Android Vector Drawable App:Srccompat Not Showing Images

Android vector drawable app:srcCompat not showing images

Original Answer

Use android.support.v7.widget.AppCompatImageView instead of ImageView in your layout, like this:

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

  <android.support.v7.widget.AppCompatImageView
    android:tint="#d74313"
    app:srcCompat="@drawable/circle_icon"
    android:layout_width="30sp"
    android:layout_height="30sp" />

  <android.support.v7.widget.AppCompatImageView
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    app:srcCompat="@drawable/lauzaviete"
    android:layout_width="25dp"
    android:layout_height="25dp" />
</LinearLayout>

See the AppCompatImageView docs here and app:srcCompat here.

Also, make sure to do the following:

Setup your build.gradle

android {
  defaultConfig {
    vectorDrawables {
      useSupportLibrary = true
    }
  }
}

Docs: https://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.VectorDrawablesOptions.html#com.android.build.gradle.internal.dsl.VectorDrawablesOptions:useSupportLibrary

Extend your Activity with AppCompatActivity

public final class MainActivity extends AppCompatActivity {    
  @Override protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
  }
}

When using app:srcCompat, make sure to have the correct declarations in your layout:

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

Optional (warning: please read docs): setCompatVectorFromResourcesEnabled in your Application class

public class App extends Application {

  @Override public void onCreate() {
    super.onCreate();

    // Make sure we use vector drawables
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
  }
}

Docs: https://developer.android.com/reference/android/support/v7/app/AppCompatDelegate.html#setCompatVectorFromResourcesEnabled(boolean)

VectorDrawable not showing or drawed wrong

VectorDrawable added in API level 21.

Support Library 23.2 or higher provides full support to Vector
Drawables and Animated Vector Drawables on devices running Android 5.0
(API level 21) or lower.

You should use

 app:srcCompat="@drawable/your_vector_image"

You need to add vectorDrawables.useSupportLibrary = true to your build.gradle file:

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

FYI

app:srcCompat attribute to reference vector drawables as well as any
other drawable available to android:src.

Vector drawable not showing in app icon below 5.0 api level

Try adding your icon as an "Image Asset," so that all the different DPI (dots per inch) versions of the icon are created.

This will make sure that your icon is handled even at lower resolution versions.
