Hi Guys, Maybe you all are expert in terms of using RecyclerView in android. This blog is simple example for using filter option with RecyclerView adapter. As for now you will instantiate RecyclerView and set the adapter to RecyclerView as following way. RecyclerView list = (RecyclerView) findViewById(R.id.list); list.setLayoutManager(new LinearLayoutManager(this)); list.setHasFixedSize(true); ArrayList<Number> numbers = new ArrayList<>(); String ONEs[] = {"ZERO", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE", "TEN"}; String TENs[] = {"ZERO", "TEN", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY", "SEVENTY", "EIGHTY", "NINETY", "HUNDRED"}; String HUNDREDS[] = {"ZERO", "HUNDRED", "TWO HUND...
Consider using simple NavigationView instead of this old sliding menu , which based on Material design and much simpler and very flexible than this Navigation drawer.
This post will help you to create a simple sliding menu in Android.
Here sliding menu is a listview which is in INVISIBLE state. It will comes to VISIBLE state once you click the menu button. And it will go to INVISIBLE state again once you pick the item from listview. To change the state we are using animation, that is why it looks like sliding.
