Answer 1

它好像是把button放在一个单独的布局中去的，外面有个类似表格的东西限制着

Answer 2

1.采用linearlayout布局：
    <LinearLayout
        android:id="@+id/main"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        >
        <LinearLayout
            android:id="@+id/content"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:orientation="vertical"
            />
            
        <LinearLayout
            android:id="@+id/bottom_panel"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            >
            <Button
                android:id="@+id/done"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:text="done"
                />
            <Button
                android:id="@+id/revert"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:text="revert"
                />
        </LinearLayout>
    </LinearLayout>
2. 采用relativelayout布局：
    <RelativeLayout
        android:id="@+id/main"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        >
        <LinearLayout
            android:id="@+id/content"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical"
            />
            
        <LinearLayout
            android:id="@+id/bottom_panel"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_alignParentBottom="true"
            >
            <Button
                android:id="@+id/done"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:text="done"
                />
            <Button
                android:id="@+id/revert"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_gravity="center_vertical"
                android:text="revert"
                />
        </LinearLayout>
    </RelativeLayout>
