在外部库组件使用情况下，误差夸大类

Question

i创建一个简单的小部件，该小部件使用PIE/DONUT图表（Circle Progress Bar）提供相同的数据。我想使用一些外部组件，所以我选择了：

com.github.lzyzsd.circleprogress.ArcProgress

我将ArcProgress组件放在我的widget.xml上，我可以在预览选项卡中清楚地看到它。没有汇编，构建或任何其他错误。当我运行应用程序并将小部件放在主屏幕上时，我将面临一个例外：

W/AppWidgetHostView: updateAppWidget couldn't find any view, using error view

我认为Gradle有一些问题，因为我的第一次尝试是：

az.plainpie.PieView

结果是相同的（但是classNotfound是" az.plainpie.pieview"）。

我的widget.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:custom="http://schemas.android.com/tools"

              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:padding="@dimen/widget_margin"
              android:background="#AA000000">
              <!--xmlns:plainpie="http://schemas.android.com/apk/res-auto"-->

    <LinearLayout

            plainpie:inner_text_visibility="true"/>  -->
        <com.github.lzyzsd.circleprogress.ArcProgress
            android:id="@+id/arc_progress"
            android:layout_width="100dp"
            android:layout_height="100dp"
            app:arc_bottom_text_size="10sp"
            app:arc_progress="55"
            app:arc_bottom_text="VALUE"/>
        <TextView
            android:id="@+id/countryText"

            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:text="temp"
            android:textSize="@dimen/text_size_big"
            android:textStyle="bold"
            android:textColor="@color/colorWhite"/>
    </LinearLayout>
</LinearLayout>

项目gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

模块gradle：

apply plugin: 'com.android.application'

}

我尝试了干净的项目，卸载应用程序，使用其他手机。我的Android Studio没有选中"离线工作"，并已检查了建议的"默认Gradle包装器"。我搜索了解决方案，但它们都没有解决我的问题。你能看到怎么了吗？

不幸的是，您无法在应用程序窗口小部件中使用这些自定义视图，如文档所述：

如果您熟悉布局，则创建应用程序小部件布局很简单。但是，您必须意识到应用程序小部件布局是基于的在远程视图上，不支持各种布局或查看窗口小部件。

在Android上阅读有关相关问题的阅读：具有自定义视图的AppWidget不起作用
