Question

我正在尝试使用edittext1减去edittext2将文本设置为edittext字段。

edittext3 = edittext1 - edittext2

然而，当我从edittext2中删除一个整数时，它会崩溃。

EG。通过删除＆＃34; 0＆＃34;来自＆＃34; 80＆＃34;应用程序崩溃即使是＆＃34; 8＆＃34;留在编辑文本上。

任何帮助或建议？

eactualQuantity.addTextChangedListener(new TextWatcher(){

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            //ebalance.setText((Integer.valueOf(emaximumQuantity.getText().toString())-Integer.valueOf(eactualQuantity.getText().toString())));
            if(s.toString().trim().length()>0){
                String a = emaximumQuantity.getText().toString();
                int aint = Integer.parseInt(a);
                String b = eactualQuantity.getText().toString();
                int bint = Integer.parseInt(b);


                int c = (aint - bint);

                ebalance.setText(c);
            }


        }
    });

Answer 1

您无法将int设置为textview。它必须是这样的字符串

ebalance.setText(Integer.toString(c));

当编辑文本中的文字发生变化时，应用会崩溃
