让我们写下您的姓名和gpa,如果您的GPA是3或以上,则应该说它会接受您的工作,如果不是,那么它就不会。所以这一切似乎都在起作用,但它没有注册数字?不管我说的是什么号码都表示你不接受这份工作。我不清楚我必须放置什么代码以确保它知道输入是一个数字/它知道数字是否大于3.这是我的代码。

/^(?=.*\d)(?=.*[~!@#$%^&*)(_+:[}="`-])(?=.*[a-z])(?=.*[A-Z])[~!@#$%^&*)(+:[}="`\w-]{8,}$/

你的问题是你没有比较输入而是你的常数,试试这个:

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //references to two objects: EditText and Button
        final EditText inputName = (EditText) findViewById(R.id.nameET);
        Button clickB = (Button) findViewById(R.id.showBTN);
        final EditText inputGpa = (EditText) findViewById(gpaET);
        final TextView outputa = (TextView) findViewById(messageTV);


        //setting up a listener to the clickB
        clickB.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                //reading the user name input
                String userName = inputName.getText().toString();

                //This is where you get the numeric input
                double n1 = Double.valueOf(inputGpa.getText().toString());



                if(n1 >= 3) {
                    outputa.setText("Hello, " + userName + "With your current gpa, you will be considered for the job.");
                }

                else {
                    outputa.setText("Hello, " + userName + "With your current gpa, you will not be considered for the job, sorry.");
                }


            }

        });
    }
}
