Android中的模糊svg图像

Question

I added a user svg image from this website. The image should be sharp, but when i use it in my app as a default user image it is very blurry.

<!-- Thumbnail Image -->
<com.android.volley.toolbox.NetworkImageView
   android:id="@+id/thumbnail"
   android:background="@drawable/ic_icon_user"
   android:layout_width="80dp"
   android:layout_height="80dp"
   android:layout_alignParentLeft="true"
   android:layout_marginRight="8dp" />

Also how would I edit a svg image color in android. I tried adding a custom color, but it didn't work.

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportHeight="24"
    android:viewportWidth="24">
       <path
            android:fillColor="@color/ColorRed"
            android:pathData="M12,4A4,4 0 0,1 16,8A4,4 0 0,1 12,12A4,4 0 0,1 8,8A4,4 0 0,1 12,4M12,14C16.42,14 20,15.79 20,18V20H4V18C4,15.79 7.58,14 12,14Z" />
</vector>

Answer 1

Adding this to app build.gradle helped me to fix the problem with blurry svg images:

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

1. In Android Manifest.xml, set for your activity (blur doesn't work when hardware acceleration is true)

    android:hardwareAccelerated="false" 

2. You can disable hardware acceleration on the VIEW level:

    myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); 

Answer 3

Well similar problem happened to me. I was using

app:srcCompat="@drawable/your_image". 

Turns out this was causing the problem. You need to change it to this:

android:src="@drawable/your_image".
