Question

由于一些莫名其妙的原因，我的应用程序崩溃了HTC Desire HD。它在其他手机以及模拟器中都能正常工作。这是崩溃报告：

在为EditText设置值时似乎发生了崩溃。这是XML中的EditText字段：

<EditText style="@style/HomeInput" android:id="@+id/signin_username"
                    android:capitalize="none"
                    android:imeOptions="actionDone"
                    android:inputType="text"
                    android:text=""
                    android:maxLines="1"/>

XML有什么问题吗？如果是，为什么它在模拟器或其他手机中工作？

修改1

这是样式XML

  <style name="HomeInput">
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">wrap_content</item>      
    <item name="android:textSize">@dimen/text_size_small</item>
    <item name="android:textColor">@color/signin_input</item>
    <item name="android:layout_marginTop">10dip</item>
    <item name="android:layout_marginBottom">5dip</item>
    <item name="android:layout_marginLeft">10dip</item>
    <item name="android:layout_marginRight">10dip</item>
</style>

向Google提交错误报告：http://code.google.com/p/android/issues/detail?id=16640&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

应用程序因从xml / preferences.xml中膨胀的EditTextPreference而崩溃。这是崩溃报告：

Answer 1

我终于整理了它！首先，这是我的设置：

UI thread -> AsyncTask.doInBackground -> inflate

这在1.6到2.3以及其他手机（LG和摩托罗拉）的模拟器上运行得非常好，但它会在HTC（Desire和Wildfire）上爆炸。实际错误是由InvocationTargetException引起的InflateException“Error inflating class”，由RuntimeException导致“无法在未调用Looper.prepare（）的线程内创建处理程序”。

我将此设置更改为

UI thread -> create Handler
UI thread -> AsyncTask.doInBackground -> Handler.sendMessage
Handler.handleMessage() -> inflate

这导致完全相同的错误。这很奇怪，因为代码是在UI线程上创建的处理程序内执行的（参见围绕它的**行）。

android.view.InflateException: Binary XML file line #32: Error inflating class <unknown>
    at android.view.LayoutInflater.createView(LayoutInflater.java:513)

...

最后，诀窍是什么：

UI thread -> create Runnable
UI thread -> create Handle
UI thread -> AsyncTask.doInBackground -> Handler.post(Runnable)
Runnable.run -> inflate

就是这样 - 它现在适用于Desire和Wildfire。

不确定您是否遇到同样的问题，但希望这会对您有所帮助。

Answer 2

除非您的手机完全损坏，否则其他应用程序可以显示EditText小部件。因此，HTC固件中的问题是由EditText小部件的定义触发的。从窗口小部件或样式中一次删除一个属性，直到它起作用 - 删除的最后一个属性是你的问题。

我会从android:text=""开始，因为它充其量是多余的，可能是你问题的根源。这些似乎也很可能是候选人：

android:maxLines="1"
android:capitalize="none"
android:inputType="text"

最后，这是HTC固件中的一个错误 - 这只是试图解决任何错误的问题。

Answer 3

这可能包含在您未显示的样式中，但大部分时间需要指定：

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

应用程序在Desire HD中崩溃
