this will help To align item in center with position: 'absolute' you have to add following style

code :

 {
    position: "absolute",
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: "center",
    alignItems: "center"
  }

{ flex: 1 }

import React from "react";
import { View, Text, StyleSheet } from "react-native";

export default class Home1 extends React.Component {
  render() {
    return (
      <View style={styles.mainContainer}>
        <Text style={styles.score}>Score: 50</Text>
        <View style={styles.container}>
          <Text>Animator container</Text>
        </View>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  mainContainer: { flex: 1 },
  container: {
    position: "absolute",
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: "center",
    alignItems: "center"
  },
  score: {
    fontSize: 30,
    alignItems: "center",
    top: 100
  }
});

around this issue I have a view. I want an image logo to appear in the top left of the layout and in the centre of the layout (both horizontally and vertically) I want text with 2 buttons (side-by-side) below the text. Here is what I have and it does not work...any help? , I think this does what you want:

code :

<ImageView
    android:id="@+id/imgLogo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_x="-6px"
    android:layout_y="32px"
    android:background="@drawable/logo" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_centerVertical="true"
    android:gravity="center_vertical"
    android:layout_weight="1"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Welcome to my app. Please select your language"
        android:textColor="#FFFFFF"
        android:textSize="20sp" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/TextView01"
        android:layout_centerInParent="true"
        android:background="@android:drawable/bottom_bar"
        android:gravity="center"
        android:orientation="horizontal"
        android:paddingBottom="1.0dip"
        android:paddingLeft="4.0dip"
        android:paddingRight="4.0dip"
        android:paddingTop="5.0dip" >

        <Button
            android:id="@+id/btnEnglish"
            android:layout_width="0.0dip"
            android:layout_height="fill_parent"
            android:layout_weight="1.0"
            android:text="English" />

        <Button
            android:id="@+id/btnSpanish"
            android:layout_width="0.0dip"
            android:layout_height="fill_parent"
            android:layout_weight="1.0"
            android:text="Spanish" />
    </LinearLayout>

By : 胡博

wish help you to fix your issue you have to set width TableRow to android:layout_width="wrap_content" then make gravity center android:layout_gravity="center"

code :

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:orientation="vertical" >

          <TableRow
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_gravity="center"
              android:paddingBottom="3dip"
              android:paddingLeft="10dip"
              android:paddingRight="10dip"
              android:paddingTop="10dip" >

          <Button
            android:id="@+id/Btn_Show"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 1" />

          <Button
              android:id="@+id/button2"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_gravity="center_horizontal"
              android:text="Button 2" />

         </TableRow>
          <TableRow
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_gravity="center"
              android:paddingBottom="3dip"
              android:paddingLeft="10dip"
              android:paddingRight="10dip"
              android:paddingTop="10dip" >
          <Button
            android:id="@+id/button3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 3" />
          <Button
            android:id="@+id/button4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button 4" />
        </TableRow>

</LinearLayout>
</FrameLayout>

Centre icon and text vertically and horizontally

By : user3051219

Date : March 29 2020, 07:55 AM

this one helps. It's perfectly possible. Remove the float, and use a combination of display: inline-block and vertical-align: middle instead.
Here's the fiddle.

code :

.icon26:before {
    background: url(/assets/images/sprite26.png) no-repeat 0 0;
    content: "";
    display: inline-block; /* <-- instead of float: left */
    vertical-align: middle; /* <-- add to vertically center inline blocks */
    height: 2.6rem;
    width: 2.6rem;
}

#nav ul li {
    float: left;
    width: 33.33%;
    text-align: center; /* <-- add this to horizontally center inline items */
}

How Can I Centre Multiline Text Horizontally and Vertically Using PIL

By : Ondřej Jánský

Date : March 29 2020, 07:55 AM

it should still fix some issue Both the frame and the text are centred around the top left hand corner and each offset is in pixels.
the value W is the width of the frame and H is the height of the frame.
