在实现一个包含EditText、Logo和ButtonBar的登录界面时，遇到在小屏幕设备上显示不全的问题。当屏幕旋转或者尺寸过小时，整个主视图无法完全显示。尝试将内容放入ScrollView中，但导致了两个问题：一是ScrollView在某些情况下不滚动，二是ButtonBar会覆盖键盘，进一步遮挡屏幕。原本将按钮放在ScrollView内可以正常工作，但现在将它们移至ButtonBar后，如何解决这个问题成为一个挑战。

I'm trying to implement a login view where several EditTexts and a logo are displayed on the screen with a ButtonBar at the bottom, something like this:

The problem is that on very small screens, especially when they are rotated sideways, the entire main view doesn't fit onto the screen.

I currently have

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#234C59" >

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:paddingTop="5dip"

android:paddingLeft="15dip"

android:paddingRight="15dip"

android:orientation="vertical" >

android:id="@+id/logo"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:scaleType="fitCenter"

android:layout_centerHorizontal="true"

android:src="@drawable/logo" />

android:id="@+id/input_email"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop="10dip"

android:inputType="textEmailAddress"

android:singleLine="true"

android:hint="Username or email" />

android:id="@+id/input_password"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop=""

android:inputType="textPassword"

android:singleLine="true"

android:hint="Password" />

android:id="@+id/buttonbar_login"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_alignParentBottom="true"

android:orientation="horizontal"

style="@android:style/ButtonBar" >

android:id="@+id/button_signup"

android:layout_width="0dip"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="Sign Up" />

android:id="@+id/button_login"

android:layout_width="0dip"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="Log In" />

I've tried encapsulating the first LinnearLayout in a ScrollView that looks like this:

android:layout_width="fill_parent"

android:layout_height="fill_parent">

But that introduces two problems:

The ScrollView doesn't scroll, even on screens where the data doesn't all fit

The ButtonBar floats on top of the onscreen keyboard, obscuring even more of the screen when the keyboard comes up.

Everything worked great when I had the buttons inside the ScrollView, but now that I have them in the ButtonBar I'm having a lot of trouble figuring this out.
