0LongLongAgo commented 8 years ago

how to solve this problem?

jjhesk commented 8 years ago

@skysmileereryday maybe you can illustrate from your source code first.

castrojr913 commented 8 years ago

The same error, in my scenario the message is read instead of write from field.... I'm using the easyRegularAdapter and meanwhile I'm scrolling down, the app crashes

Check if onCreateViewHolder doesn't return null.

i solve by just use WrapContentLinearLayoutManager class instead of direct use LinearLayoutManager and create one class WrapContentLinearLayoutManager.java look like below.

public class WrapContentLinearLayoutManager extends LinearLayoutManager { //... constructor public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) { super(context, orientation, reverseLayout); }

public WrapContentLinearLayoutManager(Context context) {
    this(context, VERTICAL, false);
}

@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
    try {
        super.onLayoutChildren(recycler, state);
    } catch (Exception e) {
        if (EdConstant.LOG_ENABLED) {
            Timber.e("Error, IndexOutOfBoundsException in RecyclerView happens" + e);
        }
    }
}

}
