如何在Android中以编程方式振动设备？

当涉及到用户体验时，也会考虑肝反馈。因此，在此讨论中，已经讨论了各种类型的触觉或设备的振动类型。例如，单击触觉或长按按钮触觉。在触觉反馈中讨论了五种不同类型的振动模式：

1. 设备的默认振动
2. 点击效果振动
3. 双击效果振动
4. 重击声振动
5. 滴答声振动

注意，我们将使用Java语言实现该项目。

在Android中实现触觉反馈的步骤

第1步：创建一个空的活动Android Studio项目

• 创建一个空的活动android studio项目。
• 参考Android |如何在Android Studio中创建/启动新项目?
• 请注意，选择Java作为编程语言。

步骤2：使用activity_main.xml

• 在此讨论中，讨论了四种不同类型的触觉。
• 因此，要生成该触觉，布局中包含四个不同的按钮。在activity_main.xml文件中调用以下代码。
• 确保为所有按钮提供适当的ID，以便在MainActivity中处理它们。 Java文件。

步骤3：在AndroidManifest文件中调用“振动”权限

设备的振动需要许可。在AndroidManifest文件中调用以下代码。

步骤4：使用MainActivity。 Java文件

• 据说有五种不同的振动。对于这五种振动，每种振动都有一个常数。那些是：

DEFAULT_AMPLITUDE -> for default vibration of the device

EFFECT_CLICK -> for single click haptic

EFFECT_DOUBLE_CLICK -> for double click of the view

EFFECT_HEAVY_CLICK -> for heavy click effect of the view

EFFECT_TICK -> for tick effect vibration

• 在MainActivity中调用以下代码。 Java文件。在代码内部添加了注释，以更详细地了解代码。
