从edittext获取int的值
我试图从edittext中获取一个值，然后将其强制转换为int，以便我可以为减法/additon/等等处理该值.这是我使用的代码，但是使用此代码会导致崩溃.
I am trying to get a value from the edittext then cast it to int so that I can process the value for a substraction/additon/and so on. Here is the code I use, but I keep getting crash using this code.
number = (EditText) findViewById(R.id.editText);
angka = Integer.parseInt(number.getText().toString());
//my alternative code is like this : angka = Integer.parseInt(String.Valueof(number));
请帮助我，非常感谢
我认为，当您运行程序时，编辑文本没有值，这意味着它将返回NULL，并且NULL不能为Integer值，因此您必须检查条件类似
I think when you run your program then edit text have no value that means it will return NULL and NULL can't be a Integer value so you must have to check Condition Like
String editTextValue = number.getText().toString();
if(!TextUtils.isEmpty(editTextValue)){
angka = Integer.parseInt(editTextValue);
}
String editTextValue = number.getText().toString();
if(!TextUtils.isEmpty(editTextValue)){
angka = Integer.parseInt(editTextValue);
}
希望它对您有用.
