android Parse.com获取具体数据

Question

这是我的截图

在我的activity.java

中

    btnSearchemail = (Button) findViewById(R.id.btnSearchemail);
    txtSearchemail = (EditText) findViewById(R.id.txtSearchemail);

    Searchemail = txtSearchemail.getText().toString();

    txtFname = (TextView) findViewById(R.id.txtFname);
    txtLname = (TextView) findViewById(R.id.txtLname);



    btnSearchemail.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            final ParseQuery<ParseObject> query = ParseQuery
                    .getQuery("account");
            query.whereEqualTo("email", Searchemail);
            query.findInBackground(new FindCallback<ParseObject>() {
                public void done(List<ParseObject> results, ParseException e) {
                    if (e == null) {
                        // results contains a list of all the emails found

                        for (ParseObject x : results) {
                            String fname = x.getString("firstName");
                            String lname = x.getString("lastName");


                        }
                        // i replace it here this is edited/updated
                        txtFname.setText(fname);
                        txtLname.setText(lname);

                    } else {
                        // error
                        Toast.makeText(Sample.this.getApplicationContext(),
                                "error", Toast.LENGTH_LONG).show();
                    }
                }
            });

        }
    });

我想根据我在编辑文本中添加的电子邮件检索特定数据。单击按钮时没有任何反复发生。

您需要调用查询。注意这个函数是异步的。可以找到文档here。

ParseQuery<ParseObject> query = ParseQuery.getQuery("account");
query.whereEqualTo("email", emailsave);
query.findInBackground(new FindCallback<ParseObject>() {
    public void done(List<ParseObject> results, ParseException e) {
        if (e == null) {
            // results contains a list of all the emails found
            for (ParseObject x : results) {                     
                 String fname = x.getString("firstName");
                 String lname = x.getString("lastName");
                 // Put breakpoint here and see what the variables contain
                 txtFname.setText(fname);
                 txtLname.setText(lanme)
            }
        } else {
            // error
        }
    }
});
