we have an android app that lets you share thoughts with friends without revealing who you are. It's in developing processes now! I designed comments delete screen, but I'm not sure it's good for UX. What do you think about?
The major issue here is I don't know how to answer the question about deletion. You've asked the question in plain English, but I assume you are expecting me to answer in symbolic form. Do I click the 'trash symbol' to delete the message? It would be much clearer if the symbol was appended with the words "Yes, delete this comment". How do I cancel? There's no button to do that.
Also, you should perhaps place the comment under the question, and place the buttons last. Using the word "this" in your question is referring to something that is 2 objects away. Whenever you use the word "this", the object to which you are referring to should be adjacent to the sentence.
The final word on confirmation dialogs is given in the article Never use a warning when you mean undo by Aza Raskin on A List Apart. Here's the key idea:
The undo option actually eliminates the risk, instead of providing false safety and annoying users.
I like your design, but in my opinion it seems a little dangerous to place an invitation to delete content above the content itself. There are exceptions to this rule but generally I think it would be safer to place it beneath.
Further to Brendon's answer, I think you could condense this further to just the one button: the word "Delete", with the trash icon to the left / above it. It's maybe just me, but I would be comfortable just tapping in the greyed out area to cancel / go back.
