How to set VectorDrawable as an image for ImageView programmatically

I want to set some vectorDrawables to a ImageView in Android Studio.

I can set png and jpg drawable easily but when i want to set VectorDrawable, it does not work on imageview.

img.setImageResource(R.drawable.ic_home);

ic_home is VectorDrawable and this code doesn't work.

Solution 1:

If you want to use vector drawables (less OR greater than API 21) just do the following:

Set the image programmatically (e.g. in your activity):

imageView.setImageResource(R.drawable.ic_left_arrow_blue);

or by XML:

app:srcCompat="@drawable/your_vector_name"

In your app's build.gradle you need to include:

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

And for vector support for less then API 21, add the following to onCreate:

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

Solution 2:

For those who want to load a vector drawable programmatically for other uses, such as setting a drawableLeft or otherwise, you can use:

Drawable drawable = AppCompatResources.getDrawable(context, drawableRes);

where the context is a AppCompatActivity.

Solution 3:

As per official android developer blog, no changes for setImageResource() method at runtime for vectorDrawables.

If you’re changing drawables at runtime, you’ll be able to use the same setImageResource() method as before - no changes there. Using AppCompat and app:srcCompat is the most foolproof method of integrating vector drawables into your app.

For more details, check out this nice article AppCompat — Age of the vectors by Google Developer.

Solution 4:

if you are concerned with the backward compatibility then you should use AppCompatImageView instead of image view. go through the code below.

<android.support.v7.widget.AppCompatImageView
    android:id="@+id/iv_about"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
   app:srcCompat="@drawable/ic_vector_image"
    />

java

AppCompatImageView image = (AppCompatImageView) findViewById(R.id.iv_about);
image.setImageResource(R.drawable.ic_vector_image);

below code need to add in build.gradle

android { defaultConfig{ vectorDrawables.useSupportLibrary = true } }

And it will serve the perspective of app:srcCompat.

Solution 5:

for Java Code use:

formate_img.setImageResource(R.drawable.ic_text);//ic_text is a Vector Image

and for XML use:

<android.support.v7.widget.AppCompatImageView
        android:id="@+id/search_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:layout_weight="1"
        ads:srcCompat="@drawable/ic_barcode" //for Vector Image
        tools:ignore="VectorDrawableCompat" />
