我有一个 ViewPager Activity 调用代表幻灯片布局的片段。
我需要的是通过捆绑将值从活动传递到片段。我怎么能这样做?我尝试在 onCreate() 中传递一个 int 2 但不起作用,我
活动:
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_screen_slide);
Intent intent = new Intent(this,ScreenSlidePageFragment.class);
Bundle bundle = new Bundle();
bundle.putInt("SIDE",2);
intent.putExtras(bundle);
/**
* Instantiate a ViewPager and a PagerAdapter
*/
mPager = (ViewPager)findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
mPager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(int arg0) {
if(itemOld > arg0){
auxBack--;
SIDE=1;
}
else if(itemOld < arg0){
auxFront++;
SIDE=0;
}
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
});
}
@Override
public void onBackPressed(){
if(mPager.getCurrentItem()==0){
super.onBackPressed();
}else{
mPager.setCurrentItem(mPager.getCurrentItem()-1);
}
}
/**
* A simple pager adapter that represents 5 ScreenSlidePageFragment objects, in sequence
*/
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter{
public ScreenSlidePagerAdapter(FragmentManager fm){
super(fm);
}
@Override
public ScreenSlidePageFragment getItem(int arg0) {
return new ScreenSlidePageFragment();
}
@Override
public int getCount() {
//Toast.makeText(getApplicationContext(), "Num pages " + NUM_PAGES, Toast.LENGTH_LONG).show();
return NUM_PAGES;
}
}
}
分段:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
int tID = ((ScreenSlidePagerActivity)getActivity()).getIntent().getExtras().getInt("SIDE");
Toast.makeText(getActivity(), "Side selected....." +tID, Toast.LENGTH_LONG).show();
