为什么我的布局不扩展以适应其他屏幕？我正在开发nexus 7，布局应该修复以适应整个页面，但它没有。这是我的布局代码：

<?xml version="1.0" encoding="utf-8"?>
<!--

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"

    >
    <LinearLayout style="@style/TitleBar">
        <ImageButton style="@style/TitleBarAction"
            android:contentDescription="@string/description_home"
            android:src="@drawable/title_home"
            android:onClick="onClickHome" />

        <ImageView style="@style/TitleBarSeparator"

你只是没有足够的内容来适应屏幕。您可以将布局重力设置为中心以使所有内容居中。

您可以为手机和平板电脑 (7" + 10") 制作自定义布局，并尝试重新排序元素以更好地使用房地产

顺便说一句：SDK 预览设置为 Nexus One，它的屏幕尺寸要小得多。这就是为什么它在 sdk 中看起来如此不同的原因。
