I am developing an app where in one of the activities I have a listview. It is a dynamic listview that is completed with an own arrayadapter, so its extension is unknown. I would like it when it exceeds the size of the screen it reaches down and with scroll down.

To get this, I have to give a fixed size to the list, specifically 471, so that it occupies a large part of the screen and can go up and down. If I give it the match_parent property, it stays in a single row, and only one element remains up, I can scroll but all the elements are left there, up and small.

Is there a way to set the list for all the screens and that it is complete on the screen?

I leave the layout:

<?xml version="1.0" encoding="utf-8"?>
<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:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.oftecnica2.agendajose.MainActivity"
    android:orientation="vertical"
    android:gravity="center"
    >

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/scrollView"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true">


        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <ListView
                android:layout_width="match_parent"
                android:id="@+id/lista"
                android:divider="@drawable/separador"
                android:layout_height="475dp" />
        </LinearLayout>
    </ScrollView>

</LinearLayout>

Here is the own layout that I use to fill the listview

You can do this ..

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

So you do not get complicated ... in this simple way you would have your screen just to show the ListView, well if the request asks for it.

You tried to remove the Action Bar

<style name="NoActionBar" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

First in your main container LinearLayout , You have defined:

  android:layout_width="match_parent"
  android:layout_height="match_parent"

Which is correct, but you have defined a padding which will generate space:

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

Eliminate padding.

Another important point is that you do not need a Scrollview to contain the ListView since it has its own Scroll, it eliminates the ScrollView and its LinearLayout .

This is an example:

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

         <ListView
              android:id="@+id/list"
              android:layout_height="wrap_content"
              android:layout_width="match_parent">
         </ListView>

</LinearLayout>

The first thing is that having a listview within a scrollview is a very bad idea, if you need to have a listview with superior or inferior views you must add the views above or below with the addHeaderView() and% methods addFooterView() .

What is surely happening to you is that the scrollView is taking the size of the listview so that the scrollview has the size of the whole screen add it:

android:fillViewport="true"
