All Buttons Same Size, Center Text(Android)

I have 6 buttons. The XML is as follows for each one. How to go about changing them so that the button开发者_如何学JAVA text is centered and the they are all the same size?

I assumed that setting the size would do the trick?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>


<Button 
android:id="@+id/Button1" 
android.layout_height="100px"
android.layout_width="60px"
android:layout_height="wrap_content" 
android:layout_width="wrap_content" 
android:text="BUTTON1"/>

Use fill_parent for all child height and layout_weight="1", hope it will work

You should use

android:layout_width="fill_parent"

instead of

android:layout_width="wrap_content" 

in button attributes. Button width can be changed by android:padding attribute in LinearLayout Example:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:paddingLeft="10px"
 android:paddingRight="10px"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 >


 <Button 
 android:id="@+id/Button1" 
 android:layout_height="wrap_content" 
 android:layout_width="fill_parent" 
 android:text="BUTTON1"/>

If you want to set the text center of the button use the: android:gravity="center_vertical|center_horizontal" attribute.

For the size use the android:layout_height="100px" and android:layout_width="60px" attributes.

This is the full xml layout of the button:

     <Button 
 android:id="@+id/button" 
 android:layout_height="100px" 
 android:layout_width="60px"
 android:gravity="center_vertical|center_horizontal" 
 android:text="Your text!"/>
