first click change to new image and second click change to old image, android
<p>this application requires:
first click will change image1 to image2
second click will change back to old image (image2 to image1)</p>

<pre><code>image1  = (ImageView)findViewById(R.id.imageView1);
        image1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                image1.setImageResource(R.drawable.a3_01);
                image1.setTag(70);              
            }
        });
</code></pre>
