In my application I have Toolbar
in the MainActivity and inside the MainActivity I have a ViewPager
to show 4 fragment.
The toolbar
contains some images ( button
).
I want in one of these fragments to hide the image from the toolbar
. I wrote the code below, but it hides the image in all the fragments
.
My code:
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
troy.setVisibility(View.GONE);
}
}, 50);
}
}
I want to hide it just in my current fragment
, not all of them.
How can I do it?
You can use addOnPageChangeListener()
of your ViewPager
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener(){
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
if (position == 0) { // Condition may vary according to your needs...
troy.setVisibility(View.GONE);
} else {
troy.setVisibility(View.VISIBLE);
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
