java - GPS 坐标未正确存储在从 android 到 php 的数据库中

Question

你知道为什么当我将它存储到我的数据库时我的坐标不断更改为 xxx.000000 吗？之前，它工作正常，但是当我继续测试它时，它没有正确保存我的坐标。

例如，我想存储 120.993235 和 14.612364，然后当它在数据库中时转换为 120.000000 和 14.000000。你们能帮帮我吗？这些是我的代码。

Answer 1

在这里您可以设置 后的所有值。归零。

    int latitude = (int) (location.getLatitude());
    int longitude = (int) (location.getLongitude());

还有这个:

    ILatitude = (double)latitude;
    ILongitude = (double)longitude;

不会返回归零值。 您可以尝试一下:

    ILatitude = location.getLatitude();
    ILongitude = location.getLongitude();
