super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);



final xsPagerAdapter adapter = new xsPagerAdapter();
myPager = (ViewPager) findViewById(R.id.xspanelpager);
myPager.setAdapter(adapter);
myPager.setCurrentItem(1);


myPager.setOnPageChangeListener(new OnPageChangeListener() {

public void onPageSelected(int position) {
// TODO Auto-generated method stub

iExPosition = myPager.getCurrentItem();

switch (position) {
case 0:
btnStisni = (Button)findViewById(R.id.btnStisni1);
btnStisni.setOnClickListener(new View.OnClickListener() {


public void onClick(View v) {
myPager.setCurrentItem(1);
}
});
