Question

我不知道这是怎么回事。我曾尝试上网。当我运行它时，我的应用程序崩溃了。实施点击列表器时问题仍然存在。我需要一些专家的帮助...我可以使用任何建议吗？

public class Update extends AppCompatActivity {

    String tempobj;
    EditText name;
    Button s;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_update);

        name = (EditText) findViewById(R.id.rightupname);

        RadioGroup rg = (RadioGroup) findViewById(R.id.radservgrp);
        String radiovalue = ((RadioButton) findViewById(rg.getCheckedRadioButtonId())).getText().toString();
        Toast.makeText(getApplicationContext(),
            radiovalue, Toast.LENGTH_LONG).show();


        ParseQuery<ParseObject> query = ParseQuery.getQuery("serviceop");
        query.whereEqualTo("no", "6382551203");
        query.findInBackground(new FindCallback<ParseObject>() {

            public void done(List<ParseObject> objects, ParseException e) {

                if (e == null) {

                    if (objects.size() > 0) {

                        for (ParseObject object : objects) {

                            String one = object.getString("name");
                            name.setText(one);
                        }

                    } else {

                        Log.d("no data", "left or right");
                    }
                } else {
                    Log.d("awserror", "left or right");
                }
            }
        });
    }


    public void onSave(View view) {

        ParseQuery<ParseObject> query = ParseQuery.getQuery("serviceop");
        query.getInBackground(makeobj("6382551203"), new GetCallback<ParseObject>() {
            public void done(ParseObject Grillen, ParseException eg) {
                if (eg == null) {

                    Grillen.put("name", name.getText().toString());
                    Grillen.saveInBackground(new SaveCallback() {
                        public void done(ParseException e) {
                            if (e == null) {

                                Log.d("MyApp", "Successfully saved!");
                            } else {

                                e.printStackTrace();

                }
            }
        });

        Log.d("sdas","sda");
    }


    public String makeobj(String nos) {

        ParseQuery<ParseObject> query = ParseQuery.getQuery("serviceop");
        query.whereEqualTo("no",nos);

我认为您的Activity需要使用onClick()方法。尝试添加此内容：

public void onSave(View view) {
    //your code goes here
}

在父类上找不到方法
