方法roundTwoDecimal返回null，您在toString变量null上运行weight_kg
labelWEIGHT.setText(weight_kg.toString());
答案 1 :(得分：0)
你写下面的代码我觉得这完全错了，也许你忘了写一些代码：
Cursor cursor = null;
Integer count=0;
while (cursor.moveToNext())
你将光标设置为null，然后你试图获得值格式，我认为这会返回NPE，
如果这没有帮助你指出第65行
//更新
您无法将列创建为名称Fitment Location，您无法在列名中使用空格。您收到此错误，因为您的表未正确创建
