Cannot set the background colour of image view when it don't have an image resource
android, android-imageview, setbackground
Solution
The reason you are not seeing anything is because you have the layout_height set to wrap_content. When you do not have an image set on the ImageView wrap_content sets the height to 0. If you want the color to display without an image you will have to set the layout_height to an actual value such as 50dp.
Problem
I want set a background colour to an ImageView, when the imageview has an image resource, it works and i get my background colour but when the image view don't have an image resource, SetBackgroundColor don't work and do nothing, this is my code : xml Layout : ``` <ImageView android:layout_centerHorizontal="true" android:id="@+id/favor_item_image" android:layout_alignParentTop="true" android:layout_height="wrap_content" android:layout_width="match_parent" android:adjustViewBounds="true"/> ``` java code : ``` ImageView favorImage = (ImageView) MyView.findViewById(R.id.favor_item_image); //favorImage.setImageResource(R.drawable.btndelete); favorImage.setBackgroundColor(Color.argb(255,255,0,0)); ``` So, when i comment this line : //favorImage.setImageResource(R.drawable.btndelete); i cannot set the image view background colour , but when i uncomment this line, setBackgroundColor works fine. any help please. Thanks
