Android: How to solve slow response after clicking TabWidget
<p>I have four Tab at the top of my apps<br>
The content of the fourth tab is that it will get data from sql server and then display in listview<br>
since the amount of data retrieved is quite big, it takes 2-3 sec<br>
The problem is that:<br>
After I click the fourth tab, it has no response, then after 2-3sec, it displays the content<br>
As I know it is loading the data from database, I will not continue to click<br>
However, when users click it and no response, he may click and click and click<br>
How to show something to user so that they know it is loading data??</p>
