Answer 1

You have given your TextView width wrap_content, and that is the problem, Check below code and replace it to your code.

<TextView
android:id="@+id/txtInvalid"
android:layout_width="match_parent"   
android:layout_height="wrap_content"
android:text="@string/invalid"
android:gravity="center"   
/>

Answer 2

set android:layout_width="fill_parent" for textView1

Answer 3

You set this text view a width of "wrap_content" it means, what ever the text is, the view take the size of the text.

and in the LinearLayout , the default gravity (used here) is 'center'

you should try this :

<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"   <= change this
android:layout_height="wrap_content"
android:text="@string/invalid"
android:gravity="center"   <= then this gravity will be taken into account
/>

Answer 4

Make sure you don't have something like that hanging around

app:layout_box="left|top"

Answer 5

99% of the time, not working properly == not used properly.

You are mistaking gravity and layout_gravity.

gravity is the way the text will align itself in the TextView. The TextView being in wrap_content this does nothing, as the TextView is exactly the size of the text.

layout_gravity is the way the TextView will align itself in its parent, in your case in the vertical LinearLayout
