我有在应用程序，我想有一个Evernote的风格主屏幕布局。到目前为止，我的code是这样的：

I have a layout for the main screen in an app, which I would like to have an evernote style. So far, my code is this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:gravity="center_vertical|center_horizontal"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|left"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/btn1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/button" />

        <ImageButton
            android:id="@+id/btn2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/button" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center"
        android:orientation="horizontal" >

        <ImageButton
            android:id="@+id/btn3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/button" />

        <ImageButton
            android:id="@+id/btn4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/button" />
    </LinearLayout>

</LinearLayout>

这是它的样子：

这是我怎么想它看起来像：

And this is how I'd like it to look like:

我怎么能做到这一点？分组按钮也是这样吗？

How could I achieve this? Grouping the buttons like this?

非常感谢事先！
