RecyclerView CardView'un kenarlarını kesip ayırma

Question

Programlı olarak CardView'leri başlatan bir RecyclerView var. Kartın sol tarafı kesiliyor ve ortalanmıyor. Yayınlanan başka bir kod gerekiyorsa, bunu yapmaktan memnuniyet duyarım. İşte

bazı yararlı kodudur:

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools"

Answer 1

, metin merkezi haline match_parent için TextView genişliğini değiştirmek için

<RelativeLayout android:id="@+id/card_layout" 
    > 

     <TextView android:id="@+id/student_name" 
      android:layout_width="match_parent" // before it is wrap_content 
      ... /> 

    </RelativeLayout> 

sizin alt merkezini doğru

// I organize the flow of your layout from left-to-right 
// Before it is right-to-left 

<android.support.v7.widget.Toolbar android:id="@+id/card_toolbar" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     android:layout_gravity="bottom"> 

     <ImageView android:id="@+id/student_absent" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_gravity="bottom|start" 
      android:layout_marginBottom="25dp" 
      android:src="@drawable/ic_change_history_black_24dp"/> 

     <ImageView android:id="@+id/student_delete" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_gravity="bottom|end" 
      android:layout_marginBottom="25dp" 
      android:src="@drawable/ic_delete_black_24dp"/> 

    </android.support.v7.widget.Toolbar>
