Navigation bar 48dp on every screen

Question

I'm trying to make an android app. But I'm having many troubles with the design. I want to make a navigaton bar with a height of 48 dp on every screen. I know which height in px I have to use but I don't understand which width because every screen has another and it dosen't scale right. I just want a navigaton bar in one color with a height of 48dp and a witdh which scales to the screen so that it is from the left all way to the right with a continious height of 48dp. I hope you understand my problem if not please ask. Thanks for your time!

Answer 1

The accepted answer is deprecated. Please use match_parent instead of fill_parent

Answer 2

There is one more attribute

android:gravity="fill_horizontal"

(Grow the horizontal size of the object if needed so it completely fills its container.)

FOR HELP

Answer 3

Try using android:layout_width="fill_parent".
