android.view.InflateException: Binary XML file line #94: Error inflating class

Question

Running into a slight Inflation issue while trying to implement the micode open source compass into my app. So I am trying to figure out how to fix this. Another set of eyes looking at this would be good. So here we go:

Here is the class that this is relating to:

package styckz.com.clearpicturemode;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class CompassView extends ImageView {
private float mDirection;
private Drawable compass;

public CompassView(Context context) {
    super(context);
    mDirection = 0.0f;
    compass = null;
}

public CompassView(Context context, AttributeSet attrs) {
    super(context, attrs);
    mDirection = 0.0f;
    compass = null;
}

public CompassView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    mDirection = 0.0f;
    compass = null;
}

@Override
protected void onDraw(Canvas canvas) {
    if (compass == null) {
        compass = getDrawable();
        compass.setBounds(0, 0, getWidth(), getHeight());
    }

    canvas.save();
    canvas.rotate(mDirection, getWidth() / 2, getHeight() / 2);
    compass.draw(canvas);
    canvas.restore();
}

public void updateDirection(float direction) {
    mDirection = direction;
    invalidate();
}

}

So here we are... I tried turning that class above from public to static to no avail as per the request in another thread and it did not work... Maybe I am doing something wrong? All that did was make the class name highlight red below it and claim that static was invalid.

Any ideas?

Answer 1

the problem is you have the wrong path in your xml.

you have CompassView as being located in net.micode.compass. but it is actually located in styckz.com.clearpicturemode

so change that in your xml

this

<net.micode.compass.CompassView
   android:id="@+id/compass_pointer"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_gravity="center"
   android:src="@drawable/compass" />

should look like this

<styckz.com.clearpicturemode.CompassView
   android:id="@+id/compass_pointer"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_gravity="center"
   android:src="@drawable/compass" />
