ConstraintLayout onMeasure very slow

Question

so I tried refactoring some of my recycler ViewHolders to ConstraintLayouts. After I did it I was shocked after what I saw. Inflating a single view takes 20x more time than usual LinearLayout. It actually skips so many frames while doing it.

EDIT: Version of constraint layout is not relevant. Tried different combinations had almost the same results.

Can any one explain why is this happening? Maybe it's not designed for such "heavy" views?

Here is a root XML that is used in ViewHolder:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/white"
    android:elevation="@dimen/param_2"
    android:orientation="vertical"
    android:stateListAnimator="@animator/material_selector">

    <LinearLayout
        android:id="@+id/order_view_tabs_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="@dimen/param_2"
        android:padding="@dimen/param_4"
        android:background="@color/white"
        android:divider="@drawable/empty_horizontal_divider"
        android:elevation="@dimen/param_2"
        android:orientation="horizontal"
        android:showDividers="middle"
        android:visibility="gone"/>

    <include layout="@layout/order_list_item_constraint"/>

    </LinearLayout>

And here is order_list_item_constraint.xml

Here is proof of problem. All child views have measure times around 0.1ms

Comparing a simple LinearLayout

EDIT2: Here is a layout version with LinearLayout's: https://pastebin.com/ZvffUHnw

Answer 1

That's definitely not expected -- I'll have to investigate more to see what's causing it. Note that 1.1 beta is right now going to be slower than 1.0, all the optimizer passes aren't enabled. At first glance there's a lot of textview with 0dp width, which is pretty costly -- like with linear layout, 0dp is going to result in a double measure. E.g. instead of:

<TextView
    android:id="@+id/order_list_item_order_title"
    android:layout_width="0dp"
    android:layout_height="20dp"
    android:layout_marginTop="4dp"
    android:text="@string/main_swipe_list_item_info_title_order"
    app:layout_constraintEnd_toEndOf="@id/mid_guideline"
    app:layout_constraintStart_toStartOf="@id/start_guideline"
    app:layout_constraintTop_toBottomOf="@+id/delivery_status"/>

You could do:

<TextView
    android:id="@+id/order_list_item_order_title"
    android:layout_width="wrap_content"
    android:layout_height="20dp"
    android:layout_marginTop="4dp"
    android:text="@string/main_swipe_list_item_info_title_order"
    app:layout_constraintStart_toStartOf="@id/start_guideline"
    app:layout_constraintTop_toBottomOf="@+id/delivery_status"/>

You don't need to have both a start and end constraints here as well, as you are using guidelines.

Note that in general, HierarchyViewer isn't going to be giving you accurate measurements (that said with such a difference, something seems wrong there).

How does your com.express.mobile.customView.MyNetworkImageView custom view handles measures? as you set it to 0dp it will also be double-measured in your layout.

Finally, Could you add what's in your included layout order_list_item_map_interval_box ?

edit 1.1 beta 6 should improve performances quite a log
