Answer 1

• 在您的应用程序库文件夹中包含 android-support-design.jar 和 android-support-v4.jar。
• 将设计库导入 Eclipse，位于 \extras\android\support\design。
• 打开项目的属性 -> android -> (Library) Add... -> 选择 design。
• 你应该改变

public class YourActivity extends Activity {
}

到

public class YourActivity extends AppCompatActivity {    
}

• AndroidManifest.xml 并将应用程序的主题更改为

@style/Theme.AppCompat

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat">
