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>

Answer 1

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

Answer 2

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.
