Evenly spaced button in Layout

Try something like this:

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical"    >    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="0dp"        android:orientation="vertical"        android:layout_weight="1"        android:gravity="center"        >        <Button            android:id="@+id/btn_f"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="btn_f"            />    </LinearLayout>    <!-- etc --></LinearLayout>

The changes from your original layout are that each inner LinearLayout has a height of zero and a gravity (not layout_gravity) of center. This should cause all the inner linear layouts to have the same height, evenly splitting the parent height, without stretching the buttons themselves.

Try this:

 <LinearLayout           android:layout_width="wrap_content"           android:layout_height="0dp"           android:orientation="horizontal"           android:weightSum="1"           android:gravity="center">     <Button                     android:id="@+id/btn_f"            android:layout_width="0dp"         android:layout_weight="0.5"         android:layout_height="wrap_content"              android:text="btn_f" />      </LinearLayout> 

This will set the button to occupy only half of the screens length.

You seem to be wrapping all buttons in another LinearLayout instead of just keeping them in the parent LinearLayout.

Remove all those immediate LinearLayout so that android:layout_weight takes effect.

To achieve stretching and spacing

• use android:layout_width="fill_parent" in the buttons themselves
• specify margin for spacing
