    <p>I have a LinearLayout with 3 or 4 views (Buttons and ImageButtons) inside, and I want that all of them have the same size to fit entirely the layout, like shown in the picture below <img src="https://i.stack.imgur.com/P1Lx7.png" alt="example"> The same thing must be done either in horizontal and in vertical.</p> <p>the xml of the LinearLayout is this:</p> <pre><code> &lt;LinearLayout android:id="@+id/discover_right_action_bar" android:layout_width="64dp" android:layout_height="match_parent" android:layout_alignParentRight="true" android:layout_below="@id/top_navi_bar" android:background="@color/smart_dark_grey" android:gravity="center" android:orientation="vertical" android:paddingBottom="5dp" android:paddingTop="5dp" &gt; &lt;ImageButton android:id="@+id/home_ib_friend" android:layout_width="60dp" android:layout_height="60dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:saveEnabled="false" android:scaleType="center" android:src="@drawable/ic_action_select_all" /&gt; &lt;ImageButton android:id="@+id/home_ib_camera" android:layout_width="60dp" android:layout_height="60dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:saveEnabled="false" android:scaleType="center" android:src="@drawable/ic_action_camera" /&gt; &lt;ImageButton android:id="@+id/ib_prof_mon_meetings" android:layout_width="60dp" android:layout_height="60dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:saveEnabled="false" android:scaleType="centerInside" android:src="@drawable/clock" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>Now I can only set or the size manually in dp, or set it to wrap_content, but than there would be space at the beginning and at the end of the layout.</p> <p>I've tried something with the layout_weight attribute but I don't know well how to use it.</p> <p>I've tried also with getting the real size of the layout (via ViewTreeObserver) and set the size to the internal children but it doesn't work because I couldn't get the real dimension of the layout.</p>

    1. COHow much views are there in your layout? is it 3 or 4? You can do it simply using weight sum and layout_weight. How you tried it? If not i can give you a example

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
