import android.widget.TextView;

public class MyappActivity extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {

    Button btn=(Button) findViewById(R.id.enter);
    btn.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            String prepwd="password";
            EditText  et=(EditText) findViewById(R.id.pwd);
                ImageView iv=(ImageView) findViewById(R.id.im1);

How to&Answers:

You can modify the visibility of a view with view.setVisibility(x);, where x is View.INVISIBLE, View.VISIBLE, or View.GONE.

You should probably define the image as invisible in your layout XML… android:visibility="invisible"

You can’t set visibility on ImageView as your code shows, you must findViewById() to get the view to set visibility on. You seem to be doing that with your iv variable already, so just call the setVisibility() method on it.
