加速度传感器说明:
加速度传感器又叫G-sensor，返回x、y、z三轴的加速度数值。
该数值包含地心引力的影响，单位是m/s^2。
将手机平放在桌面上，x轴默认为0，y轴默认0，z轴默认9.81。
将手机朝下放在桌面上，z轴为-9.81。
将手机向左倾斜，x轴为正值。
将手机向右倾斜，x轴为负值。
将手机向上倾斜，y轴为负值。
将手机向下倾斜，y轴为正值。
加速度传感器可能是最为成熟的一种mems产品，市场上的加速度传感器种类很多。
手机中常用的加速度传感器有BOSCH（博世）的BMA系列，AMK的897X系列，ST的LIS3X系列等。
这些传感器一般提供±2G至±16G的加速度测量范围，采用I2C或SPI接口和MCU相连，数据精度小于16bit。

SweetAlertDialog
非常好用效果很漂亮 的dialog
new SweetAlertDialog(getActivity(), SweetAlertDialog.WARNING_TYPE)

.setContentText("打赏100元人民币")
.setConfirmText("Yes,do it!")
.setConfirmClickListener(new SweetAlertDialog.OnSweetClickListener() {
