package hind.jai.com.jaihind;  import android.app.actionbar; import android.app.fragment; import android.content.intent; import android.os.bundle; import android.support.v4.app.fragmentactivity; import android.support.v4.app.fragmenttabhost; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.button; import android.widget.imagebutton; import android.widget.imageview;  /**  * created sukhvir on 17/04/2015.  */ public class extends android.support.v4.app.fragment {     imagebutton img;      public view oncreateview(layoutinflater inflater,                              viewgroup container, bundle savedinstancestate) {           return inflater.inflate(                 r.layout.about, container, false);       }      @override     public void onactivitycreated( bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);          //get button view         img = (imagebutton) getview().findviewbyid(r.id.imagebutton);         //set onclick listener when button gets clicked         img.setonclicklistener(new view.onclicklistener() {             //start new list activity             public void onclick(view v) {                 intent mainintent = new intent(getactivity(), abcd.class);              }         });       }  }

about.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/about"     android:id="@+id/textview"     android:layout_gravity="center_horizontal" />      <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton"         android:background="@drawable/image2"         android:onclick="onclick"         android:layout_gravity="center_horizontal" />   </linearlayout>

and mentioned trying start new activity "abcd".

abcd.java

package hind.jai.com.jaihind;  import android.app.activity; import android.os.bundle;  /**  * created rishik on 14-06-2015.  */ public class abcd extends activity {     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.abcd);     } }

abcd.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent" android:layout_height="match_parent">      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="new text"         android:id="@+id/textview9"         android:layout_gravity="center_vertical" /> </linearlayout>
