Question

How do I display ImageView in Android every 1 second, then hide it for 1 sec and display it again for 1 sec, repeating indefinitely? I tried using the below technique. I am just a newbie.

ImageView v=(ImageView)findViewbyID(R.id.mypic);
Date d=new Date();
SimpleDateFormat sdf=new SimpleDateFormat("ss");
if(sdf.format(d)%2==0)
    v.setVisibility(View.INVISIBLE); 

The above code just makes the image invisible and does not run continuously.

Answer 1

public Void Handle {
    new Handler().postDelayed(new Runnable() {
    boolean visible = true;
       public void run() {
      final ImageView v = (ImageView)findViewById(R.id.mypic);

      if(visible)
           v.setVisibility(View.INVISIBLE); 
       else
           v.setVisibility(View.VISIBLE); 

              }
  }, 100);

      Handle();
}
