嘿，我刚刚开始学习android studio。然后我通过在youtube上观看一些教程并学习它来学习。但是当我想测试或启动项目时，我得到了一些错误消息二进制XML文件行＃38：错误导致类info.hoang8f.widget.FButton等。

当我想运行应用程序时。应用程序突然关闭，没有任何警告。 （我直接通过Android智能手机运行它）。 这是main和app的代码
这是我使用的颜色格式

<color name="colorPrimary">#004d40</color>
<color name="colorPrimaryDark">#00251a</color>
<color name="colorAccent">#39796b</color>
<color name="btnSignUp">#39796b</color>
<color name="btnSignActive">#A9d440</color>
</resources>
有什么问题？
答案 0 :(得分：1)
执行以下操作
第1步：
在上面的build.gradle（Module：app）中 取代
编译'info.hoang8f：fbutton：1.0.5'与
编译'com.github.jd-alexander：android-flat-button：v1.1'
或更好
实施'com.github.jd-alexander：android-flat-button：v1.1'
避免构建警告。
关于libray的详细信息可以是foud here
第2步：
在Build.gradle（项目）文件中
添加
maven {url“https://jitpack.io”}
在您的存储库中
您的存储库结构应该如下所示
allprojects {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }
}
}
在您的activity.xml文件中
添加
xmlns:fbutton="http://schemas.android.com/apk/res-auto"
在相对布局声明之后，然后使用 fbutton 属性而不是 app
总之，您的 buid.gradle（模块）应如下所示
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.example.exochese.project1"
minSdkVersion 21
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
//add library
compile 'com.google.firebase:firebase-core:12.0.0'
compile 'com.google.firebase:firebase-database:12.0.0'
compile 'com.github.jd-alexander:android-flat-button:v1.1'
compile 'com.rengwuxian.materialedittext:library:2.1.4'
}
apply plugin: 'com.google.gms.google-services'
您的activity_main.xml应如下所示
<?xml version="1.0" encoding="utf-8"?>

答案 1 :(得分：0)
该错误告诉您布局无法膨胀，因为您的FButton实现存在错误：
Caused by: java.lang.UnsupportedOperationException: Can't convert to color: type=0x5
at android.content.res.TypedArray.getColor(TypedArray.java:406)
at info.hoang8f.widget.FButton.parseAttrs(FButton.java:116)
您没有显示FButton类，但在初始化时似乎是一个问题，同时读取您添加到布局中的属性。其中之一：
app:buttonColor="@color/btnSignUp"
app:shadowColor="@android:color/black"
app:shadowEnabled="true"
app:shadowHeight="5dp"
app:cornerRadius="4dp"
我说问题是你在“btSignUp”字段中放置的值，它不能转换为颜色（另一种颜色来自Android，所以它肯定没问题）。 ¿你使用的颜色格式是“#xxxxxx”吗？在适当的标签上？别忘了＃。像这样的东西（colors.xml）：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="btnSignUp">#3F51B5</color>
</resources>
问候。
