我的活動是：

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     findViewById(R.id.fab).setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
       Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG).show(); 
       } 
      }); 

    } 
}

activity_main.xml中：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="end|bottom"/> 

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

styles.xml：

<resources> 
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light"> 

    </style> 

    <style name="AppTheme" parent="AppBaseTheme"> 

    </style> 

</resources>

我發現了一些類似的問題，但沒有解決方案窩爲我而去。任何人都可以幫到我嗎？非常感謝你。

你加上'編譯「com.android.support：設計：23.1.1'' –

@邏輯謝謝你的回答。我很抱歉，但我不知道哪個文件應該包含這一行。你能告訴我一個文件名或者一個路徑嗎？（我使用Eclipese） –

你使用的是android studio嗎？添加它作爲你的gradle中的依賴。 –

更改設計庫從 \sdk\extras\android\support\design to eclipse workspace目標至23
導入支持設計庫。
程序兼容性的開放project.properties和設計庫和目標它23
清潔完整的工作區
運行

希望它可以幫助
