Question

I have a simple layout like below (which only shows a text “TEST”):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#ffffff"
>    
    <LinearLayout 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
    >

        <TextView 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:gravity="center"
            android:text="TEST"
            android:textColor="#0099cc"
        />


    </LinearLayout>    


</LinearLayout>

I suppose with this layout, my text “TEST” should be located in the middle of the screen. But the text “TEST” is located on the top of the screen. Why?

I used layout_gravity and gravity with value center, why my “TEST” text located on the top?

Answer 1

use android:gravity="center" in your main layout
