我正在尝试从用户那里获取输入，然后将其存储在我的数据库中，但每次我按下保存..我得到运行时错误我正在复制我的catlog下面。我经常检查我的代码很多次但没有弄清楚它出错的地方。请帮我。 Thanx提前
这就是我的catlog所说的

答案 0 :(得分：1)
应该是date.getText().toString()而不是date.toString();
通过执行money.toString()，您尝试将money对象转换为String，然后转换为Float。对每个getText()对象使用editText方法。它应该解决你的问题。
答案 1 :(得分：0)
此错误似乎是由Float.parseFloat(money.toString())造成的，您的EditText不应包含任何字符串，仅包含数字，请尝试使用Float.parseFloat(money.getText().toString())
EditText不会覆盖toString()以返回其中包含的Editable文本，因此默认调用Object.toString()。使用getText().toString()获取EditText
答案 2 :(得分：0)
使用此代码代替您的代码。
为了您的信息，您必须在EditText中获取输入的值，这意味着您必须使用getText()。
switch (view.getId()) {
case R.id.addnote_save:
note = datasource.createNote(date.getText().toString(),Float.parseFloat(money.toString()),category.toString(),description.getText().toString());
break;
