Center text items in ListView

Question

How can I horizontally center-align text items of the ListView in my Layout?
Honestly, I googled for at least an hour before asking such a basic question.

Thanks.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <EditText
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:hint="Remind..." />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:baselineAligned="false"
        android:orientation="horizontal" >

        <ListView
            android:id="@+id/listviewTimeInterval"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:scrollbars="none" />

         <-- . . . --/>
         <-- more lists of the same kind--/>
         <-- . . .--/>

    </LinearLayout>

</LinearLayout>

Answer 1

I found it impossible to center the items in a ListView if the LisView itself is defined with android:layout_width="wrap_content" This does not make sence, because this parameter should only affect the position of the ListView and not its elements.

Anyway, changing the width of the list to match_parent allows to center the items with their (layout_)gravity attributes.

Answer 2

In the layout of the TextView for your customized ListView xml file use android:gravity="center" . That'll do it.

Answer 3

You need to create your own layout for your listview item, something like this

Example:

textcenter.xml:

<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" >
    <TextView
        android:id="@id/textItem"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

Then, in your code, your have to do this

ArrayAdapter<String> ad = new ArrayAdapter<String>(this, R.layout.textcenter, R.id.textItem, functions);
listView.setAdapter(ad);
