Question

我试图从Parse获取值，但即使在成功PUT（ting）之后，我似乎无法获得GET。该课程的数据是＆＃39;而价值是“学校开放”。（布尔类型）。我究竟做错了什么？我想要做的是获取schoolOpen的布尔值（来自Parse）并将其传递给schoolOpenStatus。

public class HomeScreen extends AppCompatActivity {

    public static boolean schoolOpenStatus = false;

    ParseObject data = new ParseObject("data");


    @Override

        setContentView(R.layout.activity_homescreen);

        TextView parseTestText = (TextView) findViewById(R.id.parseTest);

        if (schoolOpenStatus == true){
            parseTestText.setText("IT'S OPEN");
        } else {
            parseTestText.setText("SNOW DAY WOOT");
        }

        System.out.print(schoolOpenStatus);
    }

    private void setActionBarText(String actionBarText){
        TextView actionBar = (TextView) findViewById(R.id.toolbar_title);
        actionBar.setText(actionBarText);

        startActivity(intentAccount);
    }
}

此外，日志不断吐出：

(HTTPLog)-Static: isSBSettingEnabled false

Answer 1

您从错误的schoolOpen

获取ParseObject

 schoolOpenStatus = data.getBoolean("schoolOpen");

而不是使用done回复ParseObject object

 schoolOpenStatus = object.getBoolean("schoolOpen");

从Parse对象GET失败
