Moving from One activity to next in Android

i have two classes, how do I switch from one page to another page?

---

Both classes have to extend Activity, and be defined in the AndroidManifest.xml

To start Class2 from Class1 do this:

Intent i = new Intent(Class1.this, Class2.class);
startActivity(i);

AndroidManifest.xml:

<activity android:name="Class1"
                  android:label="Class1">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>
<activity android:name="Class2" android:label="Class2"></activity>

You can do this with the help of Intents. Just use the following code in one of the page

Intent i=new Intent("completepagename");
startActivity(i); 

where the page name A is like packagename.A

One page into other page in the sense..Is it another activity? In case of another activity u need to call that activity using intent only..

Intent intent = new Intent(); intent.setClass(firstclass.this,SecondClass.class); startActivity(intent);

Also go through this link.. start a new activity

Hope it will help you

you have to defined the activity in manifest file and both class have extend the class Intent i = new Intent(); i.setAction(android.intent.action.NEW_ACTIVITY); startActivity(i);

In Android Manifest.xml

<activity android:name="Baseclass" android:label="BaseClass"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="NewActivity" android:label="NewActivty"> <intent-filter> <action android:name="android.intent.action.NEW_ACTIVITY" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity>
