Toolbar and TabLayout is not visible on Android 4.4 devices

Question

I was trying to implement Toolbar and TabLayout using google design library by referring to [http://blog.grafixartist.com/material-design-tabs-with-android-design-support-library/] [blog].

Output works as expected on Lollipop devices but it doesnot show ToolBar and TabLayout on Kitkat devices. But i can still swipe through 3 fragment as expected on kitkat device as well. How come same code written using google support libraries works differently on different devices!

I tried referring to [Toolbar is not visible on Android 4.X devices [solved] question but it didn't solve the problem. I tried running the code in emulator with API 19 but facing same issue on that as well.

I have added 'com.android.support:appcompat-v7:22.2.0', 'com.android.support:support-v4:22.2.0' and 'com.android.support:design:22.2.0' dependencies in the project.

or:

    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Solution 2

this happened to me and it was because i was using a CoordinatorLayout but i was not specifying the layout_behavior of the content. So you should do this in my case:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/cl_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    tools:ignore="MissingPrefix">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.CollapsingToolbarLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:contentScrim="@color/white"
            app:titleEnabled="false">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@android:color/white"
                android:elevation="4dp"
                app:layout_collapseMode="pin">

                <TextView
                    android:id="@+id/toolbar_title"
                    fontPath="fonts/Medium-Extd.otf"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="my toolbar title"
                    android:textAllCaps="true"
                    android:textColor="#000000"
                    android:textSize="14sp" />

            </android.support.v7.widget.Toolbar>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>


<!-- add the behavior here and the toolbar apppeared on 4.4 devices in my case -->
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" >

//...... blah blah

        </RelativeLayout>

I had problem in Android 4 and I solved it. See how. Need to move the toolbar to a higher level.

Top layout is CoordinatoLayout only but due to some editing issue it was not showing earlier. Could you please check it now and let me know if something is not right

[GPack]

change xmlns:app="http://schemas.android.com/tools" to xmlns:app="http://schemas.android.com/apk/res-auto"

[Vinit Thaker]

I changed it to "xmlns:app="schemas.android.com/apk/res-auto" but still i was facing the same issue and after adding "<item name="windowActionBarOverlay">false</item>" line inside style.xml file , as suggested by SilentKnight, it is working fine now.

[Vinit Thaker]

Thanks SilentKnight after adding windowActionBarOverlay property inside style.xml file, it is working fine now.

[GPack]

In my opinion, was the wrong namespace for app: prefix to produce the overlap.

[Vinit Thaker]

i was facing same issue even after changing the app prefix so i think it was not because of that. But i am facing this problem again i might have to post another question again.

[Partho63]

Please elaborate your answer with some explanations.
