Android how to align headings to listview items

Question

I have a Listview in my application, Which I am trying to put a head for each 'Coloumn' however I cant get them to align correctly.

I have made the heading linearlayout items the same layout params as the listView items but they still dont align.

Here is an example app I made to demonstrate the issue.

I have enabled the developer boarder lines so you can easily see how its not aligned.

Here is the list view display item:

<TextView
    android:id="@+id/rhinoZoneDisplayItem_textView_zoneNumber"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:gravity="center"
    android:paddingRight="5dp"
    android:text="1:"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<TextView
    android:id="@+id/rhinoZoneDisplayItem_textView_status"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="2"
    android:clickable="false"
    android:gravity="center"
    android:text="Status"
    android:textAppearance="?android:attr/textAppearanceMedium" />
 </LinearLayout>

and the headings linear layout:

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="5dp"
    android:layout_marginTop="5dp"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_weight="1"
        android:gravity="center_horizontal"
        android:text="Zone"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_weight="2"
        android:gravity="center_horizontal"
        android:text="Status"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>

Answer 1

What your doing is correct when your using Layout-Weights make sure you set the width as "0dp" rather than wrap-content. So as to get all Heading and list view items to align correctly and give equal weights for each column.

Answer 2

Use match_parent for TextView width.

Answer 3

You can put in each item of the list the same value for the field

android:layout_marginLeft="50dp"

this is just an example of the value, in this way all the elements are aligned on left side.
