Problems with layout of a list

I'm doing an app on android. It is a Quiz style application with only one correct answer. I have this layout in question but what happens is that I overlap the answers. Those that are long are not seen at all and are covered by the following options. How can I leave the necessary space between answers so they do not overlap?

I also try to put the TextViewQuestion justified to make it more aesthetic but I do not get it.

Finally the last ImageView (chek) I would like to put it right at the end of the possible answer, that is, before the layout of a question ends but it is covered by the next question and it is not seen. Thank you very much!
