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。
