horizontal recyclerview item width half of screen android

To set the width of the items in a horizontal RecyclerView to be half of the screen width in Android, you can use the RecyclerView.LayoutManager and set the width of the item view to be match_parent and the height to be wrap_content.

Here's an example of how to do it:

First, create a layout file for the item view with the desired dimensions:

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical">
  <!-- other layout elements go here -->
</LinearLayout>

Then, in your RecyclerView.Adapter, set the RecyclerView.LayoutManager to be a LinearLayoutManager with the horizontal orientation:

RecyclerView recyclerView = findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
recyclerView.setAdapter(new MyAdapter());

This will cause the items in the RecyclerView to be displayed horizontally, with the width of each item being set to match_parent (i.e., the full width of the screen).
