    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    button = (Button) findViewById(R.id.button);
    button1 = (Button) findViewById(R.id.button2);
    button2 = (Button) findViewById(R.id.button3);
    button3 = (Button) findViewById(R.id.button4);

    if(button.isClickable()) {


        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                button.setEnabled(false);
                button.setBackgroundColor(Color.RED);
                button1.setEnabled(false);
                button2.setEnabled(false);
                button3.setEnabled(false);
            }
        });
    }
    if(button1.isClickable()) {


        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                button.setEnabled(false);
                button1.setBackgroundColor(Color.RED);
                button1.setEnabled(false);
                button2.setEnabled(false);
                button3.setEnabled(false);
            }
        });
    }
    if(button2.isClickable()) {


        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                button.setEnabled(false);
                button2.setBackgroundColor(Color.RED);
                button1.setEnabled(false);
                button2.setEnabled(false);
                button3.setEnabled(false);
            }
        });
    }
    if(button3.isClickable()) {


        button3.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                button.setEnabled(false);
                button3.setBackgroundColor(Color.RED);
                button1.setEnabled(false);
                button2.setEnabled(false);
                button3.setEnabled(false);
            }
        });
    }
    Log.e("onCreate: ", "UniqueKey: " + getUniqueKey());

Save the state of the button in SharedPreferences , and when reopening the application again, check the value inside preferences and load the layout.

There is an option called SharedPreferences in Android which allows you to save the instance of any state of your App to the memory and then to retrieve it from the settings. So just save the button ID to the SharedPreferences and when you open the application get the ID of the button in the preference and then disable the other buttons you need i be disabled.

Shared Preference Example

1.store value in sharedPrefernces:

SharedPreferences preferences = this.getSharedPreferences("SoldiPreferences", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean("storevalue", false);
editor.commit();

2.get value from sharedPreferences: In Oncreate of your Activity

   SharedPreferences preferences = this.getSharedPreferences("SoldiPreferences", Context.MODE_PRIVATE);
    preferences.getBoolean("storevalue", false);

    if(preferences.getBoolean("storevalue", false))
    {
    button.setclickable(true);
   button.setenable(true);
    }
    else{
     button.setclickable(false);
   button.setenable(false);
}

onButtonCLikListner update sharefpreffernce value

final Button button=new Button(this); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {

            SharedPreferences preferences = getApplicationContext().getSharedPreferences("SoldiPreferences", Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = preferences.edit();

            if(preferences.getBoolean("storevalue", false))
            {


                editor.putBoolean("storevalue", false);
                editor.commit();
            }
            else{

                editor.putBoolean("storevalue", true);
                editor.commit();
            }

            button.setclickable(true);
            button.setenable(true);



        }
    });
