Remove background drawable programmatically in And

Question

I want to remove the background drawable (@drawable/bg) programmatically. Is there a way to do that?

Currently, I have the following XML in my layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/widget29"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@drawable/bg">

</RelativeLayout>

Answer 1

I have a case scenario and I tried all the answers from above, but always new image was created on top of the old one. The solution that worked for me is:

imageView.setImageResource(R.drawable.image);

Answer 2

This work for me:

yourview.setBackground(null);

Answer 3

setBackgroundResource(0) is the best option. From the documentation:

Set the background to a given resource. The resource should refer to a Drawable object or 0 to remove the background.

It works everywhere, because it's since API 1.

setBackground was added much later, in API 16, so it will not work if your minSdkVersion is lower than 16.

Answer 4

First, you have to write

 android:visibility="invisible" <!--or set VISIBLE-->

then use this to show it

 myimage.setVisibility(SHOW);//HIDE                                       

Answer 5

Try this code:

imgView.setImageResource(android.R.color.transparent); 

also this one works:

imgView.setImageResource(0); 

but be careful this one doesn't work:

imgView.setImageResource(null);
