Click button action in android?

I have two buttons in Android. Btn1 and Btn2. I need to show Btn1 by default, and when I click, I need to show Btn2 instead of Btn1. Again, when Btn2 is clicked, it should be replaced by Btn2. Please help me with some example ..

My code is:

btn1 = (ImageView) findViewById(R.id.firstbtn);

        btn2 = (ImageView) findViewById(R.id.secondbutton);
        btn2.setVisibility(ImageView.GONE);

        btn1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                btn2.setVisibility(ImageView.VISIBLE);
            }
        });

        btn2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                btn2.setVisibility(ImageView.GONE);




            }

        });

Thanks in advance

You can use the same button and change its label as an alternative, and by level you can put a check and do the corresponding work.

In accordance with your updated code, find out that you are using ImageView, try this

   ImageView btn = (ImageView) findViewById(R.id.secondbutton);
    btn.setTag("1");//can use one empty String "" and null instead of "1" and "2" for optimization

        btn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                Object obj = v.getTag();

                if(obj instanceof String){
                     if("1".equals(obj)){
                         v.setTag("2");
                         //Your first button state 
                     }else if("2".equals(obj)){
                         v.setTag("1");
                         //Your second button state 
                     }

                }

...

If your case is defined for two buttons, you can use two string comparison operations

ImageView btn = (ImageView) findViewById(R.id.secondbutton);
  btn.setTag(null);

    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            if(v.getTag() instanceof String){
                     v.setTag(null);
                     //Your first button state 
            } else {
                      v.setTag("");
                     //Your second button state 
            }

If you want your code to work correctly

btn1 = (ImageView) findViewById(R.id.firstbtn);

        btn2 = (ImageView) findViewById(R.id.secondbutton);
        btn2.setVisibility(ImageView.GONE);

        btn1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                v.setVisibility(ImageView.GONE);
                btn2.setVisibility(ImageView.VISIBLE);

            }
        });

        btn2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                v.setVisibility(ImageView.GONE);
                btn1.setVisibility(ImageView.VISIBLE);

            }

        });

        @Override
        public void onClick(View v) {
            btn1.setVisibility(View.GONE);
            btn2.setVisibility(View.VISIBLE);
        }
    });

You can create two buttons in the layout with the same exact positions, then you can set the visibility and action of each button that you want

You can use the visible () method to capture its visibility. A ToggleButton or one button and switching text to a click event should work better than two buttons.
