TextView in the center of the screen [duplicate]

How do I center text horizontally and vertical in a TextView in Android?

I have a RelativeLayout (before it was a LinerLayout), that occupies all the screen and I want to put in the center of this Layout, a TextView. I try to do it with gravity = "center" layout_gravity = "center" and a few more, but it doesn't work.

Anybody knows how to center the TextView in the middle of the screen?

EDIT

Ok, I think I explained badly. I think the TextView is in the center, but what I want to center is the text in the TextView. Can I do this?

回答1:

If your font size is big enough, it might look like it's not centered, because of the font padding.
Try using the already mentioned properties combined with android:includeFontPadding, something like this:

    android:gravity="center"
    android:includeFontPadding="false"

If you want to align contents of RelativeLayout in the center then you need to put android:gravity="center" in the RelativeLayout's properties. Below is a sample XML code for it along with its visual representation.

XML Code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:background="@color/white">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="My Text View"
            android:textColor="@color/black"
            android:textSize="25dp"
            android:textStyle="bold" />
</RelativeLayout>

Graphical Layout:

Try android:layout_centerInParent="true" or android:layout_centerHorizontal="true" these apply to RelativeLayout

回答4:

You can also set the gravity="center" of its parent.

Alternatively, taken from another post

<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center_vertical|center_horizontal"
    android:text="@string/**yourtextstring**" />

回答6:

android:gravity="center"

works on RelativeLayouts only. So try

<TextView
        android:id="@+id/title"
        android:layout_width="fill_parent" <!--relative Layout-->
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Mint Payments"/>

This should display in center of the screen with center aligned. If you want to text alignment, you may use android:gravity="right" or android:gravity="left"

     <RelativeLayout
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:orientation="horizontal">

                <TextView
                    android:id="@+id/textView"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerInParent="true"
                    android:gravity="center" 
                    android:text="This is some text" />    
    </RelativeLayout>

    <RelativeLayout
    android:gravity="center"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >
     <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Txt is aligned in Center" />
   </RelativeLayout>
