Question

I have this code , and I want to run Log.d every 1000 milis , but It only run once .

seekView.postDelayed(new Runnable() {

                public void run() {
                    Log.d("WWWW", "www");

                }
            }, 1000);

creating handler , timer , … only run once like this , where is my problem ?

Answer 1

To keep it running continuously at an interval of 1 second, you need to call postDelayed as nested in your Run method again. See the example below:

seekView.postDelayed(new Runnable() {

  public void run() {
    Log.d("WWWW", "www");

    //calling postdelayed again
    seekView.postDelayed(this, 1000);       //added this line
  }
}, 1000);

doing so will keep it calling it self at an interval of 1 second.
