public int[] object = new int[] { R.drawable.line1,R.drawable.line2}; 
//line1,2 is image line1.png and line2.png

Button button1 = (Button)findViewById(R.id.button1);
        button1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                imgView .setVisibility(View.VISIBLE);
            }
        });
Button button2 = (Button)findViewById(R.id.button2);
            button2.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    imgView .setVisibility(View.INVISIBLE);
                }
            });
