Why is the button compacted or off-screen in Android Studio?

You know I have a question about why I have the "Add" button that way, it is practically as if it were leaving the activity, even the text "Add data ..." is also wrong because of this, I have to say that I'm still new to all this from the android studio, so anything could help me, I tried a lot but I couldn't fully show the button, only the part that you see in the image (I tried using LinearLayout as well)

it's done like that

this is how I would like it to look

I add the xml code
