setting android button invisible but still having an onClick Listener attached

Question

So currently I\'m putting an Easter egg inside my app and I want the Button to be invisible, but when clicked(Rick roll). So far I can make it work when I say:

Answer 1

try making the text in the button " "...

myButton.setText("    ");

Answer 2

You can also disable the button (It will not be clickable).

In java code:

btn.setClickable(false);

In .xml layout:

android:clickable="false"

Answer 3

You can add an OnClickListener to any View, so try creating an ImageView with a transparent image and attach your listener to that.

Answer 4

You can create any view, such as LinearLayout, as clickable. Make a LinearLayout with the same dimensions as the button and set it's onClick listener to whatever handles the event. Since it inherently isn't visible, it should hold the same effect.

Answer 5

In your layout, make your button have a specific width, like android:layout_width="40dp".

If your width is set to wrap_content with a transparent background and no text, Android will measure that view as having a width of 0dp. You'll never be able to click on that.

Answer 6

This works properly for me:

• btn.setClickable(false) on GONE visibility.
• btn.setClickable(true) on VISIBLE visibility.
