Strange problem overriding one of LinearLayout's constructors

For some reason, Eclipse doesn't like the call to super(context, attrs, defStyle), yet it's happy with the other super calls. The error is "The constructor LinearLayout(Context, AttributeSet, int) is undefined".

I don't think the problem is with this code itself, but something else in the project's settings or something, since I adapted almost identical code from an example that did the same thing but for a RelativeLayout, which ran fine on my Eclipse setup in a test project.

Please Help :)

public class MyLinearLayout extends LinearLayout {

public MyLinearLayout(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    myInit();
}

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

public MyLinearLayout(Cont开发者_运维问答ext context, int checkableId) {
    super(context);
    myInit();
}

According to these javadocs the error is completely correct.

LinearLayout does not have that constructor. These are the two valid constructors:

LinearLayout(Context context) 
LinearLayout(Context context, AttributeSet attrs, Map inflateParams)

According to the developer site, the LinearLayout(context, attrs, defStyle) constructor is only available in API version 11, so it won't work in earlier versions.
