sometimes my app get a crash. I dont no why it doesent work sometimes, i didnt change anything. In my fragment i add 2 items on onViewCreated()
listview_products = (ListView) view.findViewById(R.id.listview_product_list);
mSwipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.productlist_swipe_refresh);
The error is this near (it's line 60)listview_products = (ListView) view.findViewById(R.id.listview_product_list);
This is my layout file:
<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/productlist_swipe_refresh"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/listview_product_list"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</android.support.v4.widget.SwipeRefreshLayout>
Why i get the error? What can i do to fix it?
