Non-visible component that can detect shaking and measure acceleration approximately in three dimensions using SI units (m/s²). The components are: <ul><li> <strong>xAccel</strong>: 0 when the phone is at rest on a flat surface, positive when the phone is tilted to the right (i.e., its left side is raised), and negative when the phone is tilted to the left (i.e., its right size is raised).</li> <li> <strong>yAccel</strong>: 0 when the phone is at rest on a flat surface, positive when its bottom is raised, and negative when its top is raised. </li> <li> <strong>zAccel</strong>: Equal to -9.8 (earth''s gravity in meters per second per second when the device is at rest parallel to the ground with the display facing up, 0 when perpendicular to the ground, and +9.8 when facing down. The value can also be affected by accelerating it with or against gravity. </li></ul>

<p>非可视组件，可以用于侦测晃动，并测出加速度三个维度分量的近似值，单位为米/秒²(m/s²)，分别为:</p><ul><li><strong>X分量</strong>: 当手机在平面上静止时，其值为零；当手机向左倾斜时(即，右侧升起)，其值为正；而向右倾斜时(左侧升起)，其值为负。</li><li><strong>Y分量</strong>: 当手机在平面上静止时，其值为零；当手机顶部抬起时，其值为正；而当底部抬起时，其值为负。</li><li><strong>Z分量</strong>: 当设备屏幕朝上地静止在与地面平行的平面上时，其值为9.8(地球的重力加速度)；当垂直于地面时，其值为0；当屏幕朝下时，其值为-9.8。无论是否由于重力的原因，让手机加速运动，就会改变它的加速度分量值。</li></ul>
