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。
