Android的布局XML中app：srcCompat和android：src之间的区别

当我用android：src更改app：srcCompat时,错误消失但图标看起来像素化了.

两者之间的主要区别是什么

app:srcCompat="@drawable/ic_play"

和

android:src="@drawable/ic_play"

is the most foolproof method of integrating 07001 into your app.Vector drawables allow you to replace multiple png assets with a single vector graphic, defined in XML. While previously limited to Lollipop and higher devices

注意

截至Android Support Library 23.3.0,支持向量drawable只能通过app：srcCompat加载.

您需要将vectorDrawables.useSupportLibrary = true添加到build.gradle文件中

    // Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
    }  
 }  

android:src

Sets a drawable as the content of this ImageView.It will display in
its original size. No automatic scaling .
