阅读更多关于 How do I close a SearchView programmatically?

I currently have a SearchView in the action bar of my app. When I click the search icon, the SearchView expands and the keyboard pops up as expected. Clicking the "X" in the SearchView box closes the SearchView as expected. However, when the SearchView is activated and I press the "back" button, my app is exited. This is the correct behavior, but what I am trying to do now is to capture back button press and just have it close the SearchView (not my app) when the SearchView is visible.

Can you help me on how to disable searchview when button is pressed? I'm trying this code: searchView.setEnabled(false); searchView.setFocusableInTouchMode(false); searchView.clearFocus(); but it seems not working. I can still input text in searchview.
