Hello, I am new to android programming...so please be patient..
I am trying to load a custom view (TracciaView) into an activity (Activitygps), where my custom view in defined as a subclass of an activty class. I created the following xml layout file for the activity containing the custom view:
----
<?xml version="1.0" encoding="utf-8"?>
<view xmlns:android="http://schemas.android.com/apk/res/android"
class="com.example.android.prova.Activitygps$Tracc iaView"
android:id="@+id/TracciaV"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
----
this is the subclass TracciaView:
public static class TracciaView extends View {
private ShapeDrawable mDrawable;
public TracciaView(Context context) {
super(context);
int x = 10;
int y = 10;
int width = 300;
int height = 200;
mDrawable = new ShapeDrawable(new OvalShape());
mDrawable.getPaint().setColor(0xff74AC23);
mDrawable.setBounds(x, y, x + width, y + height);
}
@Override protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
super.onDraw(canvas);
}
}
What happens is I am keeping on getting runtime error (the app dies), looking in the LogCat I get:
