那么，我的答案是否解决了您的问题？ – Shrikant

是的，但..现在米正面临新的问题，因为我张贴 –

回答

应该date.getText().toString()，而不是date.toString();

通过做money.toString()您试图将money对象转换为字符串，然后再转换为Float。对每个editText对象使用getText()方法。它应该解决你的问题。

这个错误似乎是由Float.parseFloat(money.toString())造成的，你EditText不应该包含任何字符串，只有数字，请尝试使用Float.parseFloat(money.getText().toString())

EditText没有覆盖toString()默认Object.toString()返回你包含的Editable文字，所以叫做。使用getText().toString()从EditText获得文本

使用此代码而不是您的。

对于您的信息，您必须在EditText中获得输入值意味着您必须使用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;
