编辑：添加相对布局，看它是否适合你，让我知道，如果它的工作原理。您将需要调整10px的，以获得所需的距离。我看到，如果有更好的方式来做到这一点，该距离为更具活力。

Added relative layout to see if it works for you, let me know if it works. You will need to adjust the "10px" to get the desired distance. I am seeing if there is a better way to do this, where the distance is more dynamic.

可以使按钮alignParentLeft和alignParentRight让他们对准屏幕的右侧和左侧。但是，我仍然无法得到这两种观点之间的文本。

You can make the buttons "alignParentLeft" and "alignParentRight" to get them to align with the right and left side of the screen. However, i am still having trouble getting the text between the two views.

您可以为布局XML文件做到这一点。使它成为一个horozontal布局，首先添加的第一个按钮，然后在文本视图，然后是第二个按钮。会后不久XML的例子。

You could do this in your xml file for the layout. Make it a horozontal layout and add the first button first, then the text view, then the second button. Will post xml shortly for an example.

    <RelativeLayout 
        android:id="@+id/LinearLayout01"
        android:orientation="horizontal" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:text="button1" 
            android:layout_alignParentLeft="true"
            android:layout_marginRight="10px"
            android:id="@+id/button1button"></Button>
        <EditText 
            android:layout_height="wrap_content" 
            android:id="@+id/firstedittext"
            android:layout_toRightOf="@id/button1button"
            android:layout_marginRight="10px"
            android:layout_width="wrap_content"></EditText>
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@id/firstedittext"
            android:text="button2" 
            android:id="@+id/button2button"></Button>
