android acitivitygroup button onClick make applicatoin crash

Question

So im developing a android application and im using a tabhost. To handle the activity's i created a activitygroup from every tab.

From these "parent" activity's i go to child acivity's.

on this child acitivy i have a page with a spinner and a button.

First the button was working but when i clicked on the spinner the application would crash. To fix this i had to change

setContentView(R.layout.sho_add_exercise_event); 

to

View contentView = LayoutInflater.from(getParent()).inflate(R.layout.show_add_exercise_event, null);
setContentView(contentView);

now my spinner is working but when i click on the button the application will crash.

This is the log output

Answer 1

I found the solution.

I deleted the onClick in the xml file. And added a setOnClickListener in my java code.

This did the job :) hope this helps some1 else out to!

Answer 2

Message is self-explanatory: Could not find a method onClickAdd(View) in the activity

Declare a method with this event:

public void onClickAdd(View v)
{
   .......
   .......
}

Because somewhere you have declared onClickAdd() method for Add button i think.
