RuntimeException and InflateException: Binary XML file line #7 .. followed by ClassCastException

Question

There are multiple questions about this problem, but none of the fixes I've read about seems to be working.

Fixes that didn't seem to work:

Fix 1: Android - InflateException: Binary XML file line #7

Fix 2: InflateException Binary XML file at line #7: Error inflating class fragment

Description of my problem:

I'm trying in incorporate a SliderView in my glassware. SliderView can be used as a custom loading screen.

1. Link I found - 2. Google Review Team Proposed Link

I'm currently using the first link.

During my application, I call upon SearchActivity.java which does a few things. I've commented most of the code to see the problem and it seems the problem first appears here:

protected void onCreate(Bundle bundle) {

        super.onCreate(bundle);
        setContentView(R.layout.activity_main);
}

Here is what can be found in my activity_main.xml: located in my res/layout/ :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/black">

<!-- The line right under is line number 7 -->
    <com.google.android.glass.sample.apidemo.card.SliderView
        android:id="@+id/indeterm_slider"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" />


    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:contentDescription="@string/banner_150"
        android:src="@drawable/websurg_icon_white_150" />

</RelativeLayout>

Yes, my SliderView is located in my com.google.android.glass.sample.apidemo.card package. Yes, my SliderView does have the three different required constructors.

public SliderView(Context paramContext) {
    this(paramContext, null);
}

public SliderView(Context paramContext, AttributeSet paramAttributeSet) {
    this(paramContext, paramAttributeSet, 0);
}

public SliderView(Context paramContext, AttributeSet paramAttributeSet, int paramInt) {
    super(paramContext, paramAttributeSet, paramInt);
    LayoutInflater.from(getContext()).inflate(R.layout.slider, this);
    this.slider = findViewById(R.id.slider_control);
    this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));
    hideSlider(false);
    hideIndeterminateSlider(false);
}

I'm getting two specific problems and that is:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.google.android.glass.sample.apidement/com.google.android.glass.sample.apidemeo.card.SearchActivity}:

and

android.view.InflateException: Binary XML file line #7: Error inflating class com.google.android.glass.sample.apidemo.card.SliderView

So my question is, what is causing these errors? What do I need to change for it to work?

UPDATE:

LayoutInflater.from(getContext()).inflate(R.layout.slider, this);
        this.slider = findViewById(R.id.slider_control);
        this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));

This is the default res/layout/slider xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="@dimen/slider_bar_height" >

    <View
        android:id="@id/slider_control"
        android:layout_width="0.0px"
        android:layout_height="@dimen/slider_bar_height"
        android:background="@android:color/white" />

    <ImageView
        android:id="@id/indeterminate_slider"
        android:layout_width="fill_parent"
        android:layout_height="@dimen/slider_bar_height"
        android:background="@drawable/slider_indeterminate" />

</FrameLayout>

Clean and rebuild to fix the case if your view ids are out of sync between R and binary XML files. — laalto

Any reasons for using a custom View instead of the Slider API? — Alain
– Alain, Commented Nov 25, 2014 at 17:58
I attempted to publish my glassware and the review team didn't mention the api. They just gave me a message and a link towards github to create progressbars. I don't know if this answers your question or not. "Eventually, we hope to have the progress bars easier to build with the GDK. Until that time, check out this sample from one of our Explorers: github.com/w9jds/GDK-ProgressBar. " — kemicofa

Update: The solution was the following:

In your SliderView.java constructor ( public SliderView(Context paramContext, AttributeSet paramAttributeSet, int paramInt) ):

Change:

this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterm_slider));

to:

this.indeterminateSlider = ((ImageView) findViewById(R.id.indeterminate_slider));

In your slider.xml (located in res/layout/ ) :

Change:

<ImageView
        android:id="@id/indeterminate_slider" [...] />

To:

<ImageView
    android:id="@+id/indeterminate_slider" [...] />

The main problem is getting your SliderView.java to point to the right id. Since this wasn't done you were getting a InflateException. Once that was fixed, you were getting a ClassCastException. This came from your slider.xml not having that +

indeterm_slider is the SliderView, and you are casting to ImageView. You got the InflateException because your view can not be created due of this ClassCastException

What would you recommend I do?

Blackbelt Over a year ago

assign an id to ImageView and look for the correct id?

kemicofa Over a year ago

Working on it, I'll let you know if it works or not.

Blackbelt Over a year ago

I mean, android:id="@id/indeterminate_slider", should probably be android:id="@+id/indeterminate_slider", and you should look for indeterminate_slider not for indeterm_slider

kemicofa Over a year ago

yeah sorry. My head is fuzzy. Been working on this thing all day. Ok, it seems that it was indeterminate instead of indeterm. Now I just need to take care of the cast exception.

Consider using the new Slider API that was released in XE22. It is much easier to use and doesn't require you to alter your layouts since it is treated as a global UI component.
