Solution 1 - Android
This is the simple only you have to set background color as transparent
ImageButton btn=(ImageButton)findViewById(R.id.ImageButton01);
btn.setBackgroundColor(Color.TRANSPARENT);
Solution 2 - Android
Do it in your xml
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageButtonSettings"
android:layout_gravity="right|bottom"
android:src="@drawable/tabbar_settings_icon"
android:background="@android:color/transparent"/>
Solution 3 - Android
This should work - imageButton.setBackgroundColor(android.R.color.transparent);
Solution 4 - Android
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
Solution 5 - Android
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
Solution 6 - Android
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
Solution 7 - Android
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'
