Android編程實現將壓縮數據庫文件拷貝到安裝目錄的方法

本文實例講述了Android編程實現將壓縮數據庫文件拷貝到安裝目錄的方法。分享給大家供大家參考，具體如下：

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();
}

希望本文所述對大家Android程序設計有所幫助。
