不使用FAB，没有这样的错误

Answer 1

尝试使用compile 'com.android.support:design:26.+'浮动按钮，如下面的代码

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-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:cardview-v7:26.+'
    compile 'com.android.support:design:26.+'


}
