copied!<p>You can create a timer and then hide the dialog like this:</p> <pre><code>Timer tShow = new Timer(); Timer tHide = new Timer(); // This timer will show the popup every 10 second tShow.schedule(new TimerTask(){ public void run(){ helpDialog.show(); Date d = new Date(); d.setSeconds(d.getSeconds()+20); //This will hide the popup after 20 secnds tHide.schedule(new TimerTask(){ public void run(){ helpDialog.dismiss(); } },d); } },0,10*1000); </code></pre> <p>Declare Timers and Dialog as variables of class. But, i dont understand that if you show popup every 10sec and hide every 20sec how is it going to work?</p> <p><strong>EDIT</strong></p> <pre><code>private Timer tShow = new Timer(); private Timer tHide = new Timer(); private AlertDialog helpDialog; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); AlertDialog.Builder helpBuilder = new AlertDialog.Builder(MainActivity.this); helpBuilder.setTitle("Pop Up"); helpBuilder.setMessage("This is a Simple Pop Up"); helpBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // Do nothing but close the dialog } }); helpBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // Do nothing } }); helpBuilder.setNeutralButton("Neutral", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // Do nothing } }); helpDialog = helpBuilder.create(); // This timer will show the popup every 10 second tShow.schedule(new TimerTask(){ @Override public void run(){ abc(); } },0,10*1000); } public void abc(){ this.runOnUiThread(my_Function); } private Runnable my_Function = new Runnable() { @Override public void run() { helpDialog.show(); Date d = new Date(); d.setSeconds(d.getSeconds()+20); //This will hide the popup after 20 secnds tHide.schedule(new TimerTask(){ public void run(){ helpDialog.dismiss(); } },d); } }; @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } </code></pre>
