Im sorry for my English, thats why i tried to express it with the pictures. I hope u understood what my problem is.

Thats what the Java Code looks like at the moment, not much, no Listener added yet. Im just trying to find out how to make it look better at the moment:

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    lvItems = (ListView)  findViewById(R.id.listView);
    items = new ArrayList<String>();
    items.add("First Item");
    items.add("Second Item");
    itemsAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,items );
    lvItems.setAdapter(itemsAdapter);

}

and this is the XML Code at the moment:

<RelativeLayout 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"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Add Item"
        android:id="@+id/button"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true" />

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/editText"
        android:layout_alignTop="@+id/button"
        android:layout_alignParentStart="true"
        android:layout_marginLeft="10dip"
        android:layout_toStartOf="@+id/button"
        android:layout_marginTop="10dip"
        android:layout_marginRight="5dip"
        android:text="Enter a new Item" />

    <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/listView"
        android:layout_centerHorizontal="true"
        android:layout_above="@+id/button"
        android:gravity="top"
     />
</RelativeLayout>

Answer 1

You can use Collections.reverse(yourarraylist);

For this approach you can change list order

Answer 2

You can just add

android:layout_alignParentTop="true"

To your listView.
