Question

我的应用程序有大约10个按钮的菜单。在我的测试手机（HTC ONE X）上，所有按钮都正确显示。在我的另一部测试手机（HTC Desire C）屏幕上有几个按钮。缺少底部的2个按钮和textview。

如何使整个布局适合各种屏幕尺寸？我是否必须在运行时获取屏幕大小，例如使用getDisplayMetrics等？

先谢谢，马特。

Answer 1

您需要针对您将使用的最小屏幕尺寸进行开发，或者您需要单独的布局，其中较小的布局较少放在一行并且包含在ScrollView中。

Answer 2

为什么不将父布局放在ScrollView中，这样当屏幕太小时，用户就可以向下滚动以查看隐藏的项目。您的布局应如下所示：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" 
xmlns:android="http://schemas.android.com/apk/res/android">

<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/carefreebgscaledlighting"

<TextView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    android:textColor="#003F87" />

<TextView
    android:id="@+id/spacerasnexttextviewclasheswithbg"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:textAppearance="?android:attr/textAppearanceLarge"
     />

<TextView
