Question

我正在使用AwesomeValidation库进行验证，应用程序崩溃并且给出一个空对象引用错误，我无法找到什么是null帮助。

这是活动代码：

公共类SignupActivity扩展了AppCompatActivity {

TextInputEditText email,pass1,pass2;
FirebaseAuth mAuth;
AwesomeValidation mAwesomeValidation;
ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signup);

    progressDialog = new ProgressDialog(this);
    progressDialog.setMessage("Registering user");
    email = (TextInputEditText) findViewById(R.id.s_email);
    pass1 = (TextInputEditText) findViewById(R.id.s_pass1);
    pass2 = (TextInputEditText) findViewById(R.id.s_pass2);

    mAuth = FirebaseAuth.getInstance();

    mAwesomeValidation = new AwesomeValidation(TEXT_INPUT_LAYOUT);
    mAwesomeValidation.addValidation(this,R.id.s_email, Patterns.EMAIL_ADDRESS, R.string.emailerr);
    String regexPassword = "(?=.*[a-z])(?=.*[A-Z])(?=.*[\\d])(?=.*[~`!@#\\$%\\^&\\*\\(\\)\\-_\\+=\\{\\}\\[\\]\\|\\;:\"<>,./\\?]).{8,}";
    mAwesomeValidation.addValidation(this, R.id.s_pass1, regexPassword, R.string.passerr);
    mAwesomeValidation.addValidation(this, R.id.s_pass2, R.id.s_pass1, R.string.passerr);


}

public void signup(View view){
    email.setError("Enter valid email");
    if (mAwesomeValidation.validate()){
        String mail = email.getText().toString().trim();
        String pass = pass1.getText().toString().trim();
        progressDialog.show();

        mAuth.createUserWithEmailAndPassword(mail,pass).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()){
                    Toast.makeText(getApplicationContext(),"Registered successfully",Toast.LENGTH_SHORT).show();
                    startActivity(new Intent(getApplicationContext(),LoginActivity.class));
                }
                else {

                    Toast.makeText(getApplicationContext(),"Registration Error",Toast.LENGTH_SHORT).show();
                }
            }
        });

        progressDialog.dismiss();

    }
}

我收到此错误

我也尝试过放入OnStart（）方法 得到同样的错误？
