problem with using button.setPressed(false); in android java code

I want to disable the button press on a 2nd click, so I have this code for the action handler of the button in my android code :

      //开发者_开发知识库 do something when the button is clicked

       public void onClick(View v) {

        final Button button = (Button)findViewById(R.id.radio_red);

        if(button.isPressed()==true && rt1==true ) 

        {

            button.setPressed(false);

            button.clearFocus();

            //rt1=false;

                    //do some processing !     

        }

        else rt1=true;

    }'

However, button.setPressed(false); doesnt work as expected. :(

Can anyone please help me out ?

button.setChecked(false);

this is the line that un-checks the radio button !!!

thanks to everyone who tried to help. :)

I think you want to replace the entire code with button.setClickable(false) - that way, your onClick() handler will be called the first time it is clicked, but any subsequent click won't do anything.

Personally, I think it's better UI design if you call button.setEnabled(false) - that makes it obvious to the user that the button cannot be pressed.
