[Question] NullPointerException in AS Preview about materialviewpager HOT 10 CLOSED

Hi,

at line 70 I have the following code :
headerBackgroundContainer.addView(LayoutInflater.from(getContext()).inflate(settings.headerLayoutId, headerBackgroundContainer, false));

reading your issue it's LayoutInflater.from(getContext() has an issue

can you try set a custom layout as header :

header.xml

    <?xml version="1.0" encoding="utf-8"?>
    <com.github.florent37.materialviewpager.MaterialViewPagerImageHeader
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@id/materialviewpager_imageHeader"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    android:scaleType="centerCrop" />

and in your materialviewpager :

app:viewpager_header="@layout/header.xml"

I am creating a new project and import my lib from gradle to check if I have the same issue

from materialviewpager.

Ok it's just because header_logo.xml was only defined on my sample project,
I update the readme to alert create your own header layoit

mine was

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/logo_white"
    android:layout_width="wrap_content"
    android:layout_height="@dimen/materialviewpager_logoHeight"
    android:text="Material is Good"
    android:textSize="30sp"
    android:textColor="@android:color/white"/>

from materialviewpager.

I send you my empty project if you want to test :

https://github.com/florent37/TutosAndroidFrance/tree/master/MaterialViewPagerSample

can you confilm me it's working, so I can close this issue ?

Hey,
thanks for your fast reply, but I already implemented the header_logo.xml!
The issue with the Android Studio Design preview is still present - exact the same Rendering Problem. The App looks like this:

from materialviewpager.

look again my Readme I added a section about the style : https://github.com/florent37/MaterialViewPager#usage

from materialviewpager.

Works fine now, thanks!
One last (issue?):
I got a "AppCompat does not support the current theme features"-bug. Had to add item name="windowNoTitle">true</item to the styles under windowActionBar. (http://stackoverflow.com/questions/29790070/upgraded-to-appcompat-v22-1-0-and-now-getting-illegalargumentexception-appcompa)

Thanks for your patience!

from materialviewpager.

it's a current bug with appcompat 22.1.1, try to return at 22.0.0

from materialviewpager.

Okay, thanks for the information!

from materialviewpager.

information : I updated my empty sample
https://github.com/florent37/TutosAndroidFrance/tree/master/MaterialViewPagerSample

with an adapter & style
