Android: How can you align a button at the bottom and listview above?
A FrameLayout
s purpose is to overlay things on top of each other. This is not what you want.
In your RelativeLayout
example you set the ListView
s height and width to MATCH_PARENT
this is going to make it take up the same amount of space as its parent, and thus take up all of the space on the page (and covers the button).
Try something like:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
The layout_weight
dictates how the extra space is to be used. The Button
does not want to stretch beyond the space it requires, so it has a weight of 0. The ListView
wants to take up all of the extra space, so it has a weight of 1.
You could accomplish something similar using a RelativeLayout
, but if it is just these two items then I think a LinearLayout
is simpler.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
>
<ListView android:id="@+id/ListView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
</ListView>
<FrameLayout android:id="@+id/FrameLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
android:layout_gravity="center_horizontal">
</Button>
</FrameLayout>
</LinearLayout>
