【问题描述】:
已解决: 好的,所以我基本上是愚蠢的。我无法打开文件,因为我忘记安装 winrar 或 7zip,因为这台电脑是新格式化的……一切正常。很抱歉浪费了大家的时间。
在我的应用程序中,我以编程方式从目录中的照片和 .csv 文件生成 .zip 文件。
它会创建 zip,然后发送带有附件的电子邮件,而无需打断。然而问题是,在我的电脑上我无法提取 .zip 文件,因为它说它无效,但在我的设备上使用“WinZip”我可以检查我的 .zip 文件,它拥有它应该拥有的一切。这让我很困惑。
这是我的代码: 在这里我检查哪些复选框已被选中,然后进行压缩
for(int i = 0; i < cbStates.size(); ++i)
{
if(cbStates.get(i))
{
String zipFile = Environment.getExternalStorageDirectory() + "/ArcFlash/" + listItems.get(i) + ".zip";//ex: /storage/sdcard0/ArcFlash/study12.zip
String srcDir = Environment.getExternalStorageDirectory() + "/ArcFlash/" + listItems.get(i);
try
{
FileOutputStream fos = new FileOutputStream(zipFile);
ZipOutputStream zos = new ZipOutputStream(fos);
File srcFile = new File(srcDir);
Log.i("customException", "going to compress");
addDirToArchive(zos, srcFile);
// close the ZipOutputStream
zos.close();
}
catch (IOException ioe)
{
System.out.println("Error creating zip file: " + ioe);
}
//Send the email
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("application/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"jbasson@powercoreeng.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App");
String folderPath = Environment.getExternalStorageDirectory() + "/ArcFlash/" + listItems.get(i) + ".zip";
//Uri u = Uri.fromFile(folderPath);
//Log.i("customException", "uri path: " + u.getPath());
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + folderPath));
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
Toast.makeText(context,"Case \"" + studyName + "\" has been sent", Toast.LENGTH_LONG).show();
//adapter.setElement(i, adapter.getStudy(i) + "(sent)");
}
}
这里是 zip 函数:
private static void addDirToArchive(ZipOutputStream zos, File srcFile)
{
File[] files = srcFile.listFiles();
Log.i("customException", "Adding directory: " + srcFile.getName());
for (int i = 0; i < files.length; i++)
{
// if the file is directory, use recursion
if (files[i].isDirectory())
{
addDirToArchive(zos, files[i]);
continue;
}
try
{
System.out.println("tAdding file: " + files[i].getName());
// create byte buffer
byte[] buffer = new byte[2048];//1024
FileInputStream fis = new FileInputStream(files[i]);
zos.putNextEntry(new ZipEntry(files[i].getAbsolutePath() + "/" + files[i].getName()));//files[i].getName()
int length;
while ((length = fis.read(buffer)) > 0)
{
zos.write(buffer, 0, length);
}
zos.closeEntry();
// close the InputStream
fis.close();
}
catch (Exception ex)
{
Log.i("customException", "error zipping: " + ex.getMessage());
}
}
}
