    zos.putNextEntry(new ZipEntry(name + "/"));
                    // 没有文件，不需要文件的copy
                    zos.closeEntry();

            } else {
                for (File file : listFiles) {
                        compress(file, zos, name + "/" + file.getName());
                }
            }
        }
        }

使用方法

public static void main(String[] args) 
    {
        
        toZip("/sdcard/temp","/sdcard/myzip.zip");
        System.out.println("ok");

    }
