android.view.InflateException: Binary XML file

Question

I'm getting this strange error in the logcat and I've tried everything that came to my mind to solve it and still getting it. Here is the logcat:

and this is my xml:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bitdraw="http://schemas.android.com/apk/res/com.dm.test" >

    <view
    class="com.dm.test.ui.BitCanvasActivity$CanvasView"
    android:id="@+id/backgroundz"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

    <com.dm.test.widget.ActionButtons
        android:id="@+id/btn_actions"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:layout_marginBottom="135dp"
        android:layout_gravity="bottom|center_horizontal" />


    <com.dm.test.widget.ColorPicker 
        android:id="@+id/color_picker"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center_horizontal"
        android:orientation="horizontal" 
        bitdraw:colors="@array/color_picker_colors"
        bitdraw:cols="3"  
        bitdraw:fils="5" />

</merge>

and on the .java line 55 its this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate( savedInstanceState );
    setContentView( R.layout.bit_canvas ); //line 55
    mActionButtons = ( ActionButtons ) findViewById(R.id.btn_actions);
    mColorPicker = ( ColorPicker ) findViewById( R.id.color_picker );

and this is part of the inner class:

public class CanvasView extends View {

    public CanvasView(Context c) {
        super(c);
    }

    public CanvasView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CanvasView (Context c, AttributeSet atr, int defstyle){
        super(c, atr,defstyle);
    }

    @Override
    protected void onDraw(Canvas canvas) { ... }

Any help would be much appreciated, because I seriously ran out of ideas :S

You need to declare the inner class static. See this [answer on stackoverflow][1] [1]: stackoverflow.com/questions/4483433/… — Jordi Coscolla

Try changing your layout for the one below, since on that way you will be calling the class item.

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bitdraw="http://schemas.android.com/apk/res/com.dm.test" >

    <com.dm.test.ui.BitCanvasActivity.CanvasView
    android:id="@+id/backgroundz"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

    <com.dm.test.widget.ActionButtons
        android:id="@+id/btn_actions"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:layout_marginBottom="135dp"
        android:layout_gravity="bottom|center_horizontal" />


    <com.dm.test.widget.ColorPicker 
        android:id="@+id/color_picker"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center_horizontal"
        android:orientation="horizontal" 
        bitdraw:colors="@array/color_picker_colors"
        bitdraw:cols="3"  
        bitdraw:fils="5" />

</merge>

if that doesn't work try making your class as jordi said.

You need a "handler" to modify the Android interface within a Thread.

See http://developer.android.com/reference/android/os/Handler.html.
