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。
