答案 0 :(得分：0)
它是因为它是AppCompatActivity的覆盖方法，它是片段的覆盖方法。
更改此方法
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
}
要
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context =this;
Button SubmitButton = (Button) findViewById(R.id.button_register);
editName = (EditText)findViewById(R.id.editText_register_name);
editEmail = (EditText) findViewById(R.id.editText_register_email);
editContactNumber = (EditText) findViewById(R.id.editText_register_phone);
editFather = (EditText) findViewById(R.id.editText_register_college);
whatsappno=(EditText)findViewById(R.id.editText_register_college);
}
