Question

基本上，我有一个edittext框，通过xml限制为10个数字。当我输入少于7的东西时，它会显示一个祝酒词。 7个整数保存字符串。 8或9个整数显示其适当的吐司。但是，当我输入完整的10位数字时，我收到此错误...

和方法......

 public void onOk(View src) {
        Product p = new Product();
        p.name = _name.getText().toString();
        p.number = Integer.parseInt(number.getText().toString());

        if ((number.getText().toString().trim().length() == 7)) {
            Toast.makeText(getApplicationContext(), "Please enter the full 10 digit phone number for best results",   Toast.LENGTH_LONG).show();
        Intent result = new Intent();
        result.putExtra("product", p);
        setResult(RESULT_OK, result);
        finish();
        } 
        else if (number.getText().toString().trim().length() < 7) {
            Toast.makeText(getApplicationContext(), "Please enter at least 7 digits",   Toast.LENGTH_LONG).show();
        }
        else if ((number.getText().toString().trim().length() == 8) || number.getText().toString().trim().length() == 9)) {
            Toast.makeText(getApplicationContext(), "You entered " + _price.getText().toString().trim().length() + ". Please enter a 10 digit phone number.",   Toast.LENGTH_LONG).show();
        } else {
            Intent result = new Intent();
            result.putExtra("product", p);
            setResult(RESULT_OK, result);
            finish();
        }
        }

我已经尝试了所有我能想到的东西而没有解决它。我确定这只是我忽略的事情。

Answer 1

当您输入应用程序崩溃的任何内容时，java中int的最大值为2,147,483,647。尝试使用最大值为9,223,372,036,854,775,807的long。

此外，如果您要保存电话号码，我建议您使用字符串，除非您需要对电话号码进行数学计算（不太可能）。某些电话号码包含＆＃39; +＆＃39;，＆＃39; *＆＃39;，＆＃39;＃＆＃39;等字符。

Answer 2

使用double而不是int值

试图保存10位数的电话号码，但它会引发无效的int错误
