//单击按钮时，我通过使用位置侦听器获取纬度和经度。有时它会调用位置侦听器，有时不会。我必须重新启动电话才能正常工作。请提供最佳解决方案。

mLocationManager.removeUpdates(mLocationListener);从这部分代码中 删除：

mLocationManager.removeUpdates(mLocationListener); //REMOVE THIS LINE
if (!mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
    mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 2000, 10, mLocationListener);
} else {
    mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, mLocationListener);
}

您应该做的另一件事是在单击按钮mbtnCheckin后禁用按钮并等待获取位置以再次启用它。这可以防止在处理最后一个位置之前再次单击按钮
