disable button in listener for 1s and generate an output stream after that in android

Question

I'm new in stackoverflow. I created a simple bluetooth app to controll a relay board.

The Relay is "on" for 1s after clicking the a button. It works so far but if I click the button during the 1s the relay gets "on" for another 1s.

So I want to disable the button while the relay is "on". I used .postDelayed(). This works as well, but it is not possible to generate the outputStream to clear the relay in the .postDelayed() routine.

Does anybody have an idea for me?

regards Joe

// Rel1 btn click
        mRel1Btn.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View view) {

                    mRel1Btn.setEnabled(false);
                    mRel1Btn.setClickable(false);

                        if (mBlueAdapter.isEnabled()) {

                            try {
                                OutputStream mOutputStream = mBtSocket.getOutputStream();
                                mOutputStream.write(RELAY_ON);

                                new Handler().postDelayed(new Runnable()
                                                          {
                                                              public void run()
                                                              {
                                                                  mRel1Btn.setEnabled(true);
                                                                  mRel1Btn.setClickable(true);
                                                                  mOutputStream.write(RELAY_OFF);  // sending bytes to serial COM (BT)
                                                                  
                                                              }
                                                          }, 1000    //Specific time in milliseconds
                                );
                            } catch (IOException e) {
                                e.printStackTrace();
                            }
                        }
            }
        });

Following error occured

error: unreported exception IOException; must be caught or declared to be thrown

mOutputStream.write(RELAY_OFF); (marker on opening brace)

Solved:

I created a subroutine "sendMessage(message)" and called this subroutine out of my listener.

// Rel1 btn click
        mRel1Btn.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View view) {
                    if (mBlueAdapter.isEnabled()) {

                        sendMessage(RELAY1_JDY30_ON);
                        mRel1Btn.setEnabled(false);
                        mRel1Btn.setClickable(false);

                        new Handler().postDelayed(new Runnable()
                                                  {
                                                      public void run()
                                                      {
                                                          sendMessage(RELAY1_JDY30_OFF);
                                                          mRel1Btn.setEnabled(true);
                                                          mRel1Btn.setClickable(true);
                                                      }
                                                  }, 1000    //Specific time in milliseconds
                        );
                    }
            }
        });

    private void sendMessage(byte[] message) {
        OutputStream mOutputStream;
        try {
            mOutputStream = mBtSocket.getOutputStream();
            mOutputStream.write(message);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
