Question

我正在尝试检查文本框中的值是否在4到80之间，但是不能我能做到这一点，但它不是我需要的

 final String checkage = age.getText().toString();
    if(checkage.equals(4)   || checkage.equals(80) ) {
        Toast.makeText(this, "You must be older than 4 and younger than 80", Toast.LENGTH_SHORT).show();
        return;
}

Answer 1

使用此：

final String checkage = age.getText().toString();
int value = Integer.parseInt(checkage);

if(value >= 4 && value <= 80) {
      Toast.makeText(this, "You must be older than 4 and younger than 80", Toast.LENGTH_SHORT).show();
      return;
}

在这种情况下，

' || '对您没用。

你的逻辑错了。你需要做这样的事情。

检查值是否在一系列数字之间
