You can use an Boolean Variable for prevanting to run your code on every button click as:

boolean isClicked=true;
Button btn = (Button) findViewById(YourId);
btn.setonClickListener(listener);
public onClickListener listener = new View.OnclickListener{
      onclick(View v){
      if(isClicked==true)
      {
        isClicked=false;
        doWork();
        //DO YOUR WORK HERE...
      }
      else
      {
        // DO NOTHING...
      }
      }
}
 public void doWork(){
      /// YOUR CODE HERE...

         //USE AsyncTask ,Hanlder,handlerThread, or Thread for performing long running         task in background on button click
        isClicked=true;


     }

Are you calling a web service after the button is tapped ? There are several options:

1.Add a progress dialog that will disable anything in the background.If it is a web service this is the best solution.

2.Disable any UI element in the screen for the time period that you are performing any action.

3.Spawn a new thread or an async task.
