升級的Android工作室2.2.3 問題後android.support.design.widget.CoordinatorLayout

Question

我現在面臨的問題呈現問題是使用android.support.design.widget.CoordinatorLayout 它表明這個錯誤

The following classes could not be found: - android.support.design.widget.CoordinatorLayout (Fix Build Path, Edit XML, Create Class) - android.support.design.widget.TextInputLayout (Fix Build Path, Edit XML, Create Class) Tip: Try to build the project. Tip: Try to refresh the layout. \app\src\main\res\layout\activity_main.xml" in attribute "imeActionId" is not a valid integer

我試圖修復構建路徑，但沒有爲我工作。 當我建立並運行它顯示

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.design.widget.CoordinatorLayout" on path: DexPathList[[zip file "/data/app/fitness.aclass.fitness-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:511) at java.lang.ClassLoader.loadClass(ClassLoader.java:469) at android.view.LayoutInflater.createView(LayoutInflater.java:571) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:743) at android.view.LayoutInflater.inflate(LayoutInflater.java:482)  at android.view.LayoutInflater.inflate(LayoutInflater.java:414)  at android.view.LayoutInflater.inflate(LayoutInflater.java:365)  at android.support.v7.app.AppCompatDelegateImplV9.setContentView(AppCompatDelegateImplV9.java:284)  at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:140)  at fitness.aclass.fitness.MainActivity.onCreate(MainActivity.java:11)  at android.app.Activity.performCreate(Activity.java:6092)  at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1112)  at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2468)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2595)  at android.app.ActivityThread.access$800(ActivityThread.java:178)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1470)  at android.os.Handler.dispatchMessage(Handler.java:111)  at android.os.Looper.loop(Looper.java:194)  at android.app.ActivityThread.main(ActivityThread.java:5624)  at java.lang.reflect.Method.invoke(Native Method)  at java.lang.reflect.Method.invoke(Method.java:372)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:959)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:754)  Suppressed: java.lang.ClassNotFoundException: android.support.design.widget.CoordinatorLayout at java.lang.Class.classForName(Native Method) at java.lang.BootClassLoader.findClass(ClassLoader.java:781) at java.lang.BootClassLoader.loadClass(ClassLoader.java:841) at java.lang.ClassLoader.loadClass(ClassLoader.java:504) ... 22 more Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available

這是我的build.gradle（應用模塊）

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 24 
    buildToolsVersion "24.0.2" 
    defaultConfig { 
     applicationId "fitness.aclass.fitness" 
     minSdkVersion 16 
     targetSdkVersion 24 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    compile 'com.android.support:appcompat-v7:24.2.0' 

    testCompile 'junit:junit:4.12' 
} 

這個任何解決方案！

Answer 1

CoordinatorLayout是設計庫的一部分。所以，如果你需要使用過時的版本，由於某種原因，你應該添加

compile 'com.android.support:design:25.2.0'

或24.2.0版本。

Answer 2

嘗試從Build菜單中清理項目，因爲發生了Gradle構建緩存。 還有一件事情是嘗試使用最新的，因爲它們解決了很多問題。
