吾生也有涯,而知也无涯。这篇文章主要讲述如何摆脱问题' 二进制XML文件第8行：二进制XML文件第8行：使用XYPlot时会膨胀类com.androidplot.xy.XYPlot类]相关的知识，希望能为你提供帮助。
[我正在尝试使用android studio 3.5熟悉android XYplot。我首先测试了几个示例，但最终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" /> < /LinearLayout>

gradle：

apply plugin: 'com.android.application'android { compileSdkVersion 29 buildToolsVersion "29.0.2" defaultConfig { applicationId "com.example.plot_testmy2" minSdkVersion 22 targetSdkVersion 29 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } }dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'androidx.appcompat:appcompat:1.1.0' implementation 'androidx.constraintlayout:constraintlayout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'androidx.test.ext:junit:1.1.1' androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' implementation "com.androidplot:androidplot-core:1.5.7" }

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.**{*; }

答案原因：java.lang.RuntimeException：com.halfhp.fig.FigException：解析键时出错：ticksPerDomainLabel值：2【如何摆脱问题' 二进制XML文件第8行（二进制XML文件第8行：使用XYPlot时会膨胀类com.androidplot.xy.XYPlot类]）】 < com.androidplot.xy.XYPlot android:id="@+id/mySimpleXYPlot" androidplot.gridPadding="4dp|4dp|4dp|4dp" androidplot.ticksPerDomainLabel="2" < --- this line is causing the problem 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" /> 删除这些：

androidplot.gridPadding="4dp|4dp|4dp|4dp" androidplot.ticksPerDomainLabel="2" < --- this line is causing the problem androidplot.ticksPerRangeLabel="4" andsroidplot.title="A Simple XYPlot Example"

它应该起作用。

我从未见过XML属性上的点线属性，它应该是下划线（_）或什么都没有]]这些是此视图接受的所有可能的Attributes。
上面列出的任何一个都没有写在那里，只是不存在。

另一答案None
