If i put the button before appbar it does not show up. If i put it inside, it shows up but it does not fit properly (height is under imageview and the two can not be in the same height). I tried different layouts other than coordinatorlayout and it hapens again there too.

It is not showing because you've used "#android:color/transparent" as background for your ImageButton. Chose another color and it will be visible. Or just add some text so that you can see it.
I have just started android studio, and I can't seem to see the "Hello World" text in my build:
When I switch to another theme I am able to see the text, what could be the problem?
Edit:
The color is not the same as the background.
layout xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

Thank you!
According to the information presented about the problem, you need the closing label of ConstraintLayout
</android.support.constraint.ConstraintLayout>
they stay like this
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:textColor="#color/colorAccent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.44" />
</android.support.constraint.ConstraintLayout>
Or you may need to restart the android studio cache
go to the menu file> restat caches / restart
I hope I've helped
I'm working on a project in Android Studio. I created a Navigation Drawer project, using 16 as my minSdkVersion. My Notification bar has a strange shadow (this is my AppBar) and I want to have material design's notification bar (this is Material Design's Appbar).
Default code is:

Good day can you help me correct this one?
In my activity_main.xml, I used Coordination Layout So that my Appbar will work.

And In my First Tab my - Organizations feeds don't work, it stuck and will not me allow to slide up to show up the feeds. But sometimes it will work sliding up but, there is an overlapping of layout. I just include my cardview_items.xml as an overview on how it looks like.

I really need your help. I'm stuck with this one.
Thank you in advance.
It should be fairly easy to fix:
Remove ViewPager from AppBarLayout
Add ViewPager as a sibling to a AppBarLayout and add for it app:layout_behavior="#string/appbar_scrolling_view_behavior" and set layout_width & layout_height to match_parent
So your layout should look like afterwards:
<android.support.design.widget.CoordinatorLayout
....>
<android.support.design.widget.AppBarLayout
.....>
<include
android:id="#+id/toolbar"
layout="#layout/tool_bar"/>
<android.support.design.widget.TabLayout
.../>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
.....
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
I hope, it helps.
