Centering matter inside a TextView is a communal styling demand successful Android improvement. Whether or not you’re crafting a fastener, designing a rubric, oregon arranging components inside a analyzable format, reaching clean matter alignment is important for a polished person interface. This seemingly elemental project tin typically beryllium difficult, particularly once dealing with some horizontal and vertical alignment concurrently. This usher supplies a blanket breakdown of the strategies you tin usage to halfway matter horizontally and vertically inside a TextView, overlaying assorted eventualities and champion practices.
Utilizing Gravity for Matter Alignment
The android:gravity
property is the about simple manner to power matter alignment inside a TextView. This property permits you to specify however the matter ought to beryllium positioned inside its bounds. For centering some horizontally and vertically, usage “halfway”.
Illustration:
<TextView<br></br> android:layout_width="match_parent"<br></br> android:layout_height="match_parent"<br></br> android:gravity="halfway"<br></br> android:matter="Centered Matter" />
This attack is perfect for elemental circumstances wherever the TextView occupies a mounted measurement inside its genitor structure. The gravity
property impacts the alignment of the matter inside the TextView’s boundaries.
Centering inside a LinearLayout
Once utilizing a LinearLayout, you tin leverage its alignment properties to halfway a TextView. By mounting the android:layout_gravity
property of the TextView to “halfway”, you tin halfway it some horizontally and vertically inside the LinearLayout.
Illustration:
<LinearLayout<br></br> android:layout_width="match_parent"<br></br> android:layout_height="match_parent"<br></br> android:predisposition="vertical"<br></br> android:gravity="halfway"><br></br> <TextView<br></br> android:layout_width="wrap_content"<br></br> android:layout_height="wrap_content"<br></br> android:matter="Centered Matter" /><br></br> </LinearLayout>
Line the discrimination: android:gravity
controls the matter alignment wrong the TextView, piece android:layout_gravity
controls the TextView’s alignment inside its genitor format.
Centering with RelativeLayout
RelativeLayout affords much flexibility successful positioning parts. To halfway a TextView, you tin usage the android:layout_centerInParent
property fit to “actual”.
Illustration:
<RelativeLayout<br></br> android:layout_width="match_parent"<br></br> android:layout_height="match_parent"><br></br> <TextView<br></br> android:layout_width="wrap_content"<br></br> android:layout_height="wrap_content"<br></br> android:layout_centerInParent="actual"<br></br> android:matter="Centered Matter" /><br></br> </RelativeLayout>
This attack is particularly utile for analyzable layouts wherever you demand to assumption the TextView comparative to another components.
Precocious Strategies: ConstraintLayout
ConstraintLayout gives a almighty and versatile manner to make analyzable layouts. Centering a TextView is easy achieved by constraining it to the halfway of the genitor structure.
Illustration:
<androidx.constraintlayout.widget.ConstraintLayout<br></br> android:layout_width="match_parent"<br></br> android:layout_height="match_parent"><br></br> <TextView<br></br> android:layout_width="wrap_content"<br></br> android:layout_height="wrap_content"<br></br> app:layout_constraintBottom_toBottomOf="genitor"<br></br> app:layout_constraintEnd_toEndOf="genitor"<br></br> app:layout_constraintStart_toStartOf="genitor"<br></br> app:layout_constraintTop_toTopOf="genitor"<br></br> android:matter="Centered Matter" /><br></br> </androidx.constraintlayout.widget.ConstraintLayout>
ConstraintLayout permits for exact power complete positioning and provides fantabulous show, making it a most well-liked prime for analyzable UIs. See utilizing ConstraintLayout for its flexibility and ratio, peculiarly successful dynamic layouts.

FAQ
Q: What’s the quality betwixt gravity
and layout_gravity
?
A: gravity
controls the alignment of the contented wrong a position (similar matter successful a TextView), piece layout_gravity
controls however the position itself is positioned inside its genitor structure.
Question & Answer :
However bash I halfway the matter horizontally and vertically successful a TextView
, truthful that it seems precisely successful the mediate of the TextView
successful Android
?
I’m assuming you’re utilizing XML structure.
<TextView android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="halfway" android:matter="@drawstring/**yourtextstring**" />
You tin besides usage gravity center_vertical
oregon center_horizontal
in accordance to your demand.
Arsenic @stealthcopter commented, successful java: .setGravity(Gravity.Halfway);
.
And for Kotlin customers, .gravity = Gravity.Halfway
