button click listener for button inside tab

[Rahkar Pouya]

i use smart tab, and add some activity to smart tab adapter as smart tab inner pages. now how can i handle button click for inner page? i don't want to use fragment solution.
this is my smart tab code in main activity:

ViewPagerItemAdapter adapter = new ViewPagerItemAdapter(ViewPagerItems.with(this)
            .add("aaa", R.layout.activity_home)
            .add("bbb", R.layout.activity_home)
            .create());
    ViewPager viewPager = (ViewPager) findViewById(R.id.container);
    viewPager.setAdapter(adapter);

    SmartTabLayout viewPagerTab = (SmartTabLayout) findViewById(R.id.viewpagertab);

and i add click listner in inner activity "aaa.java" also:

myButton= findViewById(R.id.myButton);
    myButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //some code
        }
    });

but nothing happen!
thanks in advance
