如何在线性布局中居中文本视图 [英] How to center a textview inside a linearlayout

问题描述

我有以下布局，我想让 textview 出现在视图的中心和中间.我怎样才能做到这一点?

I have the following layout i'd like to make the textview appear in the center and middle of the view. How can i acheive this?

在图形视图中查看布局时，我尝试调整各种重力属性，但似乎没有任何改变.我想要中间的 textview，我已经完成了但在视图的一半.

I've tried adjusting the various gravity attributes when looking at the layout in graphical view, but nothing seems to change it. I'd like the textview in the center which i've done but halfway down the view.

谢谢马特.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/carefreebgscaledalphajpg" >



    <TextView
        android:id="@+id/textviewdatefornocallspage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="You have no calls for "
        android:textSize="25sp" />

</LinearLayout>

推荐答案

在你的 linearLayout 标签中将重力设置为中心:

set the gravity to center in your linearLayout tag :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
     android:gravity="center"
    android:background="@drawable/carefreebgscaledalphajpg" >

或者像这样使用 RelativeLayout :

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



    <TextView
        android:id="@+id/textviewdatefornocallspage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="You have no calls for "
        android:textSize="25sp" />

</RelativeLayout>
