使用XYPlot时如何摆脱问题“二进制XML文件第8行:二进制XML文件第8行:膨胀类com.androidplot.xy.XYPlot的错误”

2020年7月28日 14点热度 0条评论

我正在尝试使用android studio 3.5使自己熟悉android XYplot。
我首先测试了几个示例,但最后都出现了相同的错误-
Caused by: android.view.InflateException: Binary XML file line #8: Binary XML file line #8: Error inflating class com.androidplot.xy.XYPlot Caused by: android.view.InflateException: Binary XML file line #8: Error inflating class com.androidplot.xy.XYPlot
然后应用崩溃。

我真的很感谢任何建议摆脱这个问题。谢谢!

我做了什么:
下面显示了我尝试过的示例之一(this)的logcat输出。我用XYPlot库更新了Gradle,而且正如我在搜索时注意到的那样,我也想更新ProGuard。最后还提到了更新的ProGuard。

main_activity.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

    <com.androidplot.xy.XYPlot
        android:id="@+id/mySimpleXYPlot"
        androidplot.gridPadding="4dp|4dp|4dp|4dp"
        androidplot.ticksPerDomainLabel="2"
        androidplot.ticksPerRangeLabel="4"
        andsroidplot.title="A Simple XYPlot Example"
        android:layout_width="fill_parent"
        android:layout_height="527dp"
        android:layout_marginLeft="10px"
        android:layout_marginTop="10px"
        android:layout_marginRight="10px" />

ProGuard:

# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile
-keep class com.androidplot.**{*;}

解决方案如下:

删除这些:

    androidplot.ticksPerDomainLabel="2" <--- this line is causing the problem
    androidplot.ticksPerRangeLabel="4"

它应该工作。

我从未见过XML属性上的点线属性,它应该是下划线(_)或一无所有

这些是该视图接受的所有可能的

上面没有列出任何代码,只是不存在。
