请使用Java帮我写一个申明安卓类控件

public class AndroidWidget extends View {

public AndroidWidget(Context context) {
    super(context);
}

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

public AndroidWidget(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    // Add your drawing code here
}

// Add any additional methods or properties here
