java – 渲染android.support.design.widget.CoordinatorLayout

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.
appsrcmainreslayoutactivity_main.xml” in attribute “imeActionId” is not a valid integer

我试图修复构建路径,但不适合我.
当我构建并运行它显示

这是我的build.gradle(App Module)

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'
}

任何解决方案.！
