Question

我在模拟器（2.2版）上运行我的Android应用程序，它运行正常。但是，当我在我的Android设备（版本4.1）上尝试应用程序时，它不起作用。我在日志中收到错误如下：

这是我的Manifest.xml：

                  android:screenOrientation="portrait"

    <!--  <uses-sdk android:minSdkVersion="3"></uses-sdk>-->
    <supports-screens

</manifest>

您是否知道如何在我的设备上成功运行该应用程序？

Answer 1

newView(...)中定义的自定义列表项视图缺少android:layout_width属性。需要始终将（以及layout_height属性）设置为fill_parent或wrap_content

查看您在代码中夸大的xml布局文件：example.smartdialup.PhoneSpellDialer$ContactListAdapter.newView(PhoneSpellDialer.java:720)

RelativLayout那里或者一个，如果它可能是子视图。

Answer 2

日志说：

二进制XML文件行＃73：您必须提供layout_width属性。

表示您忘记在“活动视图”的Xml布局中添加android:layout_width="wrap_content"。

Answer 3

很奇怪你在模拟器和真实设备之间得到了“差异”，因为错误也应该发生在模拟器上。这是我在模拟器和真实设备中进行开发的原因之一，两者之间的行为差异超出了您的喜好。

XML文件行＃73：您必须提供layout_width属性。

此错误非常简单，您添加到布局XML的每个元素都应该具有layout_width和layout_height，以便Android知道如何显示它们。

您尚未提供布局XML，因此我无法向您显示更正的布局。我布局的一个例子是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="#FFFFFF">
    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </ListView>
</LinearLayout>

请注意，layout_width和layout_height正在所有“XML标记”中使用，因此Android知道如何定位它们。

match_parent是其中一个值，您可以在Android开发者网站上找到您需要的值： http://developer.android.com/guide/topics/resources/layout-resource.html#layoutvalues

提示：您正在使用Eclipse进行Android开发？输入：android：layout_width =“然后按CTRL +空格键它应该自动完成;）

我的Android应用程序正在使用模拟器，但不在Android设备上
