When I pull down my SwipeRefreshLayout
it is working, but as you can see in the above code I have a scroll view inside that. So when I am pulling down my scroll view, it goes down and half the images are not showing because it came down. When I am trying to pull up again my scroll view is not going up. Instead, SwipeRefreshLayout
is getting call. What should i do?
Please help me out.
I would say it's better to have an extended SwipeRefreshLayout with listener to be able to add various conditions from the classes that display this layout.
Something like the following: GeneralSwipeRefreshLayout.java
public class GeneralSwipeRefreshLayout extends SwipeRefreshLayout {
private OnChildScrollUpListener mScrollListenerNeeded;
public interface OnChildScrollUpListener {
boolean canChildScrollUp();
}
public GeneralSwipeRefreshLayout(Context context) {
super(context);
}
public GeneralSwipeRefreshLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
/**
* Listener that controls if scrolling up is allowed to child views or not
*/
public void setOnChildScrollUpListener(OnChildScrollUpListener listener) {
mScrollListenerNeeded = listener;
}
@Override
public boolean canChildScrollUp() {
if (mScrollListenerNeeded == null) {
Log.e(GeneralSwipeRefreshLayout.class.getSimpleName(), "listener is not defined!");
}
return mScrollListenerNeeded != null && mScrollListenerNeeded.canChildScrollUp();
}
}
And then inside your class that displays SwipeRefreshLayout containing ListView or GridView layout, you can do something like this:
mSwipeLayout.setOnChildScrollUpListener(new OnChildScrollUpListener() {
@Override
public boolean canChildScrollUp() {
return mListView.getFirstVisiblePosition() > 0 ||
mListView.getChildAt(0) == null ||
mListView.getChildAt(0).getTop() < 0;
}
});
