java - 尝试编译和启动一个开源 android 应用程序，出现以下错误 : Error inflating class com. android.deskclock.widget.RtlViewPager

Question

我正在尝试从 Android 编译“deskclock”应用程序，源代码在这里: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。该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

我似乎找不到导致这种情况发生的原因。我已经清理并重建了该项目，但没有任何效果。

我对上述源代码所做的唯一主要更改是更改公司名称以匹配新的包名称并在每个引用位置的文件中更新它以消除它在编译之前给出的所有错误.

另一个大的变化是 build.gradle 文件，我在其中删除了 datetimepicker 条目(无法弄清楚如何编译它)，然后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，指出代码有什么问题，或者向我展示编译该程序包的更好方法，我将非常感激!如果这是一个愚蠢的问题，我深表歉意。

请参阅下面更改的两个文件。

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:

Answer 1

在您的布局 xml 文件中，您仍在使用类 com.android.deskclock.widget.RtlViewPager。当您更改包名称时，您也需要在 xml 文件中更改相同的名称
