プロジェクトにGoogleデザインサポートライブラリが含まれているかどうかを確認します。このようにアプリレベルのGradleファイルに含めることができます-

compile 'com.Android.support:design:23.3.0'
21
jaibatrik

また、gradelにサポートライブラリを追加する前に、ターゲットのSDKバージョンを確認してください

例えば：

ターゲットSDK = 25の場合

その場合、サポートライブラリはcom.Android.support:design:25.4.0になります。または、minSdkVersionとtargetSdkVersionの間にある場合もあります。
