On this page to try the page jump (just to a blank page first to get the jump code familiar), but slow to jump, jump code as follows:

After a few twists and turns for the following reasons: The new activity needs to be registered, otherwise the operation will be error, as shown in. Open a Androidmanifest.xml file, add <activity android:name= ". Mianactivity "></activity> code, simple registration is OK. Be sure to register, otherwise the jump will flash back!

Today the smooth completion of the page jump!
