Question

I just changed my application’s(2.2) version into 1.5. After, that i’ve an error in my XML files like this

error: No resource identifier found for attribute 'onClick' in package 'android'

Why i can’t use that method. Otherwise, is there any additional jars are available to use this method in Android version 1.5. Anyone tell me.

Answer 1

onClick attribute is not defined for API 3 and less. (Android <= 1.5)

It works since API 4 (Android 1.6)

EDIT

If you want compatibility you can use:

findViewById(R.id.myButton).setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        // Do stuff
    }
});
