How to set transparent background for Image Button in code?

Question

I can set ImageButton background transparent in layout.xml using:

android:background=\"@android:color/transparent\"

How I can

Answer 1

This should work - imageButton.setBackgroundColor(android.R.color.transparent);

Answer 2

Try like this

ImageButton imagetrans=(ImageButton)findViewById(R.id.ImagevieID);

imagetrans.setBackgroundColor(Color.TRANSPARENT);

OR

include this in your .xml file in res/layout

android:background="@android:color/transparent 

Answer 3

DON'T USE A TRANSAPENT OR NULL LAYOUT because then the button (or the generic view) will no more highlight at click!!!

I had the same problem and finally I found the correct attribute from Android API to solve the problem. It can apply to any view

Use this in the button specifications

android:background="?android:selectableItemBackground"

This requires API 11

Answer 4

This is the simple only you have to set background color as transparent

    ImageButton btn=(ImageButton)findViewById(R.id.ImageButton01);
    btn.setBackgroundColor(Color.TRANSPARENT);

Answer 5

simply use this in your imagebutton layout

android:background="@null"

using

 android:background="@android:color/transparent 

or

 btn.setBackgroundColor(Color.TRANSPARENT);

doesn't give perfect transparency

Answer 6

If you want to use android R class

textView.setBackgroundColor(ContextCompat.getColor(getActivity(), android.R.color.transparent));

and don't forget to add support library to Gradle file

compile 'com.android.support:support-v4:23.3.0'
