本文实例讲述了Android编程实现将压缩数据库文件拷贝到安装目录的方法。分享给大家供大家参考，具体如下：

public void copyZip2DataDirectory(Context context) throws IOException {  FileOutputStream outputStream = null;  AssetManager assetManager = context.getAssets();  InputStream inputStream = assetManager.open("test.zip");  ZipInputStream zis = new ZipInputStream(inputStream);  ZipEntry entry = null;  while ((entry = zis.getNextEntry()) != null) {   outputStream = context.openFileOutput(entry.getName(), Context.MODE_PRIVATE);   byte[] buffer = new byte[2 * 1024];   int len = -1;   while ((len = zis.read(buffer)) != -1) {    outputStream.write(buffer, 0, len);   }   outputStream.close();  }  zis.close();  inputStream.close();}

希望本文所述对大家Android程序设计有所帮助。
