Android Studio - 手機震動類（Vibrator Class）（八十一）

Android Studio - 手機震動類（Vibrator Class）（八十一）：

當處於一個寧靜的環境，例如在劇院、圖書館、會議、教堂或嘈吵環境，手機便利用機內的震動功能作為提示，通知用戶，便可以避免錯過重要時刻。Android Studio 提共了手機震動類（Vibrator Class），可以程式震動功能，方便編程。

手機調成靜音模式標示
Summary：

Constants

Description

int

VIBRATION_EFFECT_SUPPORT_NO

Vibration effect support: unsupported - This effect is not natively supported by the underlying hardware, although the system may still play a fallback vibration. Constant Value: 2 (0x00000002)

int

VIBRATION_EFFECT_SUPPORT_UNKNOWN

Vibration effect support: unknown - The hardware doesn't report its supported effects, so we can't determine whether the effect is supported or not. Constant Value: 0 (0x00000000)

int

VIBRATION_EFFECT_SUPPORT_YES

Vibration effect support: supported - This effect is supported by the underlying hardware. Constant Value: 1 (0x00000001)

Android Studio - 手機震動程式（Vibrator Program）（八十）

Android Studio - 手機震動程式（Vibrator Program）（八十）：

手機震動程式（Vibrator Program）主要是打開震動器（Vibrator），然後傳遞一個 int 數值或陣列，它們是以毫秒（ms）為單位，代表打開或關閉振動器的持續時間，如 1000 是代表 1000ms 等於 1s （vibrator.vibrate(1000) ）。需要重複使用，可以在第二值加入 0 （vibrator.vibrate(mVibratePattern, 0) ），禁用重複可以在第二值加入 -1 （vibrator.vibrate(mVibratePattern, -1)）。

Android 手機震動程式（Vibrator Program）
  • 操作系統：Windows 7 64-bit 版本
  • 開發環境：Android Studio 4.0.1 版本
  • 原程式：C:\Development\Development_Android\Android_Project\DIY-Android-152-02 Vibration Bugworkshop
  • 程式：C:\Development\Development_Android\Android_Project\DIY-Android-152-02 Vibration Bugworkshop
  • 測試環境：Vivo（維沃）X5Max Android 4.4.4（KitKat）版本

Android 手機震動程式（Vibrator Program）編程步驟：
  • 設定 Vibrator 許可權限後 - AndroidManifest.xml
  • 設定 Vibrator Data 參數
  • 設定 Button

AndroidManifest.xml 獲取 Vibrator 許可權：

<uses-permission android:name="android.permission.VIBRATE" />
