一般振动时间的配置在如下文件：
frameworks/base/core/res/res/values/config.xml
<!-- 长按振动 -->
<!-- Vibrator pattern for feedback about a long screen/key press -->
<integer-array name="config_longPressVibePattern">
<item>0</item>
<item>1</item>
<item>20</item>
<item>21</item>
</integer-array>
<!-- 虚拟按键振动 -->
<!-- Vibrator pattern for feedback about touching a virtual key -->
<integer-array name="config_virtualKeyVibePattern">
<item>0</item>
<item>10</item>
<item>20</item>
<item>30</item>
</integer-array>
<!-- 软键盘按键振动 -->
<!-- Vibrator pattern for a very short but reliable vibration for soft keyboard tap -->
<integer-array name="config_keyboardTapVibePattern">
<item>40</item>
</integer-array>
<!-- 非安全模式启动振动 -->
<!-- Vibrator pattern for feedback about booting with safe mode disabled -->
<integer-array name="config_safeModeDisabledVibePattern">
<item>0</item>
<item>1</item>
<item>20</item>
<item>21</item>
</integer-array>
<!-- 安全模式启动振动 -->
<!-- Vibrator pattern for feedback about booting with safe mode disabled -->
<integer-array name="config_safeModeEnabledVibePattern">
<item>0</item>
<item>1</item>
<item>20</item>
<item>21</item>
<item>500</item>
<item>600</item>
</integer-array>
上面以数组形式的表示的，奇数位置表示暂停时间，偶数位置表示振动时间，单位为 ms
