Android - imageView.getDrawable() returns null

Question

I am stuck on this seemingly easy issue. What am I doing wrong ?

ImageView mImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState)          


        

Answer 1

You set the drawable to background attribute of 'src'.

android:background="@drawable/clip"

. So change yours activity_main.xml by replacing background attribute to src:

android:src="@drawable/clip"

Finally yours activity_main.xml will be:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

<ImageView
    android:id="@+id/image"
    android:layout_height="100dp"
    android:layout_width="100dp"
    android:scr="@drawable/clip"
    android:layout_centerHorizontal="true"
    />

Or you can get yours drawable by calling method getBackground() which returns drawable that was set by attribute android:background
