I have a library with following methods:
Calling this in B4A with MyLib.ReplaceEditText(EditText1) for example works well.
Now I want to simplify the usage and provide just a ReplaceView() method that calls the other methods depending on the type of view in the parameter.
I tried the following method:
But this does not work because now if I call MyLib.ReplaceView(EditText1) the parameter is of type android.view.EditText and not EditTextWrapper as I expected. I tried with different parameter types like ViewWrapper. But then I get a ClassCastException when I try to cast the parameter to the correct type for ReplaceEditText().
So what I don't understand is why is the EditText1 object of type android.view.EditText if I declare the parameter as Object and of type anywheresoftware.b4a.objects.EditTextWrapper if I declare the parameter as EditTextWrapper. Is this done by the Java compiler? Is there any solution for my problem? I need the wrapper object as the parameter.
B4X:
public void ReplaceEditText(BA ba, EditTextWrapper View) {
...
}
public void ReplaceCheckBox(BA ba, CheckBoxWrapper View) {
...

Common.Log("No View replacement needed for Lollipop or above");
} else {
if (View instanceof EditTextWrapper) {
Common.Log("Replace an EditText View");
ReplaceEditText(ba, (EditTextWrapper) View);
} else {
Common.Log("Replacing of " + View.getClass().toString()
+ " not supported!");
}
