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。
