Single touch in ANDROID

Question

Is it possible to allow the user to touch the screen only once?

Meaning: A user touches the screen and if he tries to touch the screen again nothing will happen. I am implementing the approach using canvas to draw the objects on the screen.

Thank you in advance!

Declare one global boolean variable and use this as your requirement — Piyush, Dec 17 '13 at 11:36
@Naddy I am clicking on an element that i drew(lest say rectangle). It draws the new elements and after the drawing i want to prevent the user to click again. — chikito1990, Dec 17 '13 at 11:50
Add a `boolean` flag as mentioned above. When the user clicks on your `rectangle` just change the `boolean` flag to `false`. Do the clicking part only when your flag is `true`. — Naddy, Dec 17 '13 at 11:58
I used boolean variable so some of the above mentioned comments to be converted into an answer so i can accept it :) — chikito1990, Dec 17 '13 at 12:37

From what you have in mind, setClickable() or onTouchEvent would be the best way to go.

Have a look on this reference:

As commented above - use a boolean variable as a flag and toggle it between true and false according to how the user interacts!
