我正在尝试编写＆＃34; deskclock＆＃34;来自Android的应用程序，源代码在此处找到：https://android.googlesource.com/platform/packages/apps/DeskClock/
我在Android SDK中创建了一个新项目，添加了文件，并更新了引用以匹配新的包名称。应用程序将编译并安装在模拟器上，但在启动时它几乎立即崩溃，并出现以下错误：
05-16 20:53:37.927 2628-2628/com.mycompanyname.builtinclock E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.mycompanyname.builtinclock, PID: 2628
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mycompanyname.builtinclock/com.mycompanyname.builtinclock.deskclock.DeskClock}: android.view.InflateException: Binary XML file line #50: Binary XML file line #50: Error inflating class com.android.deskclock.widget.RtlViewPager
我似乎无法找到导致这种情况发生的原因。我已清理并重建项目无效。
我对上述源代码所做的唯一重大更改是更改公司名称以匹配新的软件包名称，并更新每个引用位置的文件中的名称，以消除它之前提供的所有错误会编译。
另一个重大变化是build.gradle文件，我删除了datetimepicker条目（无法弄清楚如何编译），我在依赖项屏幕上重新添加了appcompat依赖项。
如果有人可以帮助我，或者通过指出代码的错误，或者向我展示编译该软件包的更好方法，我将非常感激！如果这是一个愚蠢的问题，我很抱歉。
请参阅下面的两个已更改的文件。
这是gradle文件：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.mycompanyname.builtinclock"
minSdkVersion 23
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:gridlayout-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:support-v13:23.4.0'
}
这是AndroidManifest.xml：

答案 0 :(得分：1)
在布局xml文件中，您仍在使用 com.android.deskclock.widget.RtlViewPager 类。当您更改包名称时，您还需要在xml文件中更改相同的内容
