Android CardView Detailed

Android5.0 introduces us to a completely new control –cardview, which, in essence, can be seen as framelayout adding rounded corners and shadow effects on top of itself. Please note that the CardView is packaged as a layout and is often used as a container in the item layout of ListView and Recyclerview.

Found a good-looking dongdong cardview, he in support V7 bag ~ ~

As the name suggests is the card view, you can set shadows, rounded corners, and so on.

Looks like this:

Or you can put it in the ListView:

How to use

Secondly, it introduces its basic properties:

App:cardbackgroundcolor This is setting the background color
App:cardcornerradius this is to set fillet size
App:cardelevation This is the shadow that sets the Z axis
App:cardmaxelevation This is the maximum height value of the z axis set
App:cardusecompatpadding whether to use compatpadding
App:cardpreventcorneroverlap whether to use Preventcorneroverlap
App:contentpadding Set the content padding
App:contentpaddingleft set the left padding of content
App:contentpaddingtop set content on padding
App:contentpaddingright set the right padding of the content
App:contentpaddingbottom set the bottom of the content padding

Add a CardView to the XML file

 <android.support.v7.widget.cardview xmlns:card_view= "Http://schemas.android.com/apk/res-auto"
    android: Layout_width= "200DP"
    android:layout_height= "wrap_content"
    <--! set CardView background color-->
    Card_view: Cardbackgroundcolor= "#303069"

    <--! set CardView radius-->
    card_view:cardcornerradius= "10DP"
    card_ View:cardpreventcorneroverlap= "true"
    card_view:cardusecompatpadding= "true"

    <--! setting CardView padding-- >
    card_view:contentpadding= "10DP" >
    <textview
      android:text= "I am CardView"

      android: Textcolor= "#fff"
      android:layout_width= "wrap_content"
      android:layout_height= "wrap_content"/>

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

Inside can wrap content, through observation source code we found that CardView is actually a framelayout, so use the same way as Framelayout

public class CardView extends Framelayout implements Cardviewdelegate {
}

Or you can also be used for listview~~ anyway very simple beautiful is AH ~ ~

In the future meet what fillet demand, you can use this to complete, and not what Porterduffxfermode ~ ~
