Question

这是它看起来像在模拟器：

这是它应该的样子：

我的代码：

<android.support.design.widget.CoordinatorLayout

    android:onClick="ClientHomeSearch" 
    app:rippleColor="@color/primary"/> 

</android.support.design.widget.CoordinatorLayout> 

它看起来像颜色不会出现，浮动操作栏也不会显示我想要的图像。有人能告诉我哪里出了问题？

这是我的build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "b07.cs.plantravel" 
     minSdkVersion 23 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.1.1'
