copied!<p>In my app i have a ListView which dynamically increases by adding 10 items everytime on scrolling down. when i click on any item it takes me to a google-map, and to get back to the listView i have a button.</p> <pre><code> public void onClick(View arg0) { Intent intent = new Intent(MapMarkerActivity.this, FeedListViewActivity.class); startActivity(intent); } </code></pre> <p>but my FeedListViewActivity takes some 3-4 secs to load , so during this time if i click the back button on my device the screen flashes for some 0.3 sec and show the google-map(essentially its not going anywhere). now i click the back button on my device it gives me a blank screen and when i click the back button second time it takes me to the listView. the problem is here...now when i try to scroll the listview my app crashes saying:</p> <p>IndexOutOfBounf index=30 size=10;</p> <p>so i changed my onclick to:</p> <pre><code> public void onClick(View arg0) { finish(); } </code></pre> <p>now on clicking this button it gives me a blank screen and then i must click the back button of my device to get to the listview from the google-map.</p> <p>My question is why am i getting that blank screen... I mean why should i click twice back to get back to the listview and why am i getting the indexOutOfBound exception.</p> <p>The reason i named the question this way is "i want that back button on my device to be blocked when i click on the button(in my app) to go back to the listview which has a 3-4 sec delay"</p>
