android使用Intent来实现页面跳转，接下来通过本文给大家分享Android 实现页面跳转的实例代码，需要的的朋友参考下吧
android使用Intent来实现页面跳转，Intent通过startActivity(Intent intent)或startActivityForResult(Intent intent,int resquestCode)方法来启动Activity，在新建Intent对象时来指定从A页面跳到B页面，
比如：
Intent i = new Intent(A.this,B.class);这就表示从A页面跳到B页面，
Intent对象通过调用putExtra方法来传递页面跳转时所需要传递的信息
比如：
putExtra（“给需要传递的信息命名”，需要传递的信息的内容）
Intent通过调用getStringExtra方法来接受传递过来的信息
getStringExtra（“传递过来的信息的名字”）；
下面的代码将实现用户输入完信息之后点击登入按钮，页面将跳转到另一页面显示个人信息，然后在这个页面有一个返回按钮，点击返回按钮，页面将返回登入页面再次显示个人信息。
