ListView only appears when I click to close the keyboard [closed]

I do not know how to solve this problem, but the list-view does not appear when I search, it only comes to appear when I click the button to close the keyboard, it seems that when I press the button it updates the Activity and there it appears a lot strange.

Below are images with the problem.
