How to use custom ImageView

Question

I found the following code on how to get the height and width of the display from ImageView: Trying to get the size of the image in ImageView . When I try to use it in the snippet below, I get the following error.

<com.mycompany.widget.SizeAwareImageView android:id="@+id/account_profile_img" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="@drawable/avatar" android:clickable="true" android:gravity="bottom|center_horizontal" android:onClick="onEditPhotoClicked" /> 

ERROR:

UPDATE

From the graphic layout I also get an error

 java.lang.NullPointerException Exception details are logged in Window > Show View > Error Log java.lang.NullPointerException at com.company.myapp.widget.SizeAwareImageView.onMeasure(SizeAwareImageView.java:66) at android.view.View.measure(View.java:15848) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:5008) at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1404) at android.widget.LinearLayout.measureHorizontal(LinearLayout.java:1052) at android.widget.LinearLayout.onMeasure(LinearLayout.java:590) at android.view.View.measure(View.java:15848) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:5008) at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1404) at android.widget.LinearLayout.measureVertical(LinearLayout.java:695) at android.widget.LinearLayout.onMeasure(LinearLayout.java:588) at android.view.View.measure(View.java:15848) at android.widget.RelativeLayout.measureChildHorizontal(RelativeLayout.java:728) at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:477) at android.view.View.measure(View.java:15848) at android.widget.ScrollView.measureChildWithMargins(ScrollView.java:1217) at android.widget.FrameLayout.onMeasure(FrameLayout.java:310) at android.widget.ScrollView.onMeasure(ScrollView.java:321) at android.view.View.measure(View.java:15848) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:5008) at android.widget.FrameLayout.onMeasure(FrameLayout.java:310) at android.view.View.measure(View.java:15848) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:5008) at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1404) at android.widget.LinearLayout.measureVertical(LinearLayout.java:695) at android.widget.LinearLayout.onMeasure(LinearLayout.java:588) at android.view.View.measure(View.java:15848) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:5008) at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1404) at android.widget.LinearLayout.measureVertical(LinearLayout.java:695) at android.widget.LinearLayout.onMeasure(LinearLayout.java:588) at android.view.View.measure(View.java:15848) 

SECOND UPDATE

the error in question is the second of

 final Drawable d = getDrawable(); final int origW = d.getIntrinsicWidth(); final int origH = d.getIntrinsicHeight(); 

The full code is here when the stack overflows Attempt to get image size in ImageView . This is a majority vote.

Answer 1

Make sure you provide the correct constructor for XML. Your own view designer must have the following method signature:

 public SizeAwareImageView(Context context, AttributeSet attrs){ // todo } 

I assume it currently looks like this:

 public SizeAwareImageView(Context context){ // todo } 

I would also double check that you would like to set the XML parameter android:background , for ImageView you really installed android:src .
