Android Studio - Navigation between activities -

i may doing dumb mistake somewhere, , question may seem silly, but, can't figure out reason why happening.

i have homeactivity imageview , when click on it, need go dummyactivity(created purpose of testing). dummyactivity has textview text, "this dummy page". but, screen doesn't display anything.

i newbie android studio, but, guess doesn't relate it.

here code:

imageview onclick in homeactivity:

 mimageview1 = (imageview) findviewbyid(r.id.imageview_1);  mimageview1.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {              log.d("homeactivity", "imageview 1 clicked");             //startactivity(new intent(homeactivity.this, mainactivity.class));             startactivity(new intent(homeactivity.this, dummyactivity.class));         }     }); 

dummyactivity oncreate():

public class dummyactivity extends appcompatactivity{  @override public void oncreate(bundle savedinstancestate, persistablebundle persistentstate) {     super.oncreate(savedinstancestate, persistentstate);     setcontentview(r.layout.activity_dummy); } } 

activity_dummy.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"     android:orientation="vertical">      <textview         android:id="@+id/textview"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="this dummy page"         android:textappearance="?android:attr/textappearancelarge" />    </linearlayout> 

androidmanifest.xml

 <activity         android:name=".dummyactivity"         android:label="dummyactivity"></activity> 

the logcat displays, "imageview 1 clicked", nothing after that. no errors, nothing. doing wrong here?

update: changed backgroundcolor linearlayout , textcolor textview, changes not reflecting. preview in android studio showing layout fine, but, screen on device blank before, black background.

not sure why?

you have overriden wrong oncreate() method. use 1 instead:

public class dummyactivity extends appcompatactivity{     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate, persistentstate);         setcontentview(r.layout.activity_dummy);     } }
