android - RecyclerView within CardView center_vertical -


hello have recyclerview within cardview. want text of recyclerview in center_vertical within cardview.

cardview xml is:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:card_view="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="wrap_content">      <android.support.v7.widget.cardview         android:id="@+id/item_breakfast"         android:layout_width="match_parent"         android:layout_height="@dimen/item_breakfast_height"         card_view:cardcornerradius="@dimen/item_breakfast_corner">          <relativelayout xmlns:app="http://schemas.android.com/apk/res-auto"             android:layout_width="match_parent"             android:layout_height="match_parent">              <!-- icon breakfast -->             <de.hdodenhof.circleimageview.circleimageview                 android:id="@+id/breakfast_icon"                 android:layout_width="@dimen/item_breakfast_circleviewsize"                 android:layout_height="@dimen/item_breakfast_circleviewsize"                 android:layout_centervertical="true"/>              <android.support.v7.widget.recyclerview                 android:id="@+id/list_food"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:layout_torightof="@+id/breakfast_icon"                 android:layout_centerinparent="true"                 android:scrollbarstyle="insideoverlay"/>         </relativelayout>     </android.support.v7.widget.cardview>  </linearlayout>

the recyclerview xm is:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_centervertical="true">     <!-- food  -->     <textview         android:id="@+id/food"         android:layout_width="wrap_content"         android:layout_height="wrap_content"/> </linearlayout>

the textview id "food" isn't center_vertical. why?

use layout_gravity center textview inside layout:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_centervertical="true">      <!-- food  -->     <textview         android:id="@+id/food"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical" /> </linearlayout>

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
