I want to expand my recyclerview on click on it but at the same time with this first click I do not want any recyclerview item to gain focus. Recyclerview item should gain focus on second click.

I would like you not to focus on expanding method but on gaining focus on recyclerview (or dummy parent layout '@+id/rll' if it can't be done without this) without gaining on recyclerview item. Recyclerview item should gain focus on second click.

Here is my simplified layout:

`<LinearLayout xmlns:android=";
    xmlns:tools=";
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?actionBarSize"
    android:orientation="vertical"
    android:weightSum="2">

    <RelativeLayout
        android:id="@+id/rll"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:descendantFocusability="blocksDescendants"
        android:clickable="true">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv_benchmarks"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginBottom="5dp"

            android:divider="#ffffff"
            android:dividerHeight="1dp"
            android:footerDividersEnabled="true"
            android:headerDividersEnabled="true"
            android:scrollbars="vertical" />

    </RelativeLayout>
</LinearLayout>`

I tried various combinations with descendandFocusability, focusable, focusableInTouchMode in different views and none ot these worked.

You can override onInterceptTouchEvent () to intercept click events, or you can try to understand the View's event distribution mechanism

public class CustomRelativeLayout extends RelativeLayout {
    private int clickCount = 0;
    private static final int REQUIRED_CLICKS = 2; // The number of clicks you need

    public CustomRelativeLayout(Context context) {
        super(context);
    }

    public CustomRelativeLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomRelativeLayout(
       Context context, 
       AttributeSet attrs, 
       int defStyleAttr
    ) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            clickCount++;
            if (clickCount >= REQUIRED_CLICKS) {
                clickCount = 0; // Reset click count
                return false; 
            }
        }
        return true; 
    }
}

Finally, use it in your layout

<LinearLayout xmlns:android="http://schemas.android/apk/res/android"
xmlns:tools="http://schemas.android/tools"
android:id="@+id/main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?actionBarSize"
android:orientation="vertical"
android:weightSum="2">

<com.yourpackage.CustomRelativeLayout
    android:id="@+id/rll"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:descendantFocusability="blocksDescendants"
    android:clickable="true">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/rv_benchmarks"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="5dp"
        android:divider="#ffffff"
        android:dividerHeight="1dp"
        android:footerDividersEnabled="true"
        android:headerDividersEnabled="true"
        android:scrollbars="vertical" />

    </com.yourpackage.CustomRelativeLayout>
</LinearLayout>
