@alextsc I want to remove background of Button(and want to set default background) not of image-button .and if I try to set null or transparent image in background of Button then Button becomes disappears.why?????? — Atul Bhardwaj, Jul 13 '12 at 13:13
@AtulBhardwaj The code is the same for both the ImageButton and the Button widget *(which you would have know if you tried before asking)*. Also you should reword your question, I misunderstood it *(along other people apparently)*. I was under the impression that you wanted to remove any background, including the default one, not that you wanted to reset a custom background to default. — , Jul 13 '12 at 13:19

You can use android:background="@null" for your Button.
or button.setBackgroundResource(0);
or button.setBackgroundDrawable(null);

button.setBackgroundResources(0); This is giving error as this method is undefined for button. and button.setBackgroundDrawable(null); makes my button disappear. – Atul Bhardwaj Jul 13 '12 at 13:19

By programatically, you can do something like,

button.setBackgroundDrawable(null);
button.setBackgroundResource(0);

Finally I got solution of my problem btn.setBackgroundDrawable(getResources().getDrawable(android.R.drawable.btn_default)); This makes my button's background as it has by default.

One solution is simply to remember which Drawable you had as the background before you set it to a custom one, e.g. save it in onCreate().

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_layout);

    button = (Button) findViewById(R.id.yourbutton);
    defaultButtonBackgroundDrawable = button.getBackground();

    // set a custom background here, or somewhere else. 
    // Just make sure that the default one is saved before you modify it.
}

where defaultButtonBackgroundDrawable is a member variable of your activity and button keeps a reference to your button. This way you can restore the default background pretty easily by doing

button.setBackgroundDrawable(defaultButtonBackgroundDrawable);

thanks for this solution.It works fine for me But I found one other solution that also works btn.setBackgroundDrawable(getResources().getDrawable(android.R.drawable.btn_default)); — Atul Bhardwaj, Jul 13 '12 at 13:41
