Problem statement:
RecyclerView is often used for layout in development, and then when the interface is started, because there is a delay in obtaining data from databases or networks, etc., when the data is not obtained and RcyclerView is loaded, RecyclerView: No adapter attached will appear; The skipping layout causes the APP to crash for no reason.
Solution:
First hide the layout setVisibility(View.GONE) of RecyclerView, optimize some and add a loading screen, and then hide the layout setVisibility(View.VISIBLE) of RecyclerView after the data is loaded, and hide the loading screen.
The following is a simple display in pseudocode:
onCrete{
pbLoading.setVisibility(View.VISIBLE);
RecyclerView.setVisibility(View.GONE);
监听数据加载完成后
pbLoading.setVisibility(View.GONE);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(activity);
RecyclerView.setLayoutManager(linearLayoutManager);
RecyclerViewAdapter = new RecyclerViewAdapter(this,数据);
RecyclerView.setVisibility(View.VISIBLE);
RecyclerView.setAdapter(calendarAdapter);
}
