Same button with multiple taps

The idea is that a button can do one thing on the first click and another thing on the second click.

button_food   = (Button) findViewById(R.id.foodicon_layout);
button_travel = (Button) findViewById(R.id.travelicon_layout);
button_fuel   = (Button) findViewById(R.id.fuelicon_layout);
button_fetch  = (Button) findViewById(R.id.fetchicon_layout);

button_travel.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        // Perform action on click
        button_food.setVisibility(View.GONE);
        button_fuel.setVisibility(View.GONE);
        button_fetch.setVisibility(View.GONE);
    }
});

In this example, when the button_travel button is clicked, the other buttons become invisible. on clicking this again, I want the other buttons to be visible again.

You can force the button to set its visibility by getting their current visibility and toggling it.

button_food   = (Button) findViewById(R.id.foodicon_layout);
button_travel = (Button) findViewById(R.id.travelicon_layout);
button_fuel   = (Button) findViewById(R.id.fuelicon_layout);
button_fetch  = (Button) findViewById(R.id.fetchicon_layout);

button_travel.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        int visibility = button_food.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE;

        // Perform action on click
        button_food.setVisibility(visibility);
        button_fuel.setVisibility(visibility);
        button_fetch.setVisibility(visibility);
    }
});


Writing this type is just a simple way to write an if statement

int visibility;
if(button_food.getVisibility() == View.VISIBLE){
     visibility = View.GONE;
} else {
     visibility = View.VISIBLE;
}

Just check the current state and act accordingly.



public void onClick(View v) {

    // Perform action on click
    if (button_food.getVisibility() == View.VISIBLE) {
        button_food.setVisibility(View.GONE);
    } else {
        button_food.setVisibility(View.VISIBLE
    }

    if (button_fuel.getVisibility() == View.VISIBLE) {
        button_fuel.setVisibility(View.GONE);
    } else {
        button_fuel.setVisibility(View.VISIBLE
    }

    if (button_fetch.getVisibility() == View.VISIBLE) {
        button_fetch.setVisibility(View.GONE);
    } else {
        button_fetch.setVisibility(View.VISIBLE
    }
}

Are you looking for this ?:

public void onClick(View v) {

             if(visible){
                    visible=false;
                    button_food.setVisibility(View.GONE);
                    button_fuel.setVisibility(View.GONE);
                    button_fetch.setVisibility(View.GONE);
             }else{ 
                    visible=true;
                    button_food.setVisibility(View.VISIBLE);
                    button_fuel.setVisibility(View.VISIBLE);
                    button_fetch.setVisibility(View.VISIBLE);
            }
    }

what you can do is check their visibility if they are visible that set visiblity for go else added visisiblity in Visible for reference, see below code

  if (button_food.getVisibility()==View.VISIBLE) {
  button_food.setVisibility(View.GONE);
    } else {
         button_food.setVisibility(View.VISIBLE);
    }

if (button_fuel.getVisibility()==View.VISIBLE) {
  button_fuel.setVisibility(View.GONE);
    } else {
         button_fuel.setVisibility(View.VISIBLE);
    }

 if (button_fetch.getVisibility()==View.VISIBLE) {
         button_fetch.setVisibility(View.GONE);
    } else {
         button_fetch.setVisibility(View.VISIBLE);
    }

If you are using an array I think it is too simple

Button btnArray[] = new Button[4];

    btnArray[0] = (Button) findViewById(R.id.button_food);
    btnArray[1] = (Button) findViewById(R.id.button_travel);
    btnArray[2] = (Button) findViewById(R.id.button_fuel);
    btnArray[3] = (Button) findViewById(R.id.button_fetch);


    View.OnClickListener btnListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            for (int i = 0; i < btnArray.length; i++) {
                if (btnArray[i].getId() != v.getId())
                    if (btnArray[i].getVisibility() == View.GONE)
                        btnArray[i].setVisibility(View.VISIBLE);
                    else
                        btnArray[i].setVisibility(View.GONE);
            }
        }
    };
    for (int i = 0; i < btnArray.length; i++)
        btnArray[i].setOnClickListener(btnListener);

I think this is the cleanest way:

button_food   = (Button) findViewById(R.id.foodicon_layout);
button_travel = (Button) findViewById(R.id.travelicon_layout);
button_fuel   = (Button) findViewById(R.id.fuelicon_layout);
button_fetch  = (Button) findViewById(R.id.fetchicon_layout);
private boolean visible;

button_travel.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        if(visible){
            visible=false;
            button_food.setVisibility(View.GONE);
            button_fuel.setVisibility(View.GONE);
            button_fetch.setVisibility(View.GONE);
        }else{ 
            visible=true;
            button_food.setVisibility(View.VISIBLE);
            button_fuel.setVisibility(View.VISIBLE);
            button_fetch.setVisibility(View.VISIBLE);
        }
    }
});
