Put buttons at bottom of screen with LinearLayout?

You need to ensure four things:

• Your outside LinearLayout has layout_height="match_parent"
• Your inside LinearLayout has layout_weight="1" and layout_height="0dp"
• Your TextView has layout_weight="0"
• You've set the gravity properly on your inner LinearLayout: android:gravity="center|bottom"

Notice that fill_parent does not mean "take up all available space". However, if you use layout_height="0dp" with layout_weight="1", then a view will take up all available space (Can't get proper layout with "fill_parent").

Here is some code I quickly wrote up that uses two LinearLayouts in a similar fashion to your code.

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/db1_root"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <TextView        android:id="@+id/textView1"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="@string/cow"        android:layout_weight="0"        android:textAppearance="?android:attr/textAppearanceLarge" />    <LinearLayout        android:layout_width="match_parent"        android:layout_height="0dip"        android:layout_weight="1"        android:gravity="center|bottom"        android:orientation="vertical" >        <Button            android:id="@+id/button1"            style="?android:attr/buttonStyleSmall"            android:layout_width="145dp"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal|center"            android:text="1" />        <Button            android:id="@+id/button2"            style="?android:attr/buttonStyleSmall"            android:layout_width="145dp"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal|center"            android:text="2" />        <Button            android:id="@+id/button3"            style="?android:attr/buttonStyleSmall"            android:layout_width="145dp"            android:layout_height="wrap_content"            android:layout_gravity="center_horizontal|center"            android:text="3" />    </LinearLayout></LinearLayout>

The result looks like similar to this:

You can use a RelativeLayout and align it to the bottom with android:layout_alignParentBottom="true"

Create Relative layout and inside that layout create your button with this line

android:layout_alignParentBottom="true"
