android-recyclerview

问题 I am trying to achieve following structure (image below). As you can see there are two sections with RecyclerView s and CardView s in it. These two sections are divided by two TextView s with Button s. Each section should match screen width (minus indent between cards). Each CardView has square ImageView in it.

Here is the layout for the item: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="160dp">

问题 I have a simple app with a viewpager containing 3 fragments. In one of the fragments I have Recyclerview list. When scrolling down, the toolbar is collapsed and when scrolling up is shown.

问题 It is my third day now dealing with the handling of my view clicks. I originally was using ListView , then I switched to RecyclerView . I have added android:onclick elements to every control on my row_layout and I am handling them in my MainActivity like this: public void MyMethod(View view) {} In my old ListView implementation, I have done setTag(position) to be able to get it in MyMethod by doing this inside it: Integer.parseInt(view.getTag().toString()) This worked nicely without problems.

问题 I'm trying to use RecyclerView in my application with lots of data in it and would like to make a fast scroll for it, just like for the ListView . Approach from this answer worked for me with ListView , but does not work for the RecyclerView . Even if I set fast scroll to true in RecyclerView layout, it still does not work: <android.support.v7.widget.RecyclerView android:id="@+id/recycler_view" android:scrollbars="vertical" android:layout_width="match_parent" android:layout_height="match
