android.view.InflateException: Binary XML file line #21: Error inflating class android.support.design.widget.FloatingActionButton
                                                                            at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2693)

我的 xml 代码:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white">

    <ListView
        android:id="@+id/listview_diary"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipToPadding="false"
        android:divider="@null"
        android:dividerHeight="16dp"
        android:fadingEdge="none"
        android:fitsSystemWindows="true"
        android:padding="12dp"
        android:scrollbars="none"
        android:background="@android:color/white"/>

    <android.support.design.widget.FloatingActionButton
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/fab_add_diary"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_margin="16dp"
        android:clickable="true"
        android:padding="8dp"
        android:src="@mipmap/ic_add"
        app:backgroundTint="@color/colorPrimary"
        app:borderWidth="0dp"/>

</RelativeLayout>

我的类扩展了一个 AppCompatActivity 类。

我的风格:

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

我的 Gradle :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "25.0.0"

    defaultConfig {
        applicationId "***.***.***"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        jackOptions {
            enabled true
        }
        // Enabling multidex support.
        multiDexEnabled true
    }
    buildTypes {
        release {
            debuggable false
            minifyEnabled false
            shrinkResources false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    dexOptions {
        javaMaxHeapSize "2g"
        incremental true
        preDexLibraries = false
    }
}
repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    maven { url 'https://raw.github.com/felipecsl/m2repository/master' }
    //  maven { url "https://jitpack.io" }
    mavenCentral()

}
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile('com.github.florent37:materialviewpager:1.2.0@aar') {
        transitive = true
    }
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:recyclerview-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.android.support:cardview-v7:24.0.0'
    compile 'com.android.support:support-v4:24.0.0'
    ...

Answer 1

试试这个
1.使用安装最新版本的 sdk 管理器更新设计支持库和 appCompat 库。
2.使用Appcompat主题。
3. 从 AppCompatActivity 而不是 Activity 扩展您的 Activity。
4.尽量保持两个库的版本一致

compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'

5.在所有这些清理你的项目并运行之后。
