有问题吗？

Answer 1

做以下

步骤1：

在您的build.gradle(模块：应用程序(中更换

编译'info.hoang8f：fbutton：1.0.5' with

编译'com.github.jd-alexander：android-flat-button：v1.1'

或更好的

实现'com.github.jd-alexander：android-flat-button：v1.1'

避免构建警告。

有关图书馆的详细信息可以在此处添加

步骤2：

在您的build.gradle(project(文件

添加

maven {url" https://jitpack.io"}

在您的存储库中

您的存储库结构应该看起来像

allprojects {
repositories {
    google()
    jcenter()
    maven { url "https://jitpack.io" }
}

}

在您的活动中。xml文件

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

总而言之，您的 buid.gradle(模块(应该看起来像这样

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应该看起来像

            fbutton:cornerRadius="4dp"
            />
    </LinearLayout>
</RelativeLayout>

Answer 2

该错误告诉您，由于FBUTTON实现存在错误，因此布局不会被夸大：

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，但是在读取您添加到布局中的属性时，这似乎是一个问题。其中之一：

        app:buttonColor="@color/btnSignUp"
        app:shadowColor="@android:color/black"
        app:shadowEnabled="true"
        app:shadowHeight="5dp"
        app:cornerRadius="4dp"

我会说问题是您在" btsignup"字段中投入的价值，该字段无法转换为颜色(另一种颜色来自Android，因此肯定可以(。�您是否使用颜色格式" #xxxxxx"？在适当的标签上？不要忘记＃。这样的东西(colors.xml(：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="btnSignUp">#3F51B5</color>
</resources>

问候。
